Use these selected concepts to connect assessment findings with defensible clinical decisions and clear explanations to patients. They cover clinical care, communication, professionalism, and management responsibilities relevant to the Overseas Registration Exam Part 2 (ORE Part 2). Read them alongside the official dentist outcomes in Preparing for Practice and apply them during supervised practical and communication rehearsal.
Evidence and assessment foundations
1. Integrating evidence with the patient's circumstances
Standard 7.1 requires good quality care based on current evidence and authoritative guidance, delivered with a holistic and preventative approach appropriate to the individual patient. Evidence informs which options are suitable, but the patient must be listened to, with preferences and concerns taken into account. This principle guides decision-making; it does not by itself establish the suitability of any particular procedure.
Worked example: During assessment of a toothache patient, two restorative options both meet current guidance. The dentist explains the benefits, limitations and costs of each, asks about the patient's work commitments and anxiety, and agrees a plan reflecting those concerns.
Mistake to avoid: Following a guideline recommendation automatically for every patient without checking whether the care is appropriate to that individual's circumstances and preferences.
Supporting reference: [3]
2. Evidence certainty and recommendation strength
The ADA chairside guide separates GRADE certainty of evidence from strength of recommendations. Very low certainty means very little confidence in the effect estimate, so findings remain possible rather than proven. A conditional recommendation means different choices will be appropriate for individual patients, and the clinician must help each patient decide according to their own values and preferences rather than treating the suggestion as compulsory.
Worked example: For a vital posterior tooth with a moderate caries lesion, the guideline panel conditionally suggests prioritising several restorative materials, with very low certainty. The dentist therefore presents the suitable material options and supports the patient in choosing, without claiming any single material is certainly best.
Mistake to avoid: Describing a conditional recommendation backed by very low certainty evidence as a proven, compulsory intervention that every patient must receive.

3. Medication history before assessing bleeding risk
When taking or confirming a medical history before treatment likely to cause bleeding, ask about current or planned use of anticoagulants and antiplatelet drugs and also other prescribed and non-prescribed medications, because these affect bleeding risk and potential drug interactions. Recording this history informs the bleeding-risk assessment; it does not itself authorise the dentist to stop or change any patient's existing treatment.
Worked example: Before planning an extraction, a patient discloses a direct oral anticoagulant plus an over-the-counter painkiller bought independently. The dentist documents both medicines, considers their combined relevance to peri-operative bleeding, and arranges appropriate assessment rather than advising the patient to alter any medication.
Mistake to avoid: Recording only prescribed medicines, or trusting an outdated medication list, so over-the-counter products affecting bleeding risk are missed.
Supporting reference: [12]
4. Endodontic difficulty and the treatment pathway
Case difficulty assessment tools may assist in determining treatment complexity and suggesting appropriate treatment delivery pathways, which is particularly relevant for operators with limited endodontic experience. However, treatment should only be undertaken when its technical demands and required knowledge fall within the competencies and abilities of the operator. Completing a difficulty form supports clinical judgement; it does not certify competence to attempt a complex case.
Worked example: A molar needing root canal treatment presents with calcified canals and severe curvature. Difficulty assessment places the case beyond the dentist's current abilities, so the dentist explains the findings to the patient and refers to a colleague with suitable specialist skills rather than attempting treatment.
Mistake to avoid: Treating a completed difficulty assessment form as permission to undertake an unfamiliar complex case beyond current competence.

Communication, consent and clinical records
5. Including the child in the conversation
During paediatric consultations, direct the conversation so the child remains an active participant rather than a passive subject. Build rapport with the accompanying adult and agree how that adult will support and encourage the child in the surgery, while also speaking directly with the child. This applies to children and young people up to 18 years within the SDCEP guidance population.
Worked example: In an OSCE station, the candidate asks an eight year old what worries her about having a filling, then asks her mother how she plans to help during the visit, and the station concludes with both feeling heard and the child agreeing to proceed.
Mistake to avoid: Directing every question to the accompanying adult while the child sits silently throughout the whole consultation.
Supporting reference: [5]
6. Shared decisions and valid consent for child care
Children and their parents or carers should both take part in decisions about oral health care, and valid consent for planned treatment must be established from the child and/or the parent or carer as appropriate. Taking part in discussion differs from holding authority to consent, and the passages do not set out age, capacity or parental responsibility rules.
Worked example: A carer wants a primary molar extracted, but the child says the tooth feels fine. The clinician explores the concern with both, explains the options, agrees a plan everyone accepts, and confirms valid consent from the appropriate person before any treatment starts.
Mistake to avoid: Treating the preference of the carer as automatically settling consent for a planned procedure in every case.
Supporting reference: [5]
7. Recording care when it occurs
Records, including the medical history, should be made and kept accurate and complete at the time care is provided, and written so another member of the dental team can understand them. The BES passage frames this as a general professional duty that applies well beyond endodontic treatment.
Worked example: During a restorative appointment the clinician records the updated medical history, the presenting complaint, the findings, the agreed plan and the care given before the patient leaves, so the colleague covering the next visit can follow the account without needing clarification.
Mistake to avoid: Reconstructing important clinical details hours later from memory instead of writing them at the time of care.
Supporting reference: [7]
8. Identifiable entries and transparent amendments
Whether records are handwritten or digital, entries should be dated, timed and signed by an easily identifiable author. Any amendment should remain clear, carry its own date and be signed by the person who made it, so the record shows what changed and who changed it. No particular software workflow is specified.
Worked example: A clinician notices an incorrect tooth number in the paper notes. She strikes it through with a single line so it stays legible, writes the correction beside it, and adds her signature and the date, leaving the original entry visible and the amendment attributable.
Mistake to avoid: Deleting or overwriting an entry so the amendment itself and the identity of its editor become untraceable.
Supporting reference: [7]
9. Protecting digital records and transfers
Digital clinical and dental records should be backed up regularly and have access restricted to appropriate members of practice staff. When records are transferred electronically, the provider must ensure, as far as practically possible, that only the recipient can access the data, which should be password-protected with the recipient advised of this, and the transfer should use end-to-end encryption.
Worked example: A practice transfers a patient's referral records to the intended specialist using end-to-end encryption and password protection, advises the specialist that the files are password-protected, and maintains regular backups with access restricted to appropriate practice staff.
Mistake to avoid: Assuming that a portal described only as encrypted and password-protected necessarily provides the end-to-end encryption required for transfers.
Supporting reference: [7]
10. Documenting decisions made with colleagues
When colleagues are consulted about a patient's treatment, the discussion and any decisions reached or changed should be documented in that patient's clinical notes. Recording the exchange keeps the reasoning behind the plan visible to the dental team and supports continuity if another colleague later reviews or continues the patient's care.
Worked example: After a periodontist suggests a modified sequencing of care, the treating dentist writes in the notes what was discussed, who advised it, and the revised plan adopted for the patient.
Mistake to avoid: Discussing a changed treatment plan by phone and recording nothing, leaving the record showing only the original, superseded decision.
Supporting reference: [3]
Professional responsibilities and boundaries
11. Dignity and individual treatment
Every patient should be treated with dignity and respect at all times, and fairly, as an individual, without discrimination. This spans the whole care pathway rather than only treatment selection, and includes respecting patients' cultures and values and making reasonable adjustments so that care is appropriate for each individual person.
Worked example: Before planning care for a patient whose observances affect appointment timing, the team asks about preferences directly, adjusts scheduling where practicable, and records the agreed arrangements in the notes.
Mistake to avoid: Assuming a patient will decline certain options because of their background instead of asking about their individual preferences.
Supporting reference: [3]
12. Honesty across professional activities
Registrants must justify the trust placed in them by acting honestly and fairly with patients, colleagues and the public. This duty covers business and education activities as well as clinical dealings, so advertising, promotional material and course or service descriptions must be accurate and not misleading, in line with ethical advertising guidance.
Worked example: When promoting a hands-on course, a dentist states clearly which parts are lecture-based and which techniques attendees will not practise, so colleagues can judge accurately whether the training suits their needs.
Mistake to avoid: Overstating experience in a course advertisement, treating promotional material as outside the honesty standards that govern clinical dealings.
Supporting reference: [3]
13. Prerequisites for undertaking treatment
Before carrying out any task or treatment, all four prerequisites must be satisfied: appropriate training, competence, confidence and indemnity. Attending a course does not by itself demonstrate competence or confidence for every case. When confidence to provide a particular treatment is lacking, the clinician must refer the patient to an appropriately trained colleague rather than proceed.
Worked example: A dentist who has recently completed an implant course is asked to place an implant but feels unsure about managing the anatomy. Having trained but not yet feeling confident or fully competent, they refer the patient to an experienced implant colleague.
Mistake to avoid: Assuming a course certificate automatically proves competence and confidence for every case the clinician might subsequently encounter in practice.
Supporting reference: [3]
14. Seeking independent advice about personal impairment
When a clinician knows or suspects that their health, behaviour or professional performance may put patients at risk, they must consult a suitably qualified colleague immediately and follow the advice given. Suspected risk is enough to trigger this duty, and self-assessment of the risk posed to patients is never an acceptable substitute for independent opinion.
Worked example: A dentist notices that a worsening tremor seems to be affecting the precision of handpiece control. Suspecting patients may be at risk, they consult an occupational health physician the same day and follow the resulting advice to pause certain treatments pending assessment.
Mistake to avoid: Continuing to treat solely because personal judgment suggests the risk to patients remains manageable without independent input.
Supporting reference: [3]
15. Maintaining appropriate patient boundaries
Clinicians must maintain appropriate boundaries in their relationships with patients and must not take advantage of their position as dental professionals. The guidance sets out the boundary principle without defining every possible relationship scenario, so clinicians should judge whether professional trust is being used to pursue any personal benefit.
Worked example: A patient being treated for dental phobia expresses great gratitude and offers the dentist a paid business partnership. Recognising that accepting could exploit the trust created by the professional relationship, the dentist politely declines and records the discussion in the notes.
Mistake to avoid: Treating a patient's trust and gratitude as permission to blur professional and personal interests for private gain.
Supporting reference: [3]
Dental imaging principles
16. Balancing diagnostic benefit and radiation risk
Dental X-ray imaging is indispensable for efficient diagnosis and effective treatment planning, but its benefits must be balanced against ionising radiation risks to the patient, dental team members and other persons. This clinical benefit-risk principle from the 2020 guidance is not a statement of current statutory roles, and digital imaging may offer greater diagnostic yield at potentially lower exposure than film.
Worked example: Before repeating a radiograph, a dentist confirms that new clinical findings justify additional imaging rather than re-exposing the patient unnecessarily, then weighs the expected diagnostic benefit against exposure risks to the patient, dental team and others before proceeding.
Mistake to avoid: Treating a potentially useful radiograph as having no exposure-related risk to patients, staff or other persons.
Supporting reference: [11]
17. Digital imaging offers potential dose reduction
Digital technology can improve diagnostic yield and may potentially lower radiation exposure, but the source describes this as a potential benefit rather than an automatic guarantee. No universal digital-versus-film dose ratio is established here, so practices should still review appropriate equipment use and image quality rather than assuming every exposure is automatically lower.
Worked example: A practice newly using digital sensors continues to audit image acceptability and justify each exposure against selection criteria, treating any dose benefit as potential and dependent on appropriate use rather than automatic for every image.
Mistake to avoid: Telling a patient that switching to digital sensors guarantees a fixed percentage dose reduction on every radiograph taken.
Supporting reference: [11]
18. Image quality depends on equipment and its use
Although image quality has improved dramatically over the years, it remains highly dependent on the correct selection, use and maintenance of X-ray equipment. This passage establishes no exposure settings, fault-specific diagnoses or device-specific operating instructions, so when quality deteriorates the practice should review equipment suitability, use and maintenance rather than attributing the problem solely to the patient.
Worked example: After several underexposed periapical images, the dental team reviews equipment suitability, maintenance arrangements and how operators are using the equipment, instead of concluding that individual patients were solely responsible for the deterioration in quality.
Mistake to avoid: Blaming repeated poor images on patient movement without first reviewing equipment maintenance records and operator technique.
Supporting reference: [11]
Assessment and prevention in children
19. Examining clean, dry teeth systematically
Caries assessment in children includes visual examination of both primary and permanent dentitions on clean, dry teeth, using a tooth-by-tooth approach. This examination sits within the wider child assessment and does not replace other indicated investigations, so the presenting complaint should not narrow the scope of the caries examination performed.
Worked example: A child attends reporting pain in one lower molar; the clinician still cleans, dries and visually examines each primary and permanent tooth systematically across the whole mouth, rather than inspecting only the symptomatic quadrant.
Mistake to avoid: Examining only the tooth linked to the presenting complaint and skipping the rest of the dentition entirely.
Supporting reference: [5]
20. Bitewings and the extent of childhood caries
When assessing caries in children, bitewing radiographs may be considered to diagnose the extent of any lesion accurately, including its proximity to the pulp. Consideration is not a blanket instruction to expose every child, so an appropriate imaging assessment remains necessary, and visible surface appearance alone cannot establish a lesion's full extent.
Worked example: A clinician is uncertain whether a lesion on a primary molar approaches the pulp, so bitewings are considered as part of an appropriate imaging assessment to inform pulpal proximity, rather than radiographs being taken routinely for all children.
Mistake to avoid: Exposing bitewings for every child at every visit regardless of clinical findings because guidance mentions them.
Supporting reference: [5]
21. Lesion activity and progression are separate assessments
SDCEP advises clinicians to assess the activity of each carious lesion clinically and to use radiographs to judge progression over time. These are two distinct judgements: clinical activity status and radiographic change between visits. Unless there is evidence that a lesion is arrested, it should be assumed active.
Worked example: A child has a shallow fissure lesion with no documented evidence of arrest, so it is recorded as active for planning purposes. Bitewing radiographs taken at intervals are then considered separately to judge whether the lesion has progressed over time.
Mistake to avoid: Recording a lesion as arrested simply because the child reports no symptoms, without clinical or radiographic evidence supporting arrest.
Supporting reference: [5]
22. Primary-tooth risk before exfoliation
For primary teeth, SDCEP directs clinicians to assess the risk of carious lesions causing pain or infection before exfoliation, and to use that assessment to inform a suitable management strategy. Expected shedding does not remove the need to evaluate the tooth's likely course while it remains in the mouth.
Worked example: A carious primary molar is expected to shed within a year, but the clinician still assesses its likely course before exfoliation. Because intervening pain or infection remains possible, the management strategy chosen addresses that risk rather than relying on shedding alone.
Mistake to avoid: Dismissing disease in a primary tooth on the grounds that the tooth will eventually exfoliate, without assessing pain or infection risk.
Supporting reference: [5]
23. Assessing hypomineralised molars individually
SDCEP recommends assessing any hypomineralised molars independently to determine the extent of disease and likely prognoses. Affected molars can differ considerably in presentation, so each tooth requires its own evaluation. This supports individual assessment; it does not itself dictate any particular extraction or restorative protocol for these teeth.
Worked example: Two hypomineralised first permanent molars show different lesion extents and sensitivities. The clinician assesses each tooth on its own merits, recording separate disease extent and likely prognoses, rather than assuming both teeth share the same outlook or require identical management.
Mistake to avoid: Assigning the same prognosis to every hypomineralised molar in a child's mouth instead of assessing each affected tooth independently.
Supporting reference: [5]
24. Protecting permanent teeth within the child's plan
Within child care planning, SDCEP sets priorities that include relieving pain or infection if present, applying prevention informed by caries risk assessment, and focusing on prevention of caries in the permanent dentition before managing caries in the primary dentition. Preventive priority does not justify delaying relief of existing pain or infection.
Worked example: A child presents with primary-tooth caries and newly erupted permanent molars. The plan relieves existing symptoms where present, prioritises preventive care for the permanent teeth, and manages the primary-tooth lesions appropriately, rather than postponing prevention until restorative treatment is complete.
Mistake to avoid: Treating prevention of permanent-tooth caries as something to add only after all restorative work has been finished.
Supporting reference: [5]
Periodontal treatment decisions
25. Periodontal control is a continuing partnership
Managing periodontitis depends on effective daily self-care by the patient combined with professional treatment in the dental practice, and it also involves addressing modifiable risk factors such as smoking and diabetes control. The guidance presents this as a lifelong partnership between patient and clinician; it does not extend to managing the patient's diabetes medication, which remains a medical matter.
Worked example: A patient with periodontitis believes six-monthly professional cleaning alone will control the disease. The clinician explains that daily interdental cleaning, toothbrushing, smoking cessation support and coordinated diabetes care all contribute alongside in-surgery treatment.
Mistake to avoid: Describing periodontal treatment as a single completed procedure and failing to secure the patient's continuing self-care role.
Supporting reference: [6]
26. Correcting local plaque-retentive factors
Step 1 of therapy for diagnosed periodontitis includes removing supragingival plaque and calculus using an appropriate method, together with correcting local factors that retain plaque, such as overhanging restorations or denture design features that hinder cleaning. Addressing these retentive factors supports the patient's plaque control rather than replacing it.
Worked example: During periodontal planning a radiograph and probing reveal an overhanging restoration on a molar. Correction of this overhang is planned as part of Step 1, alongside supragingival deposit removal and oral hygiene instruction.
Mistake to avoid: Scaling away visible deposits while leaving an identified overhanging restoration or poorly designed denture uncorrected in the mouth.
Supporting reference: [6]
27. Selecting sites for subgingival plaque removal
For patients with diagnosed periodontitis, Step 2 involves subgingival professional mechanical plaque removal at sites with probing depth of at least 4 mm where subgingival deposits are present or which bleed on probing. The response to Step 1 should be assessed first, and local anaesthesia or site-specific instruments may be needed.
Worked example: A patient proceeding to Step 2 has a 5 mm pocket that bleeds on probing after Step 1 review. This site meets the stated criteria for subgingival instrumentation, and local anaesthesia may be offered for comfort.
Mistake to avoid: Instrumenting every site over 4 mm regardless of deposits or bleeding, and skipping the Step 1 response assessment.
Supporting reference: [6]
28. Explaining changes after periodontal treatment
Patients should be advised that some discomfort and sensitivity can occur immediately after periodontal treatment. As pocketing and gingival swelling reduce during stabilisation, interdental black triangles or smooth surface recession may become more noticeable. These are possible changes to explain in advance, not a substitute for ongoing assessment of postoperative findings.
Worked example: After Step 2 a patient notices new interdental spaces as swelling settles. The clinician explains that reduced gingival swelling can reveal such spaces, while examining the tissues to confirm the findings at review.
Mistake to avoid: Promising the patient that successful periodontal therapy will leave the gingival contours and appearance completely unchanged.
Supporting reference: [6]
29. Residual periodontal disease requires reassessment
After completing Step 2 of therapy, the SDCEP guidance directs clinicians to assess the response before deciding whether further periodontal treatment is indicated. Where residual disease persists after Steps 1 and 2, the patient should be involved in a discussion of Step 3 options, which may include further non-surgical care, surgical treatment, or onward referral for specialist periodontal care.
Worked example: A patient completes subgingival PMPR, and reassessment at a review visit still shows pocketing with bleeding at several sites. The clinician records the residual disease, discusses Step 3 possibilities with the patient, including referral, and agrees a plan rather than discharging to maintenance.
Mistake to avoid: Declaring active treatment finished and moving the patient into routine maintenance while residual pockets with bleeding remain unaddressed and undiscussed.
Supporting reference: [6]
30. Maintenance after active periodontal treatment
Once the active phase of periodontal treatment is complete, the SDCEP guidance advises arranging and encouraging regular maintenance care as Step 4 of therapy. The stated purpose is to prevent recurrent disease where possible, detect any areas that do recur, and maintain the stability achieved through earlier treatment steps.
Worked example: Following completion of active therapy, a patient is placed on a review schedule with periodic probing and oral hygiene reinforcement. At one visit, an isolated site shows new bleeding on probing, so the recurrence is identified early through maintenance monitoring and discussed with the patient.
Mistake to avoid: Treating the end of the active phase as permanent discharge, so no monitoring exists to detect recurrent periodontal disease.
Supporting reference: [6]
Caries restoration and pulp therapy
31. Selective and non-selective removal endpoints
The ADA chairside guide defines selective carious tissue removal as excavation stopping at soft or firm dentine, and non-selective removal as excavation continuing until hard dentine is reached. These definitions apply to vital, non-endodontically treated permanent teeth in the guidance, and the endpoint reached determines which label describes the approach.
Worked example: A deep lesion in a vital permanent molar is excavated until the dentine feels firm, leaving no further removal planned. Under the ADA definitions this is selective removal to firm dentine, not non-selective removal, because hard dentine was not reached.
Mistake to avoid: Labelling any caries excavation as complete removal without checking whether the endpoint was soft, firm or hard dentine.
Supporting reference: [16]
32. Stepwise removal has a planned second stage
The ADA guide describes stepwise carious tissue removal, also called two-step removal, as excavation first to soft dentine with placement of a temporary restoration. Months later, the restoration and remaining carious tissue are removed to firm dentine before a permanent restoration is placed, so a planned re-entry stage distinguishes this approach.
Worked example: A deep lesion in a vital permanent tooth is excavated to soft dentine and sealed with a temporary restoration. Several months later, a planned re-entry removes the restoration and residual carious tissue to firm dentine, and a permanent restoration completes the two-step sequence.
Mistake to avoid: Calling a single-visit excavation to soft dentine stepwise removal when no second stage or re-entry visit has been planned.
Supporting reference: [16]
33. Selective removal recommendations have a defined scope
For vital, non-endodontically treated permanent teeth needing a restoration without pulp therapy, the ADA panel conditionally suggests prioritising selective carious tissue removal. Moderate lesions are ICDAS 3 to 4, compared against non-selective removal; advanced lesions are ICDAS 5 to 6, compared against stepwise and non-selective removal. Certainty is very low, and this is an ADA suggestion rather than a UK regulatory mandate.
Worked example: A 45-year-old patient has an ICDAS code 5 lesion on a vital permanent molar that requires a restoration without pulp therapy. Within this scope, selective carious tissue removal is the conditionally prioritised approach over stepwise and non-selective removal.
Mistake to avoid: Extending this recommendation to primary teeth or to teeth requiring pulp therapy goes beyond its defined population and scope.
Supporting reference: [16]
34. Isolation and curing affect material feasibility
The ADA guide attaches feasibility footnotes to particular restoration categories: conventional and resin-modified GIC may be preferable when tooth isolation cannot be achieved, and conventional GIC may be preferable when light-curing is not feasible. These are qualified preferences for the guide's vital permanent-tooth population, not universal material rankings, so clinicians check whether a material's requirements can be met before selection.
Worked example: A vital permanent posterior tooth needs a Class II restoration, but reliable isolation cannot be achieved and the curing light is unavailable. For this category, conventional GIC may be a preferable option under the guide's feasibility footnotes.
Mistake to avoid: Selecting a material without first checking whether isolation and light-curing requirements can actually be met in that clinical situation.
Supporting reference: [16]
35. Restorative options for permanent root caries
For moderate or advanced root caries lesions on vital, anterior and posterior, non-endodontically treated permanent teeth requiring a restoration without pulp therapy, the ADA suggests conventional GIC or resin-modified GIC. This conditional recommendation carries low certainty, and the panel assigned no prioritization between the two materials, so individual suitability and feasibility still guide the final choice.
Worked example: An older adult has a moderate root caries lesion on a vital permanent premolar requiring restoration without pulp therapy. Both GIC types are feasible, and because the guide ranks neither material as superior, selection depends on the individual circumstances.
Mistake to avoid: Inventing a preferred ranking between conventional and resin-modified GIC for root caries when the panel deliberately assigned no prioritization.
Supporting reference: [16]
36. Pulpotomy and pulpectomy differ anatomically
SDCEP defines pulpotomy as pulp therapy in which instrumentation is confined to the coronal pulp chamber, whereas pulpectomy extends instrumentation to include the root canal system. These anatomical definitions describe extent of instrumentation only; they do not by themselves establish treatment indications, technique, materials or prognosis for either procedure.
Worked example: A written plan for a young patient describes instrumentation extending into the root canal system before placing a permanent restoration. This describes pulpectomy rather than pulpotomy, because instrumentation passes beyond the coronal pulp chamber.
Mistake to avoid: Using pulpotomy and pulpectomy interchangeably because both involve pulp tissue, despite their clearly different anatomical extents of instrumentation.
Supporting reference: [5]
Removable prosthesis assessment
37. Support and stability describe different properties
Support concerns the foundation of teeth and soft tissue on which a removable prosthesis rests, while stability concerns its resistance to displacement under functional, horizontal and rotational stresses. For distal-extension partial dentures these are separate properties: a denture can rest on an adequate foundation yet still move during function, so foundation quality and resistance to movement need separate assessment.
Worked example: At delivery of a distal-extension partial denture, the clinician notes that the base rests on healthy ridge tissue and abutments, yet the base shifts when the patient mimics chewing; support appears adequate while stability still requires its own separate clinical testing.
Mistake to avoid: Concluding that because supporting teeth and tissues are present and healthy, the denture must also be stable during function.
Supporting reference: [10]
38. Indirect-retainer lift indicates vertical instability
In a distal-extension RPD, the article's chairside assessment applies finger pressure to the distal-most tooth on the base while watching the anterior-most indirect retainer; lifting of that retainer indicates the prosthesis is not vertically stable. This interpretation is specific to that assessment rather than a universal test, and the finding may reflect poor tissue fit, tissue compression, or both.
Worked example: A recorded delivery assessment shows the anterior indirect retainer lifting when the distal base is loaded by finger pressure; the clinician documents vertical instability as a possible sign of poor tissue fit or tissue compression, without yet choosing a reline method.
Mistake to avoid: Treating a well-seating, satisfactory-looking framework as proof that the distal extension base is vertically stable without testing.
Supporting reference: [10]
39. Interpreting a denture-base adaptation record
In the article's adaptation assessment, polyvinyl siloxane material is applied without adhesive to the tissue surface and the prosthesis is seated while the framework rests are held fully in position; thick areas indicate space between resin and tissue, while thinner areas indicate closer adaptation. This interpretation holds under those conditions and is not a numerical fit standard.
Worked example: A silicone adaptation record taken with the rests fully seated shows a thick distal region beside a thin mid-ridge region; the clinician reads the thick area as more space beneath the base, not as better adaptation.
Mistake to avoid: Reading greater impression material thickness under the base as evidence of closer fit or improved support.
Supporting reference: [10]
40. Distal loading and rotation affect tissues and abutments
Because occlusal forces establish a fulcrum at the terminal abutment, rotation of a distal-extension base concentrates the greatest pressure at the distal-most support area, and depending on framework design and clasp rigidity it can impose non-axial forces that may be detrimental to a weak terminal abutment; effects depend on design rather than being calculable certainties.
Worked example: During delivery of a distal-extension partial denture, detected base rotation raises concern about both uneven pressure on the distal ridge and possible non-axial loading of the terminal abutment, whose risk depends on framework design and clasp rigidity rather than being predictable.
Mistake to avoid: Attributing detected rotational movement solely to patient adaptation instead of evaluating tissue loading and abutment forces.
Supporting reference: [10]
Developing occlusion and orthodontic decisions
41. Orthodontic assessment extends beyond tooth alignment
Orthodontic assessment considers the developing occlusion as a whole rather than tooth alignment alone. BOS guidance directs practitioners to examine the face transversely for chin or nasal asymmetry, assess the soft tissues of the lips and tongue, and then record intraoral findings including incisor inclination, alignment, crowding and the incisor relationship such as overjet. These are selected assessment elements from BOS guidance, not a complete orthodontic examination protocol.
Worked example: During a routine examination of a teenager, a clinician notices mild upper-incisor crowding. Following BOS guidance, they also assess facial symmetry transversely, lip and tongue posture, and the incisor relationship before recording an overall developing-occlusion summary.
Mistake to avoid: Reducing orthodontic assessment to whether the front teeth look straight, ignoring facial asymmetry and soft tissues.
Supporting reference: [9]
42. Lip posture can contribute to incisor position
Soft tissues often adapt to abnormal tooth positions and may worsen a malocclusion caused primarily by the skeletal pattern. BOS guidance notes that a lower lip resting behind the upper incisors, helping to form an anterior oral seal, can procline those incisors further and contribute to any increase in overjet. This is a contributing soft-tissue relationship, not proof of the sole cause of a patient's malocclusion.
Worked example: A patient presents with an increased overjet. The clinician observes the lower lip resting behind the upper incisors and records it as a likely contributor to proclination, while also considering the underlying skeletal pattern rather than a single cause.
Mistake to avoid: Attributing the whole malocclusion to one observed soft-tissue feature rather than a contributing factor.
Supporting reference: [9]
43. Late lower-incisor crowding and third molars
Late lower-incisor crowding is so prevalent that BOS guidance describes it as possibly the norm. It attributes this crowding to late growth changes and soft-tissue maturation rather than pressure from erupting permanent third molars. This concept concerns explaining late lower-incisor crowding only, not other indications for third-molar management, so it does not by itself determine any third-molar treatment decision.
Worked example: A young adult reports new lower-incisor crowding and blames wisdom teeth pushing. The clinician explains that BOS guidance attributes such crowding to late growth changes and soft-tissue maturation, and avoids linking it directly to third-molar pressure.
Mistake to avoid: Recommending third-molar removal solely from that crowding explanation without other clinical indications.
Supporting reference: [9]
44. Treatment need includes the patient's perspective
An observed malocclusion does not alone determine whether treatment is appropriate. BOS guidance advises weighing the severity of the occlusal problem alongside the patient's attitude, motivation and oral health, and seeking specialist advice if in any doubt. Discussions should cover likely compliance, probable appliances, treatment duration and retention where appropriate. Irreversible extraction decisions require particular care, and no extraction pattern is prescribed here.
Worked example: An adult mentions mild spacing that does not concern them. The clinician discusses whether change is wanted, likely compliance, appliance options, duration and retention, and decides to seek specialist advice before proposing any definitive plan.
Mistake to avoid: Prescribing treatment solely because an occlusal variation is visible, without considering patient attitude or oral health.
Supporting reference: [9]
Bleeding risk and dental infection
45. Expected bleeding and bleeding complications
When treating patients taking anticoagulant or antiplatelet medication, distinguish procedures that are likely to cause bleeding from those that are not, then judge whether a bleeding procedure carries a low or a relatively higher risk of postoperative bleeding complications, meaning prolonged or excessive bleeding, or bleeding not controlled by initial haemostatic measures, noting that higher risk describes a relative category rather than a high-risk treatment.
Worked example: A dentist assessing a warfarin-treated patient plans root surface debridement, which is expected to cause bleeding; consulting the guidance categories, they judge it low risk of postoperative bleeding complications, while a flap-raising procedure in the same mouth would be assessed in the higher category.
Mistake to avoid: Treating the higher-risk label as meaning the procedure is universally high risk, rather than a relative category within dental treatment judged individually.
Supporting reference: [12]
46. Extraction extent changes the bleeding-risk category
For patients taking anticoagulants or antiplatelet drugs, simple extraction of one to three teeth with restricted wound size sits in the low-risk category for postoperative bleeding complications, whereas complex extractions, adjacent extractions creating a large wound, or more than three extractions at once fall into the relatively higher-risk category, with the table serving as a guide requiring individual judgment about extent and invasiveness.
Worked example: A patient on clopidogrel needs two non-adjacent molar extractions, each with a small restricted socket; the plan is categorised as low risk of postoperative bleeding complications. When assessment shows one molar removal will be complex, the higher-risk category applies and management is judged accordingly.
Mistake to avoid: Counting teeth alone and placing three extractions in the low-risk category without checking whether the wounds are restricted or adjacent.
Supporting reference: [12]
47. Local infection measures and antibiotic indications
For dental bacterial infections, use local measures such as drainage of pus via the tooth or root canal in the first instance, and consider antibiotics only when there is a clinical indication, for example local measures proving ineffective, evidence of spreading infection or systemic involvement, or increased complication risk, always using antibiotics alongside rather than as a replacement for local measures.
Worked example: An adult presents with a periapical abscess and localized swelling; the tooth is extracted to drain the pus and analgesia advice given. When review shows spreading infection with fever, antibiotics are considered alongside continued local care, after checking interactions and contraindications.
Mistake to avoid: Issuing an antibiotic prescription instead of addressing the dental source, treating drugs as a routine substitute for local measures such as drainage.

48. Inflammatory dental pain is not an antibiotic indication
Antibiotics should not be prescribed to manage pain arising from inflammatory dental conditions such as irreversible pulpitis or dry socket after extractions, because this pain stems primarily from inflammation; instead, assessment should separate inflammatory pain from any coexisting infection that would provide an antibiotic indication, while appropriate local measures and analgesic assessment remain necessary, with no analgesic selection or dosing specified here.
Worked example: Assessment of a patient with severe pain five days after an extraction identifies a dry socket without spreading or systemic infection; no antibiotic is indicated, and care proceeds through local measures and analgesic assessment, without specifying particular drugs or doses.
Mistake to avoid: Using pain severity as evidence that antibiotics are needed, when severe inflammatory pain alone does not create an antibiotic indication.

49. Antibiotic review and safety netting
When antibiotics are indicated, record the diagnosis and prescribing reasons in the notes and give safety-netting advice to contact the practice if symptoms worsen rapidly or significantly, fail to improve, or new symptoms appear. Review patients ideally at three days, earlier if particularly unwell, preferably in person for severe infection. If systemic signs and symptoms have resolved at review, advise stopping the antibiotic.
Worked example: A patient prescribed antibiotics for a spreading dental infection is reviewed by phone at three days. Fever and malaise have settled and the swelling is improving, so the clinician reassesses and advises stopping the remaining course.
Mistake to avoid: Telling a patient to change or stop treatment simply because pain improves, without carrying out the stated reassessment at review.

50. Severe dental infection needs emergency escalation
Red-flag signs of severe or rapidly progressing spreading infection, including significant trismus, floor-of-mouth swelling, difficulty breathing or swallowing, rapidly spreading cellulitis, or deep or high-risk fascial-space involvement, require immediate emergency transfer to hospital. Where there is airway compromise, call 999 for an ambulance and provide any necessary emergency care. Immunocompromised patients warrant a lower threshold for escalation, and pre-transfer assessments should be recorded.
Worked example: A patient with dental swelling develops difficulty swallowing and increasing floor-of-mouth swelling during assessment. The clinician records observations and diagnosis, then arranges immediate emergency hospital transfer rather than prescribing antibiotics and reviewing as an outpatient.
Mistake to avoid: Prescribing an antibiotic and arranging routine follow-up for a patient with red-flag signs, allowing the prescription to delay emergency hospital transfer.

Medical emergency recognition and response
51. Call promptly when an adult is unresponsive
Under the 2025 adult basic life support guidance, call 999 as soon as possible for any unresponsive person, without first confirming abnormal breathing. Ideally a bystander calls, but a lone rescuer should make the call, then assess breathing while waiting for connection; the call handler can help with uncertainty. This adult guidance does not supply a paediatric algorithm.
Worked example: During a dental appointment a patient collapses and is unresponsive; the dental nurse, the only rescuer present, immediately starts a 999 call and assesses breathing while waiting for the call to be answered.
Mistake to avoid: Delaying the emergency call until abnormal breathing has been confirmed, instead of initiating the call first for any unresponsive adult.
Supporting reference: [14]
52. Unresponsiveness with abnormal breathing indicates presumed arrest
If an adult is unresponsive and breathing is abnormal, assume cardiac arrest and start chest compressions as soon as possible. Recognition can be difficult, and the ambulance call handler can assist when breathing assessment is uncertain. The 2025 guidance notes that breathing soon after an exercise-related arrest can appear near-normal or panting, so observed breathing movements do not exclude arrest.
Worked example: A collapsed adult in the waiting room is unresponsive with occasional gasping breaths. The rescuer treats this abnormal breathing as presumed cardiac arrest and starts chest compressions promptly while help is summoned.
Mistake to avoid: Assuming that any observed breathing movement excludes cardiac arrest, when abnormal or panting breathing can still occur during arrest.
Supporting reference: [14]
53. Adult chest-compression rate and depth
Adult basic life support guidelines specify a chest compression rate of 100 to 120 per minute with a depth of at least 5 cm but no more than 6 cm. These figures apply to adult casualties only, and knowing them from reading does not by itself demonstrate the practical compression skill assessed in manikin-based training.
Worked example: During a manikin drill, feedback shows compressions delivered at 110 per minute to a depth of 5.5 cm. Both values sit within the stated adult ranges, so the rescuer continues without adjusting rate or depth.
Mistake to avoid: Applying adult depth measurements to a child casualty, whose compression depth requirements differ from the adult minimum and maximum figures.
Supporting reference: [14]
54. Rescue breaths should produce visible chest rise
When rescue breaths are given during adult basic life support, each breath should deliver only enough air for the chest to start rising, because excessive ventilation can be harmful. If the chest cannot be ventilated at all, a foreign body airway obstruction should be considered rather than simply increasing the volume delivered.
Worked example: In a simulated adult scenario, a rescuer watches the chest just begin to rise and stops the breath there. When a later breath fails to move the chest, the team reassesses the airway for obstruction instead of blowing harder.
Mistake to avoid: Responding to failed ventilation by forcing larger breaths, which risks excessive ventilation while leaving a possible airway obstruction unaddressed.
Supporting reference: [14]
55. Anaphylaxis recognition and emergency escalation
Key signs of anaphylaxis include marked upper airway oedema and bronchospasm producing stridor and wheezing. Suspected anaphylaxis is an emergency requiring urgent hospital transfer by ambulance, and if cardiac arrest follows, basic life support should be started immediately with early defibrillation where a defibrillator is available.
Worked example: A patient develops stridor and wheezing during treatment, raising suspicion of anaphylaxis. The dental team calls an ambulance immediately for emergency hospital transfer and prepares to start basic life support with the defibrillator should cardiac arrest occur.
Mistake to avoid: Mistaking serious airway or breathing features such as stridor for a mild allergic reaction and delaying emergency ambulance escalation.

Managing safe dental practice
56. Decontamination roles require training and clarity
Decontamination guidance for primary care dental practices requires that all staff involved are suitably trained, with roles and responsibilities clearly defined and understood by everyone in the team. One person may hold several roles, but the practice must be able to demonstrate that each responsibility is assigned and understood.
Worked example: A small dental practice trains one employee to cover two decontamination roles, records both sets of responsibilities, and briefs the whole team so every member understands who holds each duty and how the arrangement is evidenced.
Mistake to avoid: Assuming a small team size removes the need for defined decontamination responsibilities, when demonstrable role allocation remains essential regardless of practice scale.

57. Maintenance and testing need evidence
Within HTM 01-05's primary care dental setting in England, a practice's decontamination system should be able to demonstrate, through documented records, that all relevant equipment maintenance and testing duties have been performed, and that professional advice has been obtained where necessary for equipment purchase, maintenance, testing and operation; no specific test frequency or acceptance value is supplied here.
Worked example: During an audit at an English dental practice, the registered manager asks to see the autoclave logbook, service records and periodic testing documentation rather than accepting verbal assurance that the machine has always worked normally, then notes any missing evidence for follow-up.
Mistake to avoid: Assuming that equipment switching on and completing cycles each day proves the required maintenance and testing were actually carried out and recorded.
Supporting reference: [4]
58. Delegation must specify decisions and actions
When managing a dental team, managers should ensure every member understands their role and responsibilities, including precisely which decisions and actions have been delegated to them and which have not; this clarity defines accountability but does not expand an individual's underlying competence or professional scope beyond what their training and registration permit.
Worked example: A principal dentist asks the practice manager to brief a newly qualified dental nurse on instrument processing, stating in writing that the nurse may decline damaged instruments but must refer any question about infection control policy to the dentist, who retains that decision.
Mistake to avoid: Telling a team member to help out in the surgery without stating which clinical decisions remain with the dentist.

59. Discussing new policies with the team
Managers should discuss all new policies and procedures with colleagues so that everybody understands them and all team members recognise their responsibility to comply; this is a communication and implementation duty, and discussion alone does not by itself establish that compliance is actually effective in daily practice.
Worked example: Before a practice introduces a revised instrument transport procedure between surgery and decontamination room, the manager gathers the dental nurses, walks through each step, invites questions, and confirms that each person understands they are personally responsible for following it.
Mistake to avoid: Emailing a new policy to the team and assuming that reading it, or filing it, guarantees genuine understanding and compliance.
Supporting reference: [3]
60. Checking team registration and indemnity
Managers should ensure relevant team members are appropriately registered with the GDC or another healthcare regulator, or are appropriately in training to be registered, and that those who are registered with the GDC are also indemnified; not every employee needs GDC registration, and these checks do not by themselves establish competence for any specific task.
Worked example: When a receptionist, a trainee dental nurse and a locum hygienist join the practice, the manager checks each person's status individually, confirming the trainee's in-training arrangement, the hygienist's GDC registration and indemnity, and recognising the receptionist needs no GDC registration.
Mistake to avoid: Assuming all staff share identical registration requirements, or that holding GDC registration alone proves competence in a particular task.
