NDEB Virtual OSCE (NDEB Equivalency Process) Overview

The NDEB Virtual OSCE is a case-based, decision-making examination that assesses clinical judgment, diagnosis, treatment planning, and patient management. It is part of the NDEB Equivalency Process for internationally trained dentists seeking licensure in Canada. The exam uses virtual patient scenarios to evaluate readiness for entry-to-practice. Candidates must integrate knowledge across all dental disciplines and demonstrate safe, evidence-based clinical reasoning.

For Dental Conquer practice planning, this module is tracked as 80 questions over about 120 minutes with a listed pass mark of 70%. Treat those numbers as practice baselines and verify the current official format before scheduling.

How This Guide Is Organized

The sections below turn the syllabus into studyable subject blocks. Read a subject first, explain the must-know ideas without notes, then use questions and flashcards to test whether the knowledge holds under pressure.

  • Patient Assessment and Diagnostic Interpretation
  • Comprehensive Treatment Planning and Case Management
  • Restorative Dentistry and Fixed/Removable Prosthodontics
  • Oral and Maxillofacial Surgery and Emergency Care
  • Endodontics and Periodontics

Exam Snapshot and Readiness Target

Format: Virtual, case-based, multiple-choice and short-answer questions; 80 questions in 120 minutes (practice baseline); pass mark approximately 70% (verify with NDEB).

Candidate level: Internationally trained dentists completing the NDEB Equivalency Process.

Readiness target: Entry-to-practice competence in clinical judgment, diagnosis, treatment planning, and patient management in a Canadian context.

Most candidates should budget at least 38+ focused study hours, then adjust upward for unfamiliar clinical systems, regulatory content, or specialty-level case reasoning.

Patient Assessment and Diagnostic Interpretation

Syllabus Focus

  • Medical and dental history taking
  • Extraoral and intraoral examination
  • Radiographic interpretation (panoramic, periapical, bitewing, CBCT basics)
  • Vital signs and systemic disease recognition
  • Diagnostic tests (pulp vitality, percussion, palpation, mobility)

Key Notes

  • Systematic approach: history, extraoral, intraoral, radiographs, special tests.
  • Recognize red flags: unexplained bleeding, rapid weight loss, trismus, lymphadenopathy.
  • Radiographic interpretation: identify caries, periodontal bone loss, periapical pathology, impacted teeth, sinus pathology, and anatomical landmarks.
  • Pulp testing: cold (most reliable), electric, and heat; false positives/negatives in multi-rooted teeth or recent trauma.
  • Periodontal probing: 6-point probing, bleeding on probing, furcation involvement, mobility grading.
  • Medical history: anticoagulants, bisphosphonates, immunosuppressants, pregnancy, allergies (latex, local anesthetic).
  • CBCT interpretation: limited to specific indications (e.g., implant planning, impacted canine localization, pathology assessment).

Must Know

  • Normal vs. abnormal findings: leukoplakia, erythroplakia, lichen planus, candidiasis, herpetic lesions.
  • Radiographic caries detection: proximal caries on bitewings, recurrent caries under restorations.
  • Periodontal disease classification: staging and grading (AAP/EFP 2018).
  • Pulp diagnosis: reversible vs. irreversible pulpitis, pulp necrosis, symptomatic vs. asymptomatic apical periodontitis.
  • Systemic conditions with oral manifestations: diabetes, HIV, autoimmune diseases, cardiovascular disease.

Clinical and Exam Application

  • Interpret a panoramic radiograph to identify impacted third molars, sinus pathology, and mandibular canal proximity.
  • Differentiate between periapical radiolucency (pulpal origin) and periodontal abscess (periodontal origin).
  • Assess a patient with a history of bisphosphonate use: plan for MRONJ risk reduction, consider alternative treatments.
  • Evaluate a patient with a bleeding disorder: consult physician, use local hemostatic agents, avoid NSAIDs.

High-Yield Distinctions

  • Reversible vs. irreversible pulpitis: reversible responds to cold with brief pain; irreversible has prolonged pain (>30 seconds).
  • Symptomatic apical periodontitis: pain on biting, percussion; asymptomatic: no pain, but radiolucency present.
  • Acute vs. chronic periodontitis: acute has rapid attachment loss, pain, suppuration; chronic is slow, often painless.
  • Primary vs. secondary herpetic gingivostomatitis: primary is severe, systemic symptoms; secondary is recurrent cold sores.
  • Leukoplakia vs. oral lichen planus: leukoplakia is a white patch that cannot be rubbed off, with malignant potential; lichen planus has reticular, erosive, or plaque-like forms, often bilateral.

Common Pitfalls

  • Overlooking medical history: e.g., anticoagulant use before extraction.
  • Misinterpreting radiographic artifacts: ghost images, superimposition, elongation/foreshortening.
  • Confusing periapical cyst with granuloma: both appear as radiolucencies; cyst has corticated border, granuloma may not.
  • Failing to perform pulp testing on teeth with large restorations or crowns.
  • Assuming all radiolucencies are carious: consider cervical burnout, Mach band effect, enamel hypoplasia.

Review Tasks

  • Practice systematic extraoral and intraoral examination on a partner or mannequin.
  • Review normal radiographic anatomy on panoramic and periapical radiographs.
  • Create a flowchart for differential diagnosis of oral ulcers.
  • Study the 2018 periodontal classification and apply to case scenarios.
  • Complete a mock patient assessment with history, exam, and radiograph interpretation.

Comprehensive Treatment Planning and Case Management

Syllabus Focus

  • Sequencing of treatment (phases: systemic, acute, disease control, definitive, maintenance)
  • Risk assessment (caries, periodontal, oral cancer)
  • Interdisciplinary treatment planning (ortho, perio, prosth, surgery)
  • Informed consent and ethical considerations
  • Referral and consultation protocols

Key Notes

  • Treatment phases: emergency/acute care → systemic disease stabilization → disease control (caries, perio) → definitive (restorative, prosth, surgery) → maintenance.
  • Caries risk assessment: low, moderate, high (based on diet, fluoride, saliva, past caries).
  • Periodontal risk assessment: bleeding, probing depths, furcation, smoking, diabetes.
  • Informed consent: discuss risks, benefits, alternatives; document thoroughly.
  • Ethical principles: autonomy, beneficence, non-maleficence, justice.
  • Referral criteria: complex cases (e.g., orthognathic surgery, implant placement, medically compromised).
  • Treatment plan modifications for special needs: anxiety, disabilities, pregnancy.

Must Know

  • Sequence for full-mouth rehabilitation: periodontal health → caries control → endo → crown lengthening → restorative → prosth.
  • When to extract vs. retain a tooth: strategic value, restorability, periodontal support, endodontic prognosis.
  • Antibiotic prophylaxis guidelines: AHA 2021 for infective endocarditis; AAOS for joint replacements (generally not recommended).
  • Management of medically compromised patients: diabetes (blood glucose control), hypertension (BP <180/110), anticoagulants (INR <4.0 for simple extractions).
  • Treatment planning for implant vs. fixed bridge vs. removable partial denture: consider bone volume, cost, patient preference, adjacent tooth status.

Clinical and Exam Application

  • Develop a phased treatment plan for a patient with rampant caries, chronic periodontitis, and a missing first molar.
  • Assess a patient with a history of head and neck radiation: high caries risk, osteoradionecrosis risk, need for fluoride trays and frequent recalls.
  • Plan for a patient with severe dental anxiety: consider sedation options, behavior management, and referral if needed.
  • Create a maintenance schedule for a periodontitis patient: 3-month recalls, probing, reinforcement of oral hygiene.

High-Yield Distinctions

  • Phase 1 (disease control) vs. Phase 2 (definitive): Phase 1 includes extractions, scaling, root planing, caries control; Phase 2 includes crowns, bridges, implants.
  • Caries risk: high-risk patients need fluoride varnish, chlorhexidine, dietary counseling, and shorter recall intervals.
  • Periodontal maintenance vs. supportive periodontal therapy: maintenance is for treated patients; SPT includes monitoring and re-treatment if needed.
  • Informed consent vs. implied consent: informed is written for major procedures; implied for routine exams.
  • Elective vs. emergency treatment: emergency treatment (pain, infection, trauma) takes priority over elective (cosmetic, elective implants).

Common Pitfalls

  • Proceeding with definitive restorations before controlling active disease (caries, perio).
  • Failing to consider systemic health: e.g., uncontrolled diabetes compromises periodontal treatment outcomes.
  • Inadequate informed consent: not discussing all options or risks leads to ethical and legal issues.
  • Overlooking patient financial constraints: treatment plan should include cost estimates and alternatives.
  • Not documenting treatment plan changes or patient refusal of recommended treatment.

Review Tasks

  • Practice writing a comprehensive treatment plan for a complex case (e.g., multiple missing teeth, perio disease).
  • Review the ADA Caries Risk Assessment form and apply to case scenarios.
  • Study the ethical principles and apply to dilemmas (e.g., patient refuses radiographs).
  • Create a checklist for informed consent documentation.
  • Simulate a treatment planning discussion with a patient (role-play).

Restorative Dentistry and Fixed/Removable Prosthodontics

Syllabus Focus

  • Direct restorations (amalgam, composite, glass ionomer)
  • Indirect restorations (inlay, onlay, crown, bridge)
  • Removable partial dentures (design, components, Kennedy classification)
  • Complete dentures (impression techniques, occlusion, post-insertion adjustments)
  • Implant prosthodontics (restorative options, abutment selection)

Key Notes

  • Amalgam: indications (posterior stress-bearing), contraindications (aesthetics, allergy), cavity preparation principles (resistance, retention, convenience form).
  • Composite: layering technique, curing depth (2mm), finishing and polishing, post-operative sensitivity management.
  • Glass ionomer: chemical bond to tooth, fluoride release, use in non-stress-bearing areas, cervical lesions, pediatric dentistry.
  • Indirect restorations: indications (large defects, cusp coverage), materials (ceramic, metal-ceramic, zirconia), cementation (resin vs. conventional).
  • Fixed bridge: abutment selection (crown-to-root ratio, periodontal health), pontic design (sanitary, ridge-lap, ovate), connectors.
  • RPD: Kennedy classification, direct/indirect retainers, major/minor connectors, rests, guiding planes.
  • Complete denture: border molding, secondary impression, jaw relation records, balanced occlusion, post-insertion adjustments (pressure spots, soreness).
  • Implant prosthodontics: single crown, fixed partial denture, overdenture; abutment types (stock, custom, angled); screw-retained vs. cement-retained.

Must Know

  • Cavity preparation principles: outline form, resistance form, retention form, convenience form, removal of remaining carious dentin.
  • Ferrule effect: 1.5-2mm of vertical tooth structure for crown retention.
  • Abutment selection for fixed bridge: favorable crown-to-root ratio (≥1:1), minimal mobility, healthy periodontium.
  • Kennedy Class I: bilateral distal extension; Class II: unilateral distal extension; Class III: unilateral bounded edentulous area; Class IV: anterior bounded edentulous area crossing midline.
  • Implant loading protocols: immediate (within 48h), early (6-8 weeks), conventional (3-6 months).

Clinical and Exam Application

  • Select restorative material for a Class II lesion in a premolar: composite for aesthetics, amalgam for durability if occlusion is heavy.
  • Design an RPD for Kennedy Class I: consider stress distribution, indirect retention, and base extension.
  • Plan a crown for an endodontically treated molar: consider post and core if insufficient tooth structure, ferrule, and crown material (zirconia or metal-ceramic).
  • Troubleshoot a complete denture with poor retention: check border extension, peripheral seal, and occlusion.

High-Yield Distinctions

  • Amalgam vs. composite: amalgam has higher compressive strength, less technique sensitivity; composite has better aesthetics, bonds to tooth.
  • Inlay vs. onlay: inlay does not cover cusps; onlay covers one or more cusps for protection.
  • Screw-retained vs. cement-retained implant crown: screw-retained retrievable, no cement remnants; cement-retained better aesthetics, but risk of peri-implantitis from excess cement.
  • RPD direct retainer: intracoronal (precision attachment) vs. extracoronal (clasp); clasp types: circumferential, bar (T, I, L).
  • Complete denture occlusion: balanced occlusion (bilateral contacts in excursive movements) vs. canine guidance (not typically used in complete dentures).

Common Pitfalls

  • Inadequate ferrule: crown fracture or debonding.
  • Overpreparation of tooth for crown: pulp exposure or weakened tooth.
  • RPD design errors: inadequate indirect retention, poor major connector fit, impinging on gingiva.
  • Complete denture: overextended borders causing soreness, underextended borders causing poor retention.
  • Implant crown: cement remnants causing peri-implantitis; screw loosening due to improper torque.

Review Tasks

  • Practice cavity preparation on typodonts for Class I, II, III, V.
  • Design RPDs for different Kennedy classes using a surveyor.
  • Review complete denture impression techniques (open-mouth vs. closed-mouth).
  • Study implant restorative components and torque values.
  • Create a table comparing restorative materials (indications, contraindications, properties).

Oral and Maxillofacial Surgery and Emergency Care

Syllabus Focus

  • Exodontia (simple and surgical extractions)
  • Impacted teeth (third molars, canines)
  • Odontogenic infections (space infections, management)
  • Trauma (dentoalveolar fractures, mandible fractures, soft tissue injuries)
  • Pre-prosthetic surgery (alveoloplasty, tori removal, vestibuloplasty)
  • Emergency management (airway obstruction, anaphylaxis, syncope, hypoglycemia)

Key Notes

  • Simple extraction: forceps technique, luxation, controlled force; avoid root fracture.
  • Surgical extraction: flap design (envelope, triangular), bone removal (bur, osteotome), sectioning of tooth.
  • Impacted third molars: classification (Pell & Gregory, Winter's lines), indications for removal (pathology, pericoronitis, caries, orthodontic), risks (IAN injury, sinus exposure).
  • Odontogenic infections: spread via fascial spaces (canine, buccal, submandibular, sublingual, pterygomandibular, lateral pharyngeal, retropharyngeal); airway compromise is a medical emergency.
  • Dentoalveolar trauma: Ellis classification (enamel, dentin, pulp), luxation (concussion, subluxation, extrusion, lateral luxation, intrusion), avulsion (replantation protocol).
  • Mandible fractures: most common sites (condyle, angle, body, symphysis); signs (malocclusion, step deformity, paresthesia).
  • Pre-prosthetic surgery: alveoloplasty for ridge smoothing, tori removal, vestibuloplasty for sulcus deepening.
  • Emergency care: syncope (Trendelenburg position, oxygen), anaphylaxis (epinephrine IM, call 911), hypoglycemia (oral glucose if conscious, IV dextrose if unconscious).

Must Know

  • Inferior alveolar nerve block: landmarks (pterygomandibular raphe, coronoid notch), complications (hematoma, paresthesia, intravascular injection).
  • Pericoronitis: management (irrigation, antibiotics if systemic signs, extraction of offending tooth).
  • Dry socket (alveolar osteitis): etiology (loss of clot), treatment (irrigation, sedative dressing like eugenol).
  • Avulsion: replant within 30 minutes, store in milk or saline, splint for 7-10 days, root canal treatment after 7-10 days.
  • Antibiotic prophylaxis for infective endocarditis: amoxicillin 2g PO 1 hour before procedure; alternatives: clindamycin, cephalexin.

Clinical and Exam Application

  • Manage a patient with a spreading odontogenic infection: assess airway, IV antibiotics, incision and drainage, extraction of source.
  • Treat a patient with a fractured mandible: refer to oral surgeon, stabilize with arch bars or IMF, monitor airway.
  • Replant an avulsed permanent incisor: clean with saline, replant, splint, prescribe antibiotics, arrange endodontic follow-up.
  • Handle a syncopal episode in the dental chair: recognize prodrome (sweating, pallor), lower head, oxygen, ammonia inhalant if needed.

High-Yield Distinctions

  • Simple vs. surgical extraction: simple uses forceps only; surgical requires flap and bone removal.
  • Pell & Gregory classification: Class I (no bone impaction), II (partial bone), III (complete bone); Position A (above occlusal plane), B (at occlusal plane), C (below occlusal plane).
  • Odontogenic vs. non-odontogenic infections: odontogenic originate from tooth pulp/perio; non-odontogenic from salivary glands, sinuses, etc.
  • Ellis Class I (enamel only) vs. II (enamel and dentin) vs. III (enamel, dentin, pulp): treatment varies from smoothing to pulp therapy.
  • Luxation vs. avulsion: luxation is displacement within socket; avulsion is complete displacement out of socket.

Common Pitfalls

  • Root fracture during extraction: use elevators, section tooth, avoid excessive force.
  • IAN injury during third molar extraction: avoid apical pressure, use proper technique, warn patient preoperatively.
  • Missed space infection: patient presents with trismus, fever, swelling; need immediate referral.
  • Inadequate splinting of avulsed tooth: flexible splint for 7-10 days; rigid splint can cause ankylosis.
  • Failure to recognize medical emergency: e.g., anaphylaxis mistaken for syncope.

Review Tasks

  • Practice extraction techniques on simulation models.
  • Review anatomy of fascial spaces and spread of infection.
  • Study the dental trauma guidelines (IADT).
  • Create a flowchart for emergency management (syncope, anaphylaxis, hypoglycemia, seizure).
  • Complete a mock surgical extraction case: assess radiograph, plan flap, section tooth, close.

Endodontics and Periodontics

Syllabus Focus

  • Endodontic diagnosis and treatment planning
  • Root canal anatomy and access cavity preparation
  • Cleaning and shaping (instrumentation, irrigation)
  • Obturation techniques
  • Endodontic retreatment and surgery (apicoectomy)
  • Periodontal diagnosis (staging and grading)
  • Non-surgical periodontal therapy (scaling and root planing)
  • Periodontal surgery (flap surgery, regenerative procedures, crown lengthening)

Key Notes

  • Endodontic diagnosis: pulp tests (cold, EPT, heat), percussion, palpation, mobility, radiographic assessment.
  • Access cavity: straight-line access to canal orifices; remove all pulp chamber roof; locate all canals (use magnification, troughing).
  • Cleaning and shaping: crown-down or step-back technique; apical preparation size (at least #25, 0.04 taper); irrigation with NaOCl (1-5.25%), EDTA, chlorhexidine.
  • Obturation: gutta-percha with sealer (AH Plus, bioceramic); techniques: cold lateral compaction, warm vertical compaction, carrier-based.
  • Retreatment: remove existing filling, re-instrument, irrigate, obturate; consider surgery if non-surgical fails.
  • Periodontal diagnosis: staging (I-IV based on severity and complexity) and grading (A-C based on progression rate).
  • Non-surgical therapy: scaling and root planing (SRP) with hand or ultrasonic instruments; 6-8 weeks re-evaluation.
  • Periodontal surgery: flap for access (modified Widman, apically positioned), regenerative (GTR, bone grafts), resective (osseous surgery), crown lengthening.

Must Know

  • Root canal anatomy: maxillary first molar (3 canals, MB2 common), mandibular first molar (2 canals, sometimes 3), maxillary premolars (2 canals common).
  • Working length determination: electronic apex locator (preferred), radiograph (file 0.5-1mm short of apex).
  • Irrigation protocol: NaOCl (tissue dissolution, antimicrobial), EDTA (smear layer removal), final rinse with NaOCl or chlorhexidine.
  • Periodontal probing: 6 sites per tooth; normal ≤3mm; bleeding on probing indicates inflammation.
  • Crown lengthening: indications (subgingival caries, short clinical crown, ferrule); amount of bone removal (3mm supracrestal tissue attachment).

Clinical and Exam Application

  • Diagnose and treat a patient with symptomatic irreversible pulpitis: access, clean, shape, obturate in one or two visits.
  • Manage a perio-endo lesion: determine primary source; if endo, perform RCT; if perio, perform SRP; if combined, both.
  • Perform scaling and root planing on a patient with chronic periodontitis: use ultrasonic and hand instruments, local anesthesia if needed.
  • Plan crown lengthening for a tooth with subgingival caries: assess bone levels, perform flap surgery, remove bone, suture.

High-Yield Distinctions

  • Reversible vs. irreversible pulpitis: reversible responds to cold with brief pain; irreversible has prolonged pain.
  • Pulp necrosis vs. apical periodontitis: necrosis is non-vital pulp; apical periodontitis is inflammation of periapical tissues (may be symptomatic or asymptomatic).
  • Chronic vs. aggressive periodontitis: chronic is slow progression, plaque-associated; aggressive is rapid, familial, minimal plaque.
  • GTR vs. bone graft: GTR uses membrane to exclude epithelium; bone graft provides scaffold for bone formation; often combined.
  • Perio-endo lesion: primary endo has deep probing on one surface, pulp non-vital; primary perio has generalized probing, pulp vital.

Common Pitfalls

  • Missed canals: especially MB2 in maxillary molars, second canal in mandibular incisors.
  • Overinstrumentation: pushing debris beyond apex, causing postoperative pain or sinus tract.
  • Inadequate irrigation: failure to remove smear layer or disinfect lateral canals.
  • Incomplete SRP: residual calculus leads to persistent inflammation.
  • Crown lengthening: insufficient bone removal leads to biologic width violation and gingival inflammation.

Review Tasks

  • Practice access cavity preparation on extracted teeth or 3D models.
  • Review root canal anatomy using CBCT or anatomical diagrams.
  • Perform SRP on a typodont with calculus simulation.
  • Study perio-endo lesion classification and treatment algorithms.
  • Complete a mock endodontic case: diagnose, plan access, determine working length, obturate.

Pediatric Dentistry and Orthodontic Assessment

Syllabus Focus

  • Growth and development (dental eruption, occlusion development)
  • Caries risk assessment and prevention in children
  • Restorative treatment for primary teeth
  • Pulp therapy in primary teeth (pulpotomy, pulpectomy)
  • Behavior management (non-pharmacological, sedation, GA)
  • Orthodontic assessment (malocclusion classification, space analysis, treatment timing)
  • Common orthodontic appliances (fixed, removable, functional)
  • Management of dental trauma in children

Key Notes

  • Primary tooth eruption: incisors (6-12 months), canines (16-20 months), molars (12-30 months); exfoliation: incisors (6-7 years), canines (9-12 years), molars (10-12 years).
  • Caries risk: high-risk children need fluoride varnish every 3-6 months, sealants, dietary counseling, and frequent recalls.
  • Restorative materials for primary teeth: glass ionomer (low caries risk, non-stress areas), composite (aesthetics), stainless steel crowns (multi-surface caries, high risk).
  • Pulp therapy: pulpotomy (formocresol, ferric sulfate, MTA) for reversible pulpitis; pulpectomy for irreversible pulpitis or necrosis.
  • Behavior management: tell-show-do, positive reinforcement, distraction, parental presence, sedation (nitrous oxide, oral), general anesthesia.
  • Orthodontic assessment: Angle classification (Class I, II, III), overjet, overbite, crossbite, crowding, spacing.
  • Space analysis: mixed dentition analysis (Nance, Moyers) to predict crowding.
  • Treatment timing: early treatment (interceptive) for crossbites, habits, space maintenance; comprehensive treatment usually in adolescence.

Must Know

  • Stainless steel crown (SSC) indications: multi-surface caries, after pulpotomy, hypoplasia, high caries risk.
  • Pulpotomy vs. pulpectomy: pulpotomy removes coronal pulp only; pulpectomy removes all pulp tissue.
  • Space maintainer indications: premature loss of primary second molar (band and loop), primary first molar (distal shoe if first permanent molar erupted).
  • Angle classification: Class I (normal molar relationship), Class II (mandibular molar distal to maxillary), Class III (mandibular molar mesial).
  • Habit management: thumb sucking (if persists beyond age 4, consider appliance like palatal crib).

Clinical and Exam Application

  • Place an SSC on a primary molar: select size, trim, cement with glass ionomer.
  • Perform a pulpotomy on a primary molar: remove coronal pulp, apply medicament (e.g., ferric sulfate), place SSC.
  • Assess a 7-year-old with anterior crossbite: consider early intervention with inclined plane or tongue blade.
  • Manage an avulsed permanent incisor in a 10-year-old: replant, splint, monitor for pulp necrosis.

High-Yield Distinctions

  • Primary vs. permanent tooth morphology: primary teeth have thinner enamel, larger pulp chambers, more bulbous crowns.
  • Pulpotomy agents: formocresol (historical, controversial), ferric sulfate (hemostatic), MTA (biocompatible, promotes healing).
  • Space maintainer: fixed (band and loop, lingual arch) vs. removable (partial denture).
  • Class II division 1 vs. division 2: division 1 has increased overjet, protruding maxillary incisors; division 2 has retroclined maxillary central incisors.
  • Early vs. late orthodontic treatment: early (interceptive) addresses skeletal issues; late (comprehensive) aligns teeth.

Common Pitfalls

  • Underestimating caries risk in children: high-risk children need aggressive prevention.
  • Incorrect SSC size: too large causes gingival irritation; too small does not seat fully.
  • Pulpotomy failure: improper diagnosis (should be reversible pulpitis), inadequate hemorrhage control.
  • Space maintainer: failure to monitor can lead to loss of space or appliance damage.
  • Orthodontic assessment: ignoring skeletal discrepancies (need for functional appliance or surgery).

Review Tasks

  • Practice SSC preparation and cementation on a typodont.
  • Review pulpotomy technique and medicaments.
  • Study eruption sequence and exfoliation times.
  • Perform mixed dentition space analysis on a study model.
  • Create a flowchart for management of dental trauma in children.

How To Use These Notes With Practice Questions

Do not jump straight from reading to a full mock. Work by subject first: review the key notes, make a short recall sheet from memory, then answer a focused question set. After each miss, decide whether the problem was missing knowledge, poor clinical sequencing, weak source-rule recall, or a distractor you failed to eliminate.

Dental Conquer's question bank, flashcards, mind maps, and spaced review tools are most useful after this instruction layer because they reveal which parts of the notes are not yet retrievable.

Final Review Checklist
