Diploma in Primary Care Dentistry (DPCD) Overview
These study notes are designed to support candidates preparing for the Diploma in Primary Care Dentistry (DPCD) examination. The DPCD assesses the knowledge and skills required for safe, effective, and ethical practice in primary care dentistry in the UK. The notes are structured around six core subjects, each aligned with the General Dental Council (GDC) standards and the UK BDS curriculum. Candidates should use these notes alongside official GDC and RCS England resources and verify any specific exam details with the relevant awarding body.
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.

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.
- Clinical Assessment, Diagnosis, and Treatment Planning
- Restorative Dentistry and Endodontics
- Periodontology and Preventive Care
- Oral Surgery and Medical Emergencies
- Paediatric Dentistry and Orthodontics
- Professionalism, Ethics, and Practice Management
Exam Snapshot and Readiness Target
Format: The DPCD typically comprises written papers and clinical examinations. Practice formats on Dental Conquer include 80 questions in 120 minutes with a pass mark of 70%, but candidates should confirm the exact format with the examining body.
Candidate level: Entry-to-practice for dentists seeking registration in the UK, including overseas graduates.
Readiness target: Candidates should be ready to demonstrate competence in clinical assessment, diagnosis, treatment planning, and professional practice at the level of a UK BDS graduate.
Most candidates should budget at least 38+ focused study hours, then adjust upward for unfamiliar clinical systems, regulatory content, or specialty-level case reasoning.
Clinical Assessment, Diagnosis, and Treatment Planning
Syllabus Focus
- History taking and clinical examination
- Diagnostic tests and imaging interpretation
- Treatment planning and risk assessment
- Medical history and systemic disease considerations
Key Notes
- A systematic approach to history taking includes presenting complaint, dental history, medical history, social history, and drug history.
- Extraoral and intraoral examination should follow a consistent sequence: soft tissues, hard tissues, periodontium, occlusion, and function.
- Radiographic interpretation must consider anatomical landmarks, caries detection, periodontal bone loss, and pathology.
- Treatment planning prioritises emergency care, then disease control, then restorative/rehabilitative care, and finally maintenance.
- Risk assessment includes caries risk (low, moderate, high) and periodontal risk using tools like the Periodontal Risk Assessment (PRA).
- Medical history may require modification of dental treatment (e.g., antibiotic prophylaxis for certain cardiac conditions).
- Informed consent must be obtained after discussing diagnosis, treatment options, risks, benefits, and alternatives.
Must Know
- The GDC Standards for the Dental Team: principles of consent, communication, and record-keeping.
- Common oral lesions and their differential diagnoses (e.g., aphthous ulcers, lichen planus, leukoplakia).
- Interpretation of periapical, bitewing, and panoramic radiographs.
- The classification of caries (ICDAS, radiographic depth) and periodontal disease (staging and grading).
- The importance of vital signs and medical history in treatment planning.
Clinical and Exam Application
- When a patient presents with toothache, perform a systematic examination to differentiate between pulpal and periapical pathology.
- Use caries risk assessment to determine recall intervals and preventive interventions.
- For a patient with a history of infective endocarditis, consult the current guidelines for antibiotic prophylaxis before invasive procedures.
High-Yield Distinctions
- Caries vs. erosion: caries is a bacterial disease, erosion is chemical wear without bacteria.
- Pulpitis: reversible (pain on stimulus, resolves quickly) vs. irreversible (lingering pain, spontaneous).
- Periodontal abscess vs. periapical abscess: periodontal abscess originates from periodontium, periapical from pulp; treatment differs.
Common Pitfalls
- Failing to take a comprehensive medical history, leading to missed contraindications.
- Misinterpreting radiographic shadows as caries when they are cervical burnout or enamel hypoplasia.
- Overlooking extraoral examination (e.g., lymphadenopathy, swelling).
Review Tasks
- Practice taking a full history and examination on a peer, documenting findings.
- Review 10 periapical radiographs and identify caries, periapical pathology, and anatomical landmarks.
- Create a treatment plan for a patient with multiple carious lesions and moderate periodontitis.
Restorative Dentistry and Endodontics
Syllabus Focus
- Direct and indirect restorations
- Endodontic diagnosis and treatment
- Tooth preparation and materials science
- Crown, bridge, and implant prosthodontics
Key Notes
- Direct restorations (composite, amalgam) are placed directly in the cavity; indirect restorations (crowns, inlays) are fabricated externally.
- Endodontic treatment involves cleaning and shaping the root canal system, followed by obturation with gutta-percha and sealer.
- Tooth preparation for crowns requires reduction of occlusal, axial, and marginal surfaces to provide space for the restoration.
- Materials selection depends on aesthetic demands, strength requirements, and tooth location (e.g., composite for anterior, amalgam or ceramic for posterior).
- The principles of minimally invasive dentistry advocate preserving tooth structure whenever possible.
- Post-endodontic restoration: teeth with root canal treatment often require cuspal coverage to prevent fracture.
- Adhesive dentistry relies on bonding to enamel and dentin; moisture control is critical for success.
Must Know
- Classification of cavities (Black's classification) and cavity design principles.
- Steps of root canal treatment: access, working length determination, instrumentation, irrigation, obturation.
- Common causes of endodontic failure: missed canals, inadequate cleaning, coronal leakage.
- Indications for crown vs. filling: large restorations, cracked tooth, after root canal treatment.
- The role of fluoride in caries prevention and materials that release fluoride (e.g., glass ionomer).
Clinical and Exam Application
- For a deep carious lesion approaching the pulp, consider indirect pulp capping or stepwise excavation to avoid pulp exposure.
- When placing a composite restoration, use a total-etch or self-etch adhesive system according to manufacturer instructions.
- For a tooth with a fractured cusp, assess if a crown is needed based on remaining tooth structure and occlusal forces.
High-Yield Distinctions
- Amalgam vs. composite: amalgam has higher compressive strength and longevity, composite offers better aesthetics and adhesion.
- Gutta-percha vs. resilon: gutta-percha is the standard obturation material; resilon is a thermoplastic synthetic polymer.
- Open vs. closed sandwich technique: open sandwich uses glass ionomer as a base, closed sandwich covers it completely with composite.
Common Pitfalls
- Inadequate isolation during restorative procedures leading to contamination and bond failure.
- Over-instrumentation in endodontics causing perforation or weakening of the root.
- Placing a crown without adequate ferrule (2mm of vertical tooth structure) increases risk of fracture.
Review Tasks
- Draw and label the steps of a root canal treatment on an upper incisor.
- Compare and contrast the properties of composite, amalgam, and glass ionomer cement.
- Practice cavity preparation on a typodont for a class II amalgam and a class III composite.
Periodontology and Preventive Care
Syllabus Focus
- Periodontal anatomy and classification
- Gingivitis and periodontitis
- Non-surgical and surgical periodontal therapy
- Preventive strategies and oral hygiene instruction
Key Notes
- Periodontal disease is initiated by dental plaque biofilm; host response determines progression.
- Gingivitis is reversible inflammation of gingiva without attachment loss; periodontitis involves loss of connective tissue attachment and bone.
- The 2018 classification of periodontal diseases includes staging (severity) and grading (risk of progression).
- Non-surgical therapy (scaling and root planing) is the first-line treatment for periodontitis; surgical therapy may be needed for residual pockets.
- Preventive care includes plaque control, dietary advice, fluoride use, and regular recall intervals.
- Smoking is a major risk factor for periodontitis; cessation advice should be provided.
- Systemic conditions (e.g., diabetes) can influence periodontal health and treatment outcomes.
Must Know
- The components of a periodontal examination: probing depths, clinical attachment loss, bleeding on probing, furcation involvement, mobility.
- The difference between supragingival and subgingival calculus and their removal techniques.
- Indications for periodontal surgery: residual pockets >5mm after non-surgical therapy, furcation involvement, need for regenerative procedures.
- The role of chlorhexidine mouthwash as an adjunct to mechanical plaque control.
- Recall intervals based on risk assessment: 3-12 months.
Clinical and Exam Application
- For a patient with generalised chronic periodontitis, perform full-mouth scaling and root planing under local anaesthesia, followed by reassessment at 6-8 weeks.
- Provide tailored oral hygiene instruction: use of interdental brushes for sites with open embrasures, floss for tight contacts.
- For a diabetic patient with periodontitis, coordinate with their physician to optimise glycaemic control before and during treatment.
High-Yield Distinctions
- Chronic vs. aggressive periodontitis: chronic has slow progression, aggressive has rapid attachment loss and familial pattern (now replaced by staging/grading).
- Necrotising ulcerative gingivitis (NUG) vs. periodontitis: NUG presents with pain, pseudomembrane, and fetor oris; treatment includes debridement and metronidazole.
- Peri-implant mucositis vs. peri-implantitis: mucositis is reversible inflammation without bone loss; peri-implantitis involves bone loss.
Common Pitfalls
- Failing to record baseline probing depths, making it impossible to assess treatment outcomes.
- Overlooking the need for antimicrobial therapy in aggressive or refractory cases.
- Assuming that bleeding on probing is always due to inflammation; it can also be caused by trauma from probing.
Review Tasks
- Perform a periodontal examination on a typodont and record a full chart.
- Write a treatment plan for a patient with stage III, grade B periodontitis.
- Review the 2018 classification of periodontal diseases and apply it to clinical scenarios.
Oral Surgery and Medical Emergencies
Syllabus Focus
- Exodontia principles and techniques
- Complications of tooth extraction
- Medical emergencies in dental practice
- Management of oral pathology and trauma
Key Notes
- Exodontia involves careful assessment of tooth morphology, bone density, and proximity to vital structures.
- Simple extraction uses elevators and forceps; surgical extraction requires flap reflection and bone removal.
- Common complications include dry socket (alveolar osteitis), infection, haemorrhage, and nerve injury.
- Medical emergencies in dental practice: syncope, hypoglycaemia, anaphylaxis, cardiac arrest, seizures, and asthma attacks.
- The dental team must be trained in basic life support (BLS) and have emergency drugs and equipment available.
- Oral pathology includes cysts, tumours, and infections; biopsy may be needed for definitive diagnosis.
- Dental trauma management follows the IADT guidelines: avulsion, luxation, fracture.
Must Know
- The steps of a simple extraction: anaesthesia, elevation, forceps application, delivery, and post-operative instructions.
- Management of dry socket: irrigation, placement of a sedative dressing (e.g., Alvogyl), and analgesia.
- The contents of a dental emergency kit: oxygen, adrenaline, salbutamol, glucagon, aspirin, etc.
- Signs and symptoms of anaphylaxis: urticaria, angioedema, wheeze, hypotension; treatment: intramuscular adrenaline.
- The classification of odontogenic infections and their spread (e.g., buccal space, submandibular space).
Clinical and Exam Application
- When extracting a lower third molar, assess the relationship with the inferior alveolar nerve using a panoramic radiograph; consider CBCT if close.
- For a patient with a history of syncope, lay them flat, elevate legs, and ensure airway; if prolonged, consider other causes.
- In a case of avulsed permanent tooth, replant immediately or store in milk or saline, then splint for 2 weeks.
High-Yield Distinctions
- Dry socket vs. post-extraction infection: dry socket presents with severe pain 2-3 days post-op, no pus; infection has swelling, pus, and fever.
- Lingual nerve vs. inferior alveolar nerve injury: lingual nerve injury affects taste and sensation to anterior 2/3 of tongue; IAN injury affects lower lip and chin.
- Haemorrhage: primary (during surgery), reactionary (within hours), secondary (days later due to infection).
Common Pitfalls
- Failing to take a proper medical history, leading to missed anticoagulant use or other bleeding risks.
- Using excessive force during extraction causing root fracture or jaw fracture.
- Not recognising early signs of anaphylaxis and delaying adrenaline administration.
Review Tasks
- Practice the steps of a simple extraction on a typodont, including instrument selection.
- Create a flowchart for managing a medical emergency (e.g., anaphylaxis) in the dental clinic.
- Review the IADT guidelines for dental trauma and summarise management for avulsion.
Paediatric Dentistry and Orthodontics
Syllabus Focus
- Child development and behaviour management
- Paediatric caries and restorative options
- Growth and development of the dentition
- Orthodontic assessment and basic treatment principles
Key Notes
- Behaviour management techniques include tell-show-do, positive reinforcement, distraction, and in some cases, pharmacological methods.
- Paediatric caries (early childhood caries) is preventable with fluoride, diet advice, and oral hygiene.
- Restorative options for primary teeth: composite, glass ionomer, stainless steel crowns (SSC), and pulp therapy (pulpotomy, pulpectomy).
- The developing dentition: eruption sequence, mixed dentition period, and space management.
- Orthodontic assessment includes skeletal and dental relationships, overjet, overbite, crossbites, and crowding.
- Basic orthodontic appliances: removable appliances, fixed appliances, functional appliances, and retainers.
- The Index of Orthodontic Treatment Need (IOTN) is used to prioritise treatment based on dental health and aesthetic need.
Must Know
- The eruption dates of primary and permanent teeth.
- Indications for stainless steel crowns in primary molars: extensive caries, after pulp therapy, hypoplasia.
- The principles of space maintenance: when a primary tooth is lost prematurely, a space maintainer may be needed to prevent crowding.
- The classification of malocclusion (Angle's classification) and its clinical implications.
- The importance of fluoride varnish application in children at risk of caries.
Clinical and Exam Application
- For a 4-year-old with multiple carious primary molars, consider treatment under local anaesthesia with behaviour management; if uncooperative, refer for sedation or GA.
- When a 7-year-old presents with an anterior crossbite, assess if it is dental or skeletal; a simple removable appliance with a Z-spring may correct a dental crossbite.
- For a 12-year-old with crowding, refer for orthodontic assessment; extraction of premolars may be needed to create space.
High-Yield Distinctions
- Pulpotomy vs. pulpectomy in primary teeth: pulpotomy removes coronal pulp only (for reversible inflammation), pulpectomy removes all pulp (for irreversible inflammation).
- Primary vs. permanent tooth morphology: primary teeth are smaller, have thinner enamel, and more bulbous crowns.
- Functional appliances (e.g., Twin Block) vs. fixed appliances: functional appliances modify growth, fixed appliances move teeth in all dimensions.
Common Pitfalls
- Assuming a child will cooperate; always have a behaviour management plan and consider alternative approaches.
- Failing to diagnose a developing malocclusion early, missing the opportunity for interceptive treatment.
- Over-restoring primary teeth with composites that have higher failure rates than SSCs in high-caries-risk children.
Review Tasks
- Create a behaviour management plan for a 3-year-old requiring a simple restoration.
- Draw the eruption sequence of permanent teeth and note the age range for each.
- Practice taking an orthodontic assessment on a peer, including IOTN grading.
Professionalism, Ethics, and Practice Management
Syllabus Focus
- GDC Standards for the Dental Team
- Consent and confidentiality
- Complaints handling and record keeping
- Practice management and teamwork
Key Notes
- The GDC Standards for the Dental Team outline nine principles: put patients' interests first, communicate effectively, obtain valid consent, maintain and protect patients' information, have a clear and effective complaints procedure, work with colleagues in a way that is in patients' best interests, maintain, develop and work within your professional knowledge and skills, raise concerns if patients are at risk, and make sure your personal behaviour maintains patients' confidence in you and the dental profession.
- Valid consent requires the patient to be competent, informed, and giving consent voluntarily; it can be withdrawn at any time.
- Confidentiality must be maintained unless disclosure is required by law or necessary to protect the patient or others.
- Complaints should be handled promptly, fairly, and in accordance with the practice's complaints procedure; a written response should be provided.
- Accurate and contemporaneous record keeping is essential; records should include medical history, treatment provided, and communications.
- Practice management involves leadership, team working, financial management, and compliance with regulations (e.g., CQC, HSE).
- Dental professionals must engage in continuing professional development (CPD) to maintain competence.
Must Know
- The nine GDC standards and how they apply to everyday practice.
- The elements of valid consent: capacity, information, voluntariness.
- The Data Protection Act 2018 and GDPR requirements for patient records.
- The process for raising a concern about a colleague or patient safety (whistleblowing).
- The role of the Care Quality Commission (CQC) in regulating dental practices in England.
Clinical and Exam Application
- When a patient refuses a recommended treatment, document the discussion and respect their decision; ensure they understand the risks of not proceeding.
- If a patient discloses information that suggests they are at risk of harm, follow safeguarding protocols and disclose only with consent or if required by law.
- When a complaint is received, acknowledge it within 3 working days, investigate thoroughly, and provide a full response within 10 working days.
High-Yield Distinctions
- Ethical vs. legal obligations: ethical obligations may go beyond the law (e.g., going the extra mile for patient comfort).
- Duty of care vs. standard of care: duty of care is a legal obligation, standard of care is the level of competence expected.
- Confidentiality vs. disclosure: confidentiality is a duty, but disclosure may be justified in certain circumstances (e.g., public interest).
Common Pitfalls
- Assuming consent is implied; always obtain explicit consent for any treatment.
- Failing to document discussions about risks and alternatives, leading to allegations of lack of consent.
- Ignoring a complaint or handling it poorly, which can escalate to the GDC or Ombudsman.
Review Tasks
- Read the GDC Standards for the Dental Team and summarise each principle in your own words.
- Role-play a consent discussion for a complex treatment (e.g., extraction of a lower third molar).
- Review a sample complaints procedure and draft a response to a hypothetical complaint.
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
- Revisit the GDC Standards for the Dental Team and ensure you can apply each principle to clinical scenarios.
- Practice interpreting radiographs and identifying common pathologies.
- Review the classification systems for caries, periodontal disease, and malocclusion.
- Ensure you are familiar with the management of medical emergencies and the contents of the emergency kit.
- Consolidate your knowledge of paediatric dentistry, especially behaviour management and restorative options for primary teeth.
- Test yourself with timed practice papers to build speed and accuracy.
- Use the official sources listed below to verify any details not covered in these notes.
