ADC Written Exam (Dental Hygiene) study plan

ADC Written Exam (Dental Hygiene) · Give each week a clear focus.

8 weeks · About 8 hours per week

Week 1

Biomedical sciences (anatomy, physiology, biochemistry, pathology, microbiology, pharmacology)

  • Map head and neck anatomy from memory: label cranial nerves, muscles of mastication, salivary glands, vascular supply and lymphatics on blank diagrams

  • Explain the physiology of mastication, swallowing, TMJ function and salivary secretion in short written summaries

  • Summarise the biochemistry of enamel and dentine mineralisation and describe how fluoride alters hydroxyapatite solubility

  • Build a spaced-repetition deck of at least 150 Domain 1 cards covering anatomy, physiology and biochemistry terms

Your checkpoint

Closed-book anatomy labelling sheet scored at least 85%, plus a 150-card deck built and reviewed twice

Week 2

Biomedical sciences (anatomy, physiology, biochemistry, pathology, microbiology, pharmacology)

  • Classify odontogenic cysts, odontogenic tumours and common mucosal lesions by origin, site and distinguishing features in a comparison table

  • Distinguish virulence factors, transmission routes and biofilm behaviour of key oral organisms including mutans streptococci, Porphyromonas gingivalis, Candida, HSV and hepatitis B

  • Summarise the drug classes used in dental practice (analgesics, antibiotics, local anaesthetics, vasoconstrictors, anticoagulants, bisphosphonates) with mechanism, typical dose range and relevant interactions

  • Work 60 vignette-style pathology and pharmacology items and log every error by cause

Your checkpoint

One-page drug summary table plus a 60-item vignette set scored at least 70% with a written error log

Week 3

Clinical dental sciences (restorative, endodontics, periodontics, prosthodontics, oral surgery, orthodontics, paediatric dentistry)

  • Sequence the steps and state the indications for direct and indirect restorations, and justify material selection against clinical variables

  • Outline endodontic diagnosis, pulp sensibility testing, working length determination, shaping and obturation, and the management of endodontic emergencies

  • Compare fixed and removable prosthodontic designs and explain tooth preparation, occlusal and hygiene principles for each

  • Answer 50 clinical case items on restorative, endodontic and prosthodontic decision-making

Your checkpoint

Three decision flowcharts (restorative material choice, endodontic protocol, prosthesis selection) plus 50 case items scored at least 70%

Week 4

Clinical dental sciences (restorative, endodontics, periodontics, prosthodontics, oral surgery, orthodontics, paediatric dentistry)

  • Stage and grade periodontal disease using the current classification and match each stage to a non-surgical or surgical treatment plan

  • Outline surgical protocols for routine and surgical extractions, flap design, impacted third molars, suturing and management of intra-operative and medical emergencies

  • Summarise orthodontic assessment, skeletal and dental classification basics, appliance types and the timing of referral

  • Apply behaviour management and preventive regimes in paediatric patients, covering fluoride varnish, fissure sealants, trauma and caries-risk recall intervals

Your checkpoint

A one-page periodontal staging cheat sheet plus a 30-item timed mixed Domain 2 block scored at least 75%

Week 5

Behavioural science, ethics and professionalism

  • Apply informed consent, capacity and confidentiality frameworks to ten written clinical scenarios and justify each decision

  • Distinguish autonomy, beneficence, non-maleficence, justice and veracity when resolving competing obligations in case vignettes

  • Explain scope of practice, registration and regulatory obligations, referral duties and mandatory reporting relevant to dental hygienists

  • Analyse behaviour-change models including the stages-of-change model and motivational interviewing as applied to non-adherent patients

Your checkpoint

Ten written ethics scenarios answered with principle-based justification, plus a one-page professionalism self-audit checklist

Week 6

Public health, prevention and dental practice management

  • Interpret epidemiological measures including prevalence, incidence, DMFT/dmft, sensitivity, specificity and number needed to treat from sample data sets

  • Design a community prevention programme with measurable targets, covering water fluoridation, school sealant schemes and tobacco-cessation referral

  • Outline infection prevention and control, waste handling, record-keeping and audit requirements for a dental practice

  • Compare practice management models for scheduling, recall systems, staffing, budgeting and ethical marketing

Your checkpoint

A one-page community prevention programme proposal with three measurable targets, plus a 40-item Domain 4 test scored at least 70%

Week 7

Biomedical sciences (anatomy, physiology, biochemistry, pathology, microbiology, pharmacology) & Clinical dental sciences (restorative, endodontics, periodontics, prosthodontics, oral surgery, orthodontics, paediatric dentistry)

  • Re-test the consolidated top-20 weak topics drawn from all four domains and close at least 15 of them

  • Work 80 mixed vignettes that link biomedical science directly to clinical decision-making

  • Rehearse dose, fluoride concentration and epidemiological calculations under timed conditions

  • Redraft summary sheets for anatomy, pathology, pharmacology and periodontics from memory, then correct them against source notes

Your checkpoint

A weak-topic tracker showing at least 15 of 20 topics closed, plus an 80-item mixed vignette score report

Week 8

Behavioural science, ethics and professionalism & Public health, prevention and dental practice management

  • Sit two full-length timed mock examinations under exam conditions covering all four domains

  • Categorise every incorrect answer by domain and by cause (knowledge gap, misread, calculation, guessing) and re-study each one

  • Recite one-page summary sheets for behavioural science, ethics, public health and practice management from memory

  • Finalise exam-day logistics and a 48-hour pre-exam review schedule

Your checkpoint

Two completed mock examinations averaging at least 75% with a domain-level score breakdown and error categorisation

Milestones

Week 2: Domain 1 self-test scored at least 70% and the anatomy, pathology and drug summary sheets are complete

Week 4: Domain 2 mixed block scored at least 75% and the periodontal staging and restorative flowcharts are finished

Week 6: All four domains covered with at least 70% on each domain test, and the error log condensed into a top-20 weak-topic list

Week 7: At least 15 of the top-20 weak topics closed and mixed vignette accuracy at or above 70%

Week 8: Two full mock examinations averaged at least 75% with no single domain below 65%
