Australian Dental Council Practical Examination (ADC Practical) Overview
These study notes are designed to help candidates prepare for the Australian Dental Council (ADC) Practical Examination, an entry-to-practice assessment for dentists seeking registration in Australia. The notes cover six core subject areas based on the ADC competency framework, with a focus on clinical skills, communication, and professional standards. Candidates should supplement these notes with the official ADC handbooks and materials.
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.

Format: Practical examination with multiple stations assessing clinical skills, communication, and diagnosis. The practice baseline on Dental Conquer is 80 questions in 120 minutes with a pass mark of 70%; candidates should verify the official format and pass mark with the ADC.
Candidate level: Entry-to-practice for dental licensure in Australia.
Readiness target: Candidates should be able to demonstrate competence in restorative, endodontic, and prosthodontic procedures, as well as patient management, diagnostic reasoning, and infection control.
Most candidates should budget at least 38+ focused study hours, then adjust upward for unfamiliar clinical systems, regulatory content, or specialty-level case reasoning.
Restorative Clinical Technical Skills
Syllabus Focus
- Cavity preparation and restoration for various tooth surfaces
- Selection and manipulation of restorative materials (amalgam, composite, glass ionomer)
- Matrix and wedge placement
- Caries removal and pulp protection
Key Notes
- Cavity preparation must follow Black's principles: outline form, resistance form, retention form, convenience form, and removal of remaining carious dentin.
- For composite restorations, use a total-etch or self-etch adhesive system; apply in increments to minimize polymerization shrinkage.
- Amalgam requires adequate condensation and carving; avoid moisture contamination during placement.
- Glass ionomer cement bonds chemically to tooth structure and releases fluoride; use for non-load-bearing areas or as a base.
- Pulp protection: use calcium hydroxide liner for deep cavities, resin-modified glass ionomer for moderate depth.
Must Know
- Class I to V cavity classifications and their specific preparation features.
- Indications and contraindications for amalgam vs. composite vs. glass ionomer.
- Proper use of rubber dam isolation for restorative procedures.
- Techniques for achieving proximal contact and contour.
Clinical and Exam Application
- Restoring a carious lesion on a posterior tooth: select material based on size, location, and occlusal load.
- Managing a deep carious lesion: apply liner, base, and restoration in sequence.
- Replacing a failed restoration: assess reason for failure, remove defective material, and prepare new cavity.
High-Yield Distinctions
- Composite requires etching and bonding; amalgam relies on mechanical retention.
- Glass ionomer has lower wear resistance than composite or amalgam.
- Amalgam bonding (using adhesive systems) can improve retention but is not always indicated.
Common Pitfalls
- Inadequate isolation leading to moisture contamination and restoration failure.
- Overhanging margins from improper matrix adaptation.
- Insufficient curing time for composite leading to incomplete polymerization.
Review Tasks
- Practice cavity preparation on typodont teeth for all classes.
- Review manufacturer instructions for common restorative materials.
- Study pulp protection protocols and liner placement techniques.
Endodontic Technical Procedures
Syllabus Focus
- Access cavity preparation
- Root canal instrumentation and irrigation
- Obturation techniques
- Management of endodontic emergencies
Key Notes
- Access cavity must provide straight-line access to the canal orifices; remove all pulp chamber roof and debris.
- Use a systematic approach to locate canals: follow pulp chamber floor anatomy and use magnification if needed.
- Irrigation with sodium hypochlorite (0.5-5.25%) is essential for disinfection; use EDTA for smear layer removal.
- Obturation with gutta-percha and sealer using cold lateral condensation or warm vertical compaction.
- Working length determination: use electronic apex locator and confirm with radiograph.
Must Know
- Root canal anatomy of each tooth type (number of canals, curvature, length).
- Step-back or crown-down instrumentation techniques.
- Signs of vertical root fracture and how to differentiate from periodontal disease.
- Emergency management: pulpotomy, pulpectomy, or incision and drainage for acute apical abscess.
Clinical and Exam Application
- Performing root canal treatment on a mandibular first molar with two mesial and one distal canal.
- Managing a patient with irreversible pulpitis: access, extirpate pulp, and place temporary restoration.
- Retreating a failed root canal: remove existing filling, re-instrument, and obturate.
High-Yield Distinctions
- Sodium hypochlorite is the primary irrigant; chlorhexidine is an alternative but does not dissolve tissue.
- Warm vertical compaction provides a denser fill than cold lateral condensation.
- Mineral trioxide aggregate (MTA) is used for apexification, perforation repair, and pulp capping.
Common Pitfalls
- Missed canals due to inadequate access or failure to explore pulp chamber floor.
- Ledging or transportation of the canal during instrumentation.
- Overfilling or underfilling the root canal system.
Review Tasks
- Practice access cavity preparation on extracted teeth or typodonts.
- Review radiographic interpretation of root canal anatomy and obturation quality.
- Study irrigation protocols and their sequence.
Fixed Prosthodontics and Preparations
Syllabus Focus
- Tooth preparation for crowns and bridges
- Impression techniques
- Provisional restoration fabrication
- Crown and bridge cementation
Key Notes
- Full crown preparation: reduce occlusal surface by 1.5-2 mm, axial walls by 1-1.5 mm, with a chamfer or shoulder margin.
- For metal-ceramic crowns, provide adequate reduction for metal coping and porcelain veneer.
- Impression materials: polyvinyl siloxane (addition silicone) or polyether; use a two-step or single-step technique.
- Provisional restorations must maintain occlusal contacts, proximal contacts, and gingival health.
- Cementation: use resin cement for high-strength ceramics, glass ionomer for metal crowns.
Must Know
- Principles of tooth preparation: retention and resistance form, preservation of tooth structure, margin placement.
- Indications for different crown types (full metal, PFM, all-ceramic, zirconia).
- Techniques for achieving accurate impressions: retraction cord, proper tray selection.
- Criteria for bridge design: abutment selection, pontic design, connector size.
Clinical and Exam Application
- Preparing a maxillary central incisor for an all-ceramic crown: ensure adequate incisal reduction and smooth margins.
- Taking an impression for a three-unit bridge: use a custom tray and heavy-body/light-body combination.

High-Yield Distinctions
- Zirconia requires more reduction than lithium disilicate due to opacity.
- Resin cement provides higher bond strength but requires meticulous moisture control.
- Porcelain-fused-to-metal (PFM) crowns have a metal substructure for strength and porcelain for aesthetics.
Common Pitfalls
- Under-reduction leading to inadequate thickness for restoration material.
- Over-reduction compromising pulp vitality.

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.

- Review all subject keyNotes and mustKnow items systematically.
- Practice clinical skills on typodonts or simulated patients under timed conditions.
- Review official ADC handbooks and materials for detailed competency statements.
- Focus on high-yield distinctions and common pitfalls to avoid errors.
- Simulate exam stations with peers to improve communication and time management.
