8 weeks · About 7 hours per week
Operative Dentistry and Direct Restorations & Esthetic Dentistry and Materials Science
Map every Domain 2 and Domain 7 topic in the official exam blueprint to a one-line note on what you already know versus what you must learn

Solve 20 mixed operative and materials multiple-choice questions and write a short justification for every wrong option you rejected
Build a spaced-repetition deck of at least 40 cards covering cavity classification, matrix and wedge use, and material selection
Your checkpoint
A one-page materials selection table (material, indication, contraindication, key handling rule) plus a logged baseline score on 20 operative/materials questions
Operative Dentistry and Direct Restorations & Diagnosis and Treatment Planning
Work through the sequence of caries diagnosis and risk assessment, then state how risk level changes your restorative and preventive plan in three written clinical scenarios
Describe the steps for a Class II composite restoration, including proximal contour, contact creation, and matrix selection, in a numbered procedure list
Compare direct and indirect pulp capping and explain when each is chosen, citing the pulp diagnosis that justifies it
Complete 30 operative questions under timed conditions and review every error against a written reference
Your checkpoint
Three written case plans (high, moderate, and low caries risk) each with diagnosis, material choice, and preventive regimen
Endodontics & Diagnosis and Treatment Planning
Draw and label a pulpal and periapical diagnosis decision tree covering reversible and irreversible pulpitis, asymptomatic and symptomatic apical periodontitis, and pulp necrosis
Outline the access, working length determination, shaping, irrigation, and obturation sequence for a molar root canal treatment from memory
Explain the purpose, concentration, and safety precautions of the irrigants named in your reference material, including tissue toxicity and extrusion risk
Interpret 10 written endodontic case vignettes (symptoms, vitality test results, radiograph description) and commit to a diagnosis and treatment decision for each
List the indications for retreatment versus extraction and replacement in a previously treated tooth
Your checkpoint
A completed endodontic diagnosis and treatment decision flowchart plus 10 vignette answers scored against references
Periodontics & Diagnosis and Treatment Planning
Classify periodontal disease using the current staging and grading framework and apply it to five written patient profiles
Describe the components of a comprehensive periodontal examination, including probing depth, clinical attachment level, bleeding on probing, and radiographic bone assessment
Explain the rationale and expected outcomes of nonsurgical periodontal therapy and list the re-evaluation interval and criteria for referral for surgery
Summarize the evidence linking smoking, diabetes, and plaque control to periodontal outcomes
Answer 25 periodontics questions and record the reasoning behind each answer
Your checkpoint
Five staged and graded periodontal case summaries with a written nonsurgical treatment plan for each
Fixed and Removable Prosthodontics & Diagnosis and Treatment Planning
Compare tooth-supported, implant-supported, and removable prosthesis options for a single missing posterior tooth and state the deciding factors
List the principles of tooth preparation for a full-coverage crown, including taper, occlusal reduction, margin design, and ferrule, and explain why each matters
Describe the steps and records needed for a complete removable denture, from primary impression to review appointment
Explain occlusal scheme selection and the consequences of an unbalanced occlusion in fixed and removable prostheses
Work through 25 prosthodontics questions and write a one-line rationale for each correct answer
Your checkpoint
A two-page comparison matrix of treatment options for three prosthodontic scenarios (single posterior tooth, shortened arch, fully edentulous arch)
Implant Dentistry & Fixed and Removable Prosthodontics
Outline the implant treatment sequence from assessment and planning through surgery, healing, and restoration, naming the records required at each stage
Identify the patient, site, and loading factors that raise implant failure or peri-implant disease risk
Differentiate peri-implant mucositis from peri-implantitis and state the management approach for each
Explain the components and design features of an implant-supported crown or overdenture and how they affect retrievability and cleansability
Answer 20 implant questions and 10 prosthodontics questions, then review all errors
Your checkpoint
A written implant assessment checklist covering medical history, site assessment, radiographic planning, and maintenance schedule
Professionalism, Ethics, and Infection Control & Esthetic Dentistry and Materials Science
Apply the principles of informed consent, competence, and confidentiality to five written ethical dilemmas and justify each decision
State the current infection control requirements for hand hygiene, personal protective equipment, instrument reprocessing, and sharps handling, and identify common breaches in a written scenario
Explain the regulatory and professional obligations around record keeping and reporting of impaired colleagues or unsafe practice
Review shade selection, color science basics, and the esthetic parameters of smile design, and apply them to three written cases
Complete 25 mixed ethics, infection control, and esthetics questions and record your reasoning
Your checkpoint
A one-page infection control audit checklist plus written answers to five ethics vignettes
Diagnosis and Treatment Planning & Operative Dentistry and Direct Restorations & Endodontics & Periodontics & Fixed and Removable Prosthodontics & Implant Dentistry & Esthetic Dentistry and Materials Science & Professionalism, Ethics, and Infection Control
Re-run your baseline question set and compare scores domain by domain against week 1
Re-teach your three weakest domains aloud or in writing, using only a blank page
Complete two full-length timed practice papers under exam conditions and log every error by domain
Consolidate your spaced-repetition deck and retire cards you now answer correctly on first exposure
Write a one-page exam-day plan covering timing per question, flagging strategy, and review routine
Your checkpoint
A final score report by domain with a ranked list of residual weak areas and a written exam-day plan
Milestones
Week 2: You can state a caries risk level and justify a material choice for three cases without notes, and your timed operative score has improved over the week 1 baseline
Week 4: You can assign a periodontal stage and grade and reach a pulpal and periapical diagnosis from a written vignette in under two minutes each
Week 6: You can outline the full implant sequence and compare fixed versus removable options for a missing tooth, and your cumulative practice score across Domains 2-6 is at or above 65%
Week 8: Full-length timed papers are completed within the time limit, and no domain scores below 60% on the final by-domain report
