NZDREX study plan

NZDREX · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

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

  • List the direct restorative materials named in the blueprint (amalgam, composite, glass ionomer, resin-modified glass ionomer, compomer) and write the indications, contraindications, and setting mechanism for each from memory

  • Explain the enamel and dentine bonding mechanism step by step, including smear layer, etching, primer, and adhesive interactions, without notes

  • 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

Week 2

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

Week 3

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

Week 4

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

Week 5

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)

Week 6

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

Week 7

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

Week 8

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
