Advanced Oral Diagnosis and Pathological Assessment
Syllabus Focus
- Oral and maxillofacial pathology
- Diagnostic imaging interpretation
- Clinical and histopathological correlation
- Systemic disease oral manifestations
Key Notes
- Recognize common oral lesions (e.g., leukoplakia, erythroplakia, lichen planus) and their malignant potential.
- Understand biopsy techniques: incisional vs. excisional, and when to use each.
- Interpret panoramic and CBCT findings for pathology, including radiolucent/radiopaque lesions.
- Correlate clinical presentation with histopathology for definitive diagnosis.
- Identify oral manifestations of systemic diseases (e.g., diabetes, HIV, autoimmune disorders).
- Use diagnostic adjuncts like vital staining, brush biopsy, and salivary diagnostics appropriately.
Must Know
- WHO classification of odontogenic tumors and cysts.
- Diagnostic criteria for oral squamous cell carcinoma and its precursors.
- Radiographic features of common jaw pathologies (e.g., ameloblastoma, OKC, cementoblastoma).
- Differential diagnosis for red and white lesions of the oral mucosa.
Clinical and Exam Application
- When a patient presents with a non-healing ulcer, perform a thorough history and biopsy.
- Use CBCT to assess the extent of a radiolucent lesion before surgical planning.
- Differentiate between periapical cyst and granuloma using radiographs and histology.
High-Yield Distinctions
- Odontogenic keratocyst (OKC) vs. dentigerous cyst: OKC has higher recurrence, requires aggressive enucleation.
- Ameloblastoma vs. Pindborg tumor: ameloblastoma is locally invasive; Pindborg tumor has calcifications.
- Squamous cell carcinoma vs. verrucous carcinoma: verrucous has better prognosis, less metastasis.
Common Pitfalls
- Misdiagnosing a periapical cyst as a granuloma without histology.
- Overlooking systemic causes of oral lesions (e.g., lupus, Crohn's disease).
- Failing to consider malignancy in persistent ulcers, especially in smokers.
Review Tasks
- Review the WHO classification of odontogenic tumors.
- Practice interpreting 10 panoramic radiographs with pathology.
- Create a flowchart for differential diagnosis of oral ulcers.
Comprehensive Treatment Planning and Interdisciplinary Coordination
Syllabus Focus
- Sequencing of multidisciplinary care

- Case complexity evaluation
- Communication with referring providers
Key Notes
- Develop a problem list and prioritize treatment based on urgency and patient needs.
- Assess periodontal, restorative, endodontic, and surgical factors before finalizing plan.
- Use prognostic indices (e.g., tooth retention, periodontal staging) to guide decisions.
- Coordinate with specialists: orthodontics, prosthodontics, oral surgery, etc.
- Document treatment options with risks, benefits, and alternatives for informed consent.
- Consider systemic health, medications, and social factors in planning.
Must Know
- Periodontal disease classification (staging and grading).
- Tooth prognosis classification (e.g., good, fair, poor, hopeless).
- Principles of implant treatment planning (bone volume, sinus lift, nerve proximity).
- Interdisciplinary sequencing: periodontics first, then ortho, then restorative.
Clinical and Exam Application
- For a patient with severe periodontitis and missing teeth, plan initial non-surgical therapy, then evaluate for implants.
- Coordinate with orthodontist for forced eruption of a fractured tooth before restoration.
- Use CBCT to assess sinus anatomy before sinus lift procedure.
High-Yield Distinctions
- Periodontal vs. periapical abscess: periodontal has pocket, periapical has necrotic pulp.
- Implant vs. fixed bridge: implant preserves adjacent teeth, bridge requires tooth reduction.
- Extraction vs. root canal: consider restorability, bone support, and patient preference.
Common Pitfalls
- Proceeding with implants without adequate bone assessment.
- Ignoring periodontal disease before restorative treatment.
- Failing to communicate with referring dentist, leading to conflicting plans.
Review Tasks
- Review the periodontal disease classification system.

- Be aware of bisphosphonate-related osteonecrosis of the jaw (BRONJ) risk.
Must Know
- Antibiotic regimens for odontogenic infections (amoxicillin, clindamycin alternatives).
- Local anesthetic maximum doses: lidocaine 4.4 mg/kg, articaine 7 mg/kg.
- Drug interactions: NSAIDs with warfarin, metronidazole with alcohol.
- Medical emergencies: syncope, allergic reaction, hypoglycemia, seizure management.
Clinical and Exam Application
- For a patient with prosthetic heart valve, prescribe amoxicillin 2g 30-60 min before procedure.
- For a patient on warfarin with INR 3.0, postpone elective surgery until INR ≤ 2.5.
- For a patient with history of BRONJ, avoid extraction and consider conservative treatment.
High-Yield Distinctions
- Amoxicillin vs. clindamycin: amoxicillin first-line for prophylaxis; clindamycin for penicillin allergy.
- Ibuprofen vs. acetaminophen: ibuprofen anti-inflammatory, acetaminophen no anti-inflammatory effect.
- Epinephrine in local anesthetic: increases duration, but caution in cardiovascular disease.
Common Pitfalls
- Prescribing antibiotics for viral infections or non-infected swellings.
- Exceeding maximum dose of local anesthetic, especially in children.
- Not recognizing signs of anaphylaxis and delaying epinephrine administration.
Review Tasks

- Complications: dry socket, infection, nerve injury, sinus perforation.
Clinical and Exam Application
- For a horizontally impacted mandibular third molar, use a buccal flap and section tooth.
- For a patient with atrophic maxilla, consider sinus lift and bone graft before implant.
- For a fractured root tip, use a periotome and careful elevation to avoid sinus communication.
High-Yield Distinctions
- Coronectomy vs. extraction: coronectomy for high-risk IAN proximity; extraction for infected teeth.
- Primary vs. secondary closure: primary closure for clean wounds; secondary for infected sites.
- Resorbable vs. non-resorbable sutures: resorbable for deep, non-resorbable for surface.
Common Pitfalls
- Inadequate flap reflection leading to poor visibility and nerve damage.

- Duty to report (abuse, impairment, communicable diseases)
- Professional boundaries and conflict of interest
Key Notes
- Informed consent requires disclosure of risks, benefits, alternatives; patient must have capacity.
- Confidentiality is absolute except when required by law (e.g., child abuse, public health threats).
- Duty to report: report suspected abuse of children/vulnerable adults, impaired colleagues, and certain diseases.
- Avoid conflicts of interest: do not accept gifts that influence treatment decisions.
- Maintain professional boundaries: no romantic relationships with patients.
- Document all communications and consent discussions thoroughly.
Must Know
- Elements of informed consent: disclosure, comprehension, voluntariness, capacity.
- Provincial regulatory body standards (e.g., RCDSO, CDSBC) - verify with official sources.
- Mandatory reporting requirements for child abuse and neglect.
- Principles of patient safety: error reporting, root cause analysis, disclosure of adverse events.
Clinical and Exam Application
- Before extracting a tooth, explain risks (nerve injury, dry socket) and obtain written consent.
- If a patient discloses abuse, report to child protection services as required by law.
- If a colleague appears impaired, report to the regulatory body confidentially.
High-Yield Distinctions
- Express vs. implied consent: express for invasive procedures; implied for routine exams.
- Duty to report vs. duty to warn: report to authorities; warn potential victims (Tarasoff).
- Professional misconduct vs. malpractice: misconduct is ethical breach; malpractice is negligence.
Common Pitfalls
- Assuming consent is valid without checking capacity (e.g., dementia, intoxication).
- Sharing patient information with family without explicit permission.
- Failing to report a colleague's impairment due to loyalty.
Review Tasks

Evidence-Based Practice and Clinical Research Interpretation
Syllabus Focus
- Study design and levels of evidence
- Critical appraisal of literature
- Statistical concepts (p-value, confidence intervals, NNT)
- Applying evidence to clinical decisions
Key Notes
- Hierarchy of evidence: systematic reviews > RCTs > cohort studies > case-control > case series.
- Critical appraisal: assess validity, results, and applicability using tools like CASP.
- Understand p-value: <0.05 indicates statistical significance, but not clinical importance.
- Number needed to treat (NNT) = 1/absolute risk reduction; lower NNT is better.
- Confidence intervals: if includes 1.0 for odds ratio, result not significant.
- Apply evidence considering patient values and clinical expertise.
Must Know
- Types of bias: selection, performance, detection, attrition, reporting.
- Sensitivity vs. specificity: sensitivity = true positive rate; specificity = true negative rate.
- Positive predictive value (PPV) and negative predictive value (NPV) depend on prevalence.
- Intention-to-treat vs. per-protocol analysis: ITT preserves randomization.
Clinical and Exam Application
- When evaluating a new implant surface, look for RCTs comparing survival rates.
- Use NNT to explain benefit of a treatment to a patient (e.g., NNT=10 means 1 in 10 benefits).
- Critically appraise a study on periodontal therapy: check for blinding and follow-up.
High-Yield Distinctions
- RCT vs. observational study: RCT provides strongest evidence for causality.
- Systematic review vs. narrative review: systematic review is comprehensive and reproducible.
- Absolute risk reduction vs. relative risk reduction: ARR is more clinically meaningful.
Common Pitfalls
- Confusing statistical significance with clinical significance.
- Ignoring study limitations and conflicts of interest.
- Applying results from a different population to your patient without considering generalizability.
Review Tasks
- Practice critical appraisal of a journal article using CASP checklist.
- Calculate NNT from a given study.
- Review common statistical tests (t-test, chi-square, ANOVA).
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
- Review all six subjects, focusing on high-yield distinctions and common pitfalls.
- Practice with RCDC-style questions and OSCE scenarios from official resources.
- Ensure familiarity with current guidelines (e.g., antibiotic prophylaxis, periodontal classification).
- Verify any specific provincial regulations with your regulatory body.
- Simulate exam conditions: time yourself on practice tests and OSCE stations.
