Periodontal classification, staging and grading, non-surgical therapy, surgical principles, and supportive maintenance — structured for OSCE, viva, and board exams.
What examiners focus on
- 2018 classification of periodontal diseases — stages I–IV, grades A–C
- Periodontal assessment — BPE/PSR, probing depths, CAL, radiographic bone loss
- Non-surgical therapy — scaling, root surface debridement, adjunctive antibiotics
- Risk factor identification — smoking, diabetes, genetic susceptibility
- Surgical indications — when non-surgical therapy is not enough
- Supportive periodontal therapy — recall intervals and re-evaluation criteria
- Perio-endo lesions and furcation involvement classification
5 tips for periodontology exams
- Staging and grading is the most tested topic — know the criteria for each stage and grade cold, including the complexity factors.
- Examiners want you to stage AND grade every case — don't just say "Stage III," always add the grade with your reasoning.
- Non-surgical therapy vivas expect a phased approach — cause-related therapy first, then re-evaluation, then surgery if needed.
- Risk factor questions are easy marks — always mention smoking (pack-years), diabetes (HbA1c), and compliance.
- Maintenance questions test your recall interval logic — explain why 3 months vs 6 months based on risk profile.
