When evaluating a patient for periodontal surgery, which radiographic feature most strongly contraindicates an osseous resective procedure?
Answer: Vertical bone defects exceeding 3 mm
Vertical (angular) bone defects are better managed with regenerative approaches rather than osseous resection, which would sacrifice additional bone.
A patient presents with a probing depth of 5 mm and bleeding on probing at site #14 mesial. Radiographically, there is 2 mm of horizontal bone loss. What is the most accurate classification for this defect?
Answer: Stage II Grade B
Stage II is indicated by probing depths 4–5 mm with 15–33% bone loss, and Grade B reflects moderate rate of progression without systemic modifiers.
Which clinical parameter is most predictive of tooth loss over time during periodontal maintenance evaluation?
Answer: Residual probing depth ≥6 mm after active therapy
Residual probing depths ≥6 mm after active periodontal therapy are the strongest clinical predictor of future attachment loss and tooth loss.
During a re-evaluation 8 weeks after scaling and root planing, which finding would most indicate the need for surgical intervention?
Answer: Persistent probing depths of 6 mm with no attachment gain
Persistent deep pockets without clinical attachment gain after thorough non-surgical therapy indicate that surgical access is necessary.
Which parameter is used in the 2017 AAP/EFP classification to distinguish generalized from localized periodontitis?
Answer: Number of teeth involved (more than 2 non-adjacent teeth)
Generalized periodontitis is defined as involvement of more than 2 non-adjacent teeth; localized involves ≤2 non-adjacent teeth or a molar-incisor pattern.
When evaluating furcation involvement of a maxillary first molar, which probe is specifically recommended for assessing the palatal furcation?
Answer: Nabers 1N probe from the mesio-palatal approach
The Nabers 1N curved probe inserted from the mesio-palatal line angle is the standard approach for accessing the palatal furcation of maxillary molars.
A patient with poorly controlled type 2 diabetes (HbA1c = 9.5%) presents with Stage III periodontitis. According to ABP guidelines, how does this affect Grade assignment?
Answer: It modifies Grade B to Grade C due to a primary risk factor
Poorly controlled diabetes (HbA1c ≥7%) is a Grade modifier that can upgrade a case from Grade B to Grade C due to increased risk of rapid progression.
