A patient has diabetes that is well-controlled. How does this affect the grading of their periodontitis?
Answer: May modify Grade B to Grade C if HbA1c ≥7%
Well-controlled diabetes (HbA1c <7%) may still upgrade Grade B to Grade C as a grade-modifying risk factor.
Which of the following is classified as a 'non-plaque-induced gingival condition' under the 2017 classification?
Answer: Desquamative gingivitis caused by mucous membrane pemphigoid
Desquamative gingivitis from mucous membrane pemphigoid is a non-plaque-induced condition as it results from an immune-mediated disorder.
Which staging criterion differentiates Stage II from Stage III periodontitis?
Answer: Bone loss confined to coronal vs extending to middle or apical third
Stage III is distinguished from Stage II by bone loss extending to the middle or apical third of the root, among other complexity factors.
Which term in the 2017 classification replaced the older term 'aggressive periodontitis'?
