Which of the following is NOT a recognized form of necrotizing periodontal disease in the 2017 classification?
Answer: Necrotizing mucositis
The 2017 classification recognizes necrotizing gingivitis, necrotizing periodontitis, and necrotizing stomatitis; necrotizing mucositis is not a distinct recognized entity.
What is the significance of 'complexity factors' in the 2017 periodontitis staging system?
Answer: They determine the minimum stage a patient can receive
Complexity factors such as furcation involvement, bone defect patterns, and tooth mobility establish the minimum stage a case can be classified at.
Which condition is classified as 'periodontitis' under the 2017 classification but was previously considered a separate disease?
Answer: Both A and C
Both 'chronic periodontitis' and 'aggressive periodontitis' were eliminated as separate categories and integrated into the Stage/Grade periodontitis framework.
Gingival enlargement caused by phenytoin (Dilantin) is classified under which category?
Answer: Drug-influenced gingival condition
Drug-influenced gingival conditions, including those caused by phenytoin, cyclosporine, and calcium channel blockers, are classified as a distinct category in the 2017 framework.
Which of the following best describes 'molar-incisor pattern' in the context of the 2017 classification?
Answer: A distribution descriptor that may suggest Grade C or systemic disease
Molar-incisor pattern is an incidental finding that may suggest Grade C periodontitis or a systemic condition as a primary driver, prompting further investigation.
A 40-year-old non-smoker with no systemic disease has 30% bone loss evidenced radiographically over the past 4 years. What grade would best apply?
Answer: Grade C
A bone loss rate suggesting >0.25mm/year with no risk factors still qualifies as Grade C based on primary evidence of rapid progression.
Under the 2017 classification, which of the following is the primary determinant of the 'stage' of periodontitis?
Answer: Severity of attachment and bone loss plus complexity
Stage is primarily determined by the severity of attachment and bone loss, along with complexity factors that affect disease management.
