Which statement about the 7 1/2-year-old patient case is true?

• A. The patient has generalized periodontitis.
• B. The patient has localized periodontitis with molar/incisor pattern, Stage III, Grade B.
• C. The patient is not indicated for periodontal evaluation.
• D. The patient is an adult.

Answer: (B)

The main idea is recognizing a localized aggressive pattern of periodontal disease in a child and applying the staging and grading to describe its severity and rate of progression. In kids, a localized aggressive form commonly shows attachment loss and bone loss around the first molars and the incisors—the molar/incisor pattern—while the rest of the dentition remains relatively unaffected.

So, describing the case as localized periodontitis with a molar/incisor pattern fits what we’d expect for this type of disease. Stage III reflects advanced bone loss around the involved teeth, with significant attachment loss and involvement that raises concerns about future tooth stability, while Grade B indicates a moderate rate of progression, which aligns with the typical progression seen in localized aggressive periodontitis in young patients.

The other statements don’t fit this scenario: generalized periodontitis would involve multiple teeth beyond the molars and incisors; not indicating periodontal evaluation would ignore the clear signs; and labeling the patient as an adult contradicts the age given.
