Based on the findings, what Stage and Grade would be assigned under the 2018 AAP Classification?

• A. Stage II, Grade A
• B. Stage III, Grade B
• C. Stage III, Grade C
• D. Stage IV, Grade C

Answer: (C)

In the 2018 AAP system, you separate how severe the disease is (Stage) from how fast it’s progressing (Grade). Stage III is chosen when there is severe loss of supporting bone with substantial attachment loss, deep pockets, and often tooth mobility or loss, indicating a need for more complex or surgical treatment. Grade C is used when progression is rapid—bone loss or CAL increases quickly over time, and risk factors like smoking or systemic diseases can accelerate it. The findings described align with Stage III because the disease shows extensive bone loss extending into the middle third of the roots and meaningful attachment loss with deep pockets, signaling severe periodontitis and greater treatment complexity. It aligns with Grade C because the deterioration is rapid, not gradual, indicating a fast progression rate. Therefore, the combination Stage III, Grade C best fits.
