TOPIC: CLASSIFICATION OF PERIODONTAL DISEASES

📌 POINTS TO PONDER 

➡️ Main features of AAP 1999 classification system are as follows:

🔹Addition of gingival disease component: Comprehensive section of gingival diseases is included in this classification.

🔹Replacement of adult periodontitis with chronic periodontitis: There is replacement of the term “adult periodontitis” with chronic periodontitis, since epidemiological evidence suggests that chronic periodontitis may also be seen in adolescents.
