Grade C molar‐incisor pattern periodontitis classification and its challenges

In the conclusion of this paper, we suggest expansion and clarification of the current classification system to: (1) recognize periodontitis in the primary dentition; (2) distinguish patients with grade C periodontitis by the presence or absence of modifying factors; and (3) introduce a subclassification for grade C cases predominantly affecting young patients. These refinements may improve diagnostic accuracy and support more targeted research, prevention, and treatment for at-risk youth.
