Classification of Periodontitis

Abstract

The concept of classification is often perceived as tedious; however, it remains a critical component in organizing similar disease phenotypes into unified syndromes. Over the years, numerous efforts have been made to refine the classification of periodontal diseases. The evolution of these systems reflects three prominent paradigms that shaped the understanding of periodontal pathologies. Among the various systems developed, the 1999 American Academy of Periodontology (AAP) classification stands out as the most comprehensive and widely accepted. This system was introduced to address the limitations, inconsistencies, and deficiencies identified in the 1989 classification. Additionally, the AAP provided a detailed analysis and justification for the modifications and changes, cementing its relevance in clinical and research settings
