AGGRESSIVE PERIODONTITIS: INTRODUCTION, CLASSIFICATION AND PATHOGENESIS
AUTHOR: Sanketh DS, MDS
Periodontitis refers to the inflammation of the supporting periodontal tissues surrounding the tooth. It is caused by specific groups of micro-organisms and results in progressive destruction of the periodontal fibres and the alveolar bone. Chronic periodontitis is the most common form of periodontitis, has a slow rate of progression and most commonly affects adults and sometimes even children and adolescents. It is associated with accumulation of plaque and calculus but the rate of disease progression also depends on local (morphology of teeth, restorations), systemic (diabetes mellitus, HIV/AIDS) and environmental factors (cigarette smoking). Aggressive periodontitis (AP) on the other hand, differs from the chronic form by 1) occurring primarily in adolescents and young adults, 2) causing rapid destruction of the periodontium with very little or no plaque and calculus accumulation, 3)occurring in healthy individuals with no systemic disease and 4) having a genetic predisposition.
