[Progression and stagnation of periodontal disease].

Abstract

Local factors may contribute to acute exacerbations of the periodontal disease, however, their pathological basis is systemically established. The more bacteria and bacterial products get into the periodontal tissue the more serious is destruction. Host's resistance controls composition of the subepithelial bacterial flora. Under condition of defective phagocyte function bacteria, otherwise occurring rarely in the pocket, multiply quickly and penetrate the periodontal pocket epithelium. Specific immune defence can stop them only in the subepithelial conjunctive tissue causing its destruction. Juvenile periodontitis goes with defects of granulocyte function and an aggressive pocket flora. These patients need antibiotics taken systematically, removing of the infected pocket epithelium and regular recalls. Care of patients with adult periodontitis is limited to good oral hygiene.
