Periodontitis

Periodontitis has been defined as an infectious disease causing inflammation within the supporting tissues of the teeth, which results in progressive attachment and bone loss.

Periodontitis is characterized by pocket formation, with or without gingival recession. It results in loss of periodontal ligament, alveolar bone, and connective tissue.

Periodontal pockets are pathological fissures between a tooth and crevicular epithelium with their apex at the junctional epithelium. They are caused by apical migration of the junctional epithelium along the root as the periodontal ligament is detached.
