Periodontal disease is a chronic inflammatory condition characterized by destruction of the periodontal tissues and resulting in loss of connective tissue attachment, loss of alveolar bone, and the formation of pathological pockets around the diseased teeth. Some level of periodontal disease has been found in most populations studied and is responsible for a substantial portion of the tooth loss in adulthood.
