Hydroxyapatite in periodontal bonedefects

Abstract

Periodontitis is a destructive disease of the deep periodontal tissues, characterized by progressive bone loss; it is the second cause of tooth loss. A therapeutic option is the grafting of hydroxyapatite, which is highly biocompatible and osteo-conductor. This is a presentation of two cases of patients referred from primary health care suffering from tooth mobility grades II and III, periodontal recession significantly affecting the bone, with real periodontal pockets, such as: dental plaque, food retention, bleeding and gingival inflammation, halitosis and morphology loss. With previous prescription of medicine therapy and hematological study, a periodontal flap was performed for placing the granulated bio-material, hydroxyapatite, in the bone defects. Reduction of the tooth mobility, amelioration of the gingival retraction level, diminishment of pockets depth and remission of symptoms were accomplished. There were no adverse reactions to the treatment. In the periapical radiographic exam, a bone neo-formation grade was detected, and the patients were followed up for three months.
