CLINICAL EVALUATION OF BOVINE-DERIVED HYDROXYL APATITE IN THE TREATMENT OF PEIODONTAL OSSEOUS DEFECTS

Abstract

Infrabony defects represent one of the most demand­ mg therapeutic challenge in periodontics, although, conven­ tional periodontal therapy improves the prognosis of intra-os­ seous defects, regeneration of the destroyed periodontium has been the ultimate goal of periodontal therapy.

Bone replacement grafts have been used successfully to facilitate and promote periodontal regeneration.

The present study, was carried out to evaluate the use of anorganic bovine bone in the treatment of intrabony de­ fects in cases of marginal periodontitis.

The study was conducted on fifteen patients with thirty intrabony defects pocket depth more than 5 mm and probing attachment loss from 5 to 8.5 mm.

Clinical parameters were recorded after initial phase of scaling and root planing with antibiotics administration. The baseline clinical measurements included plaque index, gingival index, periodontal pocket depth, attachment level , gingival recession, and radiographic observations.
