Abstract
Periodontitis, evoked by the dental plaque that forms around teeth, progressively destroys the periodontal tissue supporting the teeth, including the periodontal ligament, cementum, alveolar and gingival and ultimately leading to loss of the affectd teeth. (Nishihara & Koseki 2004). For decades, intrabony defects had been regarded as a challenging scenario for periodontal therapy and a serious threat for tooth prognosis and progression of periodontitis where teeth mortality had been reported to occur more frequently in intrabony defects than in similar teeth with suprabony defects (Papapanou & Wennstrom, 1991).The aim of this study was to evaluate clinically & radiographically the effects of recombinant bone morphogenic protein (rhBMP-2) on periodontal regeneration of intrabony periodontal defects in human and histologically on the experimentally created intrabony defects in dogs.
