Comparative evaluation of the effectiveness of bioresorbable collagen membrane in combination with deproteinized bovine bone matrix xenograft (DBBM), and advanced platelet rich fibrin membrane in combination with deproteinized bovine bone matrix xenograft for periodontal regeneration

Introduction: Periodontitis is a chronic, multifactorial, inflammatory disease that leads to gradual loss of bone and periodontal attachment. Thus, periodontal surgery is required according to severity of diseases. The goal of periodontal reconstructive surgery is to regenerate soft and hard tissues destroyed during periodontal disease. Aim: To compare the effectiveness of bioresorbable collagen membrane in combination with Deproteinized Bovine Bone Matrix xenograft (group A); and Advanced Plasma rich fibrin(A-PRF) membrane in combination with Deproteinized Bovine Bone Matrix xenograft (group B) in the treatment of human infrabony defects. Methods: : This randomised controlled trial will be carried out at the periodontics outpatient department. We will choose 24 patients with moderate to advanced chronic periodontitis who are otherwise systemically healthy. Infrabony defects will be treated by open flap debridement using bovine-derived xenograft and bioresorbable collagen membrane (group A) and open flap debridement using bovine-derived xenograft and A-PRF after the completion of first therapy (group B). At baseline and six months after undergoing periodontal surgery, probing pocket depth, clinical attachment level, radiographic bone fill, gingival recession, oral hygiene status, and gingival health will be measured. Expected results: It is suggested that Bioresorbable Collagen Membrane in combination with Deproteinized Bovine Bone Matrix xenograft will show better results as compared to Advanced Platelet Rich Fibrin Membrane with Deproteinized Bovine Bone Matrix Xenograft.
