Aim of the study is to compare the treatment outcomes for intrabony vertical defects using autogenous bone graft alone and combination of demineralized bone matrix and autogenous bone graft. All participants will be explained about the need and design of the study. Informed consent will be obtained from the patients. Through clinical case history will be recorded. Each patient will undergo ultrasonic scaling (EMS) by a single operator. All clinical parameters (GI, PI, PPD, CAL, BOP) will be recorded using UNC15 periodontal probe (Hu Friedy )  at baseline, 3 months and 6 months interval. It is a single blind study in which the patient will be randomly assigned to either autogenous bone graft group (control) or combination of demineralized bone matrix and autogenous bone graft group (test) using manual lottery method. After allotment of the groups following surgical method will be performed. . Intraoral antisepsis will be performed with 10ml of 0.2% chlorhexidine digluconate rinse and by a povidine iodine solution extra oral antisepsis will be carried out. The site scheduled for surgery will be anesthetized by appropriate local anesthesia.  After administration of local anesthesia, incisions  will be made intracrevicularly  through the bottom of the pocket on both facial and the lingual/palatal as well as interdental  area. Incision will be performed from distal to mesial aspect of the area planned for the surgery. Mucoperiosteal flaps will be elevated beyond the mucogingival junction in order to achieve primary closure in all cases irrespective of groups. The marginal bone and diseased root surfaces will be exposed. Care will be taken to preserve as much interproximal soft tissue as possible. Meticulous defect debridement and root planning will be carried out using hand instruments and area-specific curettes in order to remove calculus, necrotic cementum and granulation tissues. No osseous recontouring will be performed, similar procedure will be performed for both control site and the test site. Control site will be treated with autogenous bone graft alone and test site will be treated with autogenous bone graft and demineralized bone matrix. The piezo electric device will be used for bone removal for autogenous bone grafting. It will placed directly into the recipient site. Autogenous bone graft of the required size will be procured by extending the mucoperiosteal flap in the adjacent tooth area to cover the osseous defect in the control group.  Combination of ABG + DMM will be used to cover the osseous defect in the test group. Mucoperiosteal flaps will be repositioned and secured in place using non-absorbable black silk suture. The interrupted sutures will be placed. The surgical area will be protected and covered with periodontal dressing. The following post operative care will be given to the patients Sutures will be removed after 7-10 days postoperatively.  Antibiotics & Analgesics will be prescribed. Each patient will be instructed for proper oral hygiene measure at each appointment. Patients will be instructed to avoid using toothbrush at the surgical site. Teeth cleaning will be initiated with gentle brushing using soft brush after suture removal. All clinical parameters will be re-evaluated 3 months and 6 months after surgery by second blinded operator. Radiographic parameters will be re-evaluated 6 months after surgery.
