This study is a randomized, parallel active controlled trial evaluating the healing of extraction socket with eggshell derived nanohydroxyapatite graft covered with platelet rich fibrin and eggshell derived nanohydroxyapatite graft alone and this study will be conducted in the department of Clinical Research. The study subjects will be enrolled from the out-patient department of Oral and Maxillofacial Surgery. They will be randomly allocated into two groups and the consent will be obtained from the participants. The study participants will undergo atraumatic extraction. After achievement of post extraction hemostasis, nano-hydroxyapatite graft will be placed into the extraction socket till the crestal level and PRF membrane will be placed over the grafted socket and tucked between Buccal and Lingual/Palatal gingiva and stabilized using 3-0 black silk suture (figure of eight) in one group. In another group, nano-hydroxyapatite graft alone will be placed into extraction sockets up to the crestal level and will be sutured using 3-0 black silk suture (figure of eight). After the procedure, the subjects will be advised to follow post extraction instructions. All the subjects will be followed up for 90 days for any adverse events and the parameters like soft tissue healing, pain and alveolar width and height will be assessed on 7^th, 14^th and 90^th day post operatively. 

Preparation of Platelet Rich Fibrin (PRF) membrane: This will be prepared using autologous blood under standard aseptic precautions. Intravenous blood of 5 ml will be drawn from the precubital region using a sterile disposable syringe. Blood will be centrifuged using a tabletop centrifuge for 10 minutes at 3000 rpm immediately. The resultant product will consist of acellular plasma at the top, PRF clot in the middle, and red blood cells at the bottom. PRF component will be separated and molded into a thin sheet of approximately 1x1 using a sterile wet gauze piece.
