Evaluation of Dentin Graft and I-PRF With and Without Vitamin C for Post-extraction Socket Preservation

Flapless atraumatic extraction. After thorough mechanical cleaning, the sockets will be rinsed with 5 ml of an aqueous 0.125% chlorhexidine digluconate solution, followed by a 5 ml sterile saline rinse to remove tissue debris from the socket. Followed by inspection of extraction socket integrity, using a William's graduated periodontal probe. Extracted teeth will be cleaned from periodontal ligaments, cementum, soft tissue attachment, caries or restorations using a high-speed fine finishing stone and saline irrigation. The pulp chamber will be cleaned with sterile endodontic files. Teeth will be ground, using hand bone mill.The (ADDG) particles prepared by demineralization of tooth particles in 0.6N hydrochloric acid for 30 min to achieve demineralized then washed twice in saline and dried with sterile gauze. For i-PRF blood will be withdrawn in plastic tubes. The tube will be centrifuged at around 700 RPM for 3 minutes, and extraction socket will be filled with the graft material.

Extraction socket will be filled with the corresponding graft material and the dentin graft.
