Abstract

Objective: The aim of the present study is to evaluate the use of autogenous particulated dentin mixed with platelet rich fibrin in surgically removed lower third molar socket
.
Subjects and Methods: Sixteen patients (7 male and 9 female) were presented. Their age ranged from 20 to 37 years. Patients were randomly divided into . Group I, PD/PRF mix was grafted into the extraction socket.and group II, extraction socket was left without grafting. The CD, CAL and WAG of lower second molar were measured at 2, 4, 8 and 12weekes after surgery. MBL distally to lower second molar was evaluated at 1 and 6months after surgery. BD was measured 6 months after surgery.

Results: The PD/PRF mix group showed significant reduction of CD than the no grafted group. The PD/PRF mix group showed significant reduction of CAL than the no grafted group. The PD/PRF mix group showed significant less reduction of WAG than the no grafted group. The PD/PRF mix group showed significant less amount of MBL loss than the no grafted group. There was a significant increase of BD distally to lower second molar at 6 month in PD/PRF mix group than the no grafted group.

Conclusion: Autogenous particulate dentin and platelet rich fibrin mix provided promising clinical outcomes and considered an ideal bio-active graft material for hard tissue regeneration. Also,this mix may assist healing and counteract pronounced alveoalr resorption distally to lower second molar.
