Effect of using tri-calcium phosphate combined with platelet rich fibrin versus platelet rich plasma in post extraction socket

Abstract

Objectives: This study was designed to evaluate the effect of using tricalcium phosphate combined with platelet rich fibrin versus platelet rich plasma in post extraction socket clinically and radiographically at maxillary esthetic zone. Subject and methods: This study was conducted on 30 patient seeking extraction of at least one hopeless tooth, they distributed into 3 groups.10 patients for control group , 10 patients for test group (a) and 10 patients for test group (b). In control group the socket was left to heal spontaneously by clot formation. In test group (a) the socket was filled with beta-tricalcium phosphate as bone graft and platelet rich fibrin. In test group (b) the socket was filled with beta-tricalcium phosphate and platelet rich plasma. CBCT image was taken to compare the vertical, horizontal ridge dimension and bone density pre-operatively and 6 month post-operatively. Result: There was statistically non-significant difference regarding the vertical height, bone width, buccal plate thickness and bone density in both groups pre-operatively. But after 6 months post-operatively there was statistically significant difference regarding three groups in all parameters. The test group (a) that represented βTCP and PRF showed a lower percentage of a change than test group (b) that represented βTCP and PRR than control group. Conclusion: The use of PRF accelerates socket wound healing after tooth extraction as noticed by reducing vertical and horizontal bone loss and maintaining favorable bone density values after 6 months postoperatively.
