Abstract
PRF is an autologous platelet concentrate suspended in a small plasma volume. The aim of the present study was to evaluate the use of platelet - rich fibrin (PRF) as a grafting material for socket preservation both clinically and radiographically. Ten patients; 7 females and 3 males, with a mean age of 32.4 years (with the range of 17 - 45 years) were included in this study with 2 contralateral symmetrical teeth in the same arch (split mouth design) indicated for extraction, divided into 10 extraction sockets that received PRF as a grafting material for socket preservation, and 10 extraction sockets that were not grafted to serve as a control, where the the bucco - lingual bone width has measured at the crestal bone level, 3mm and 6mm beneath the crestal bone level, the crestal bone height at the distal and mesial alveolar crest of the socket and bone density was measured using the image software of digora (soredex) system and also the width of the attached gingiva was measured, and all measurement was done for both sites immediately after extraction, and three months after extraction, then the patients were scheduled for implant placement
