Aim: To evaluate the role of platelet-rich plasma on the healing of extraction socket. Methods: 40 patients with an unremarkable medical history, subjects with at least one site bordered by minimum of one tooth, nonsmokers, teeth with root fracture, patients having teeth with hopeless periodontal prognosis, teeth with failed endodontic therapy or advanced carious lesion. The patients fulfilling the criteria were randomly allocated into two groups: Group I (test group-n = 20): Extraction sockets which received platelet rich fibrin. Group II (control group-n = 20): 10 extraction sockets left for normal healing (blood clot). Result: 40 patients aged between 22 and 52 (mean 36.8) years, including 25 females and 15 males completed the study. Each patient had single tooth extraction. The width of the alveolar ridge was measured after extraction (at baseline) as well as 1 week, 4 weeks, and 8 weeks in both the control and the test groups. The test group presented with a mean horizontal ridge width of 12.94 ± 3.33 mm after extraction, which reduced to 12.70 ± 3.37, 12.33 ± 3.30 and 11.97 ± 3.33 mm at 1, 4 and 8 weeks respectively. For the control group the mean horizontal ridge width was 14.46 ± 4.13 mm after extraction, which reduced to 14.01 ± 4.00 mm, 13.04 ± 3.50 mm and 12.54 ± 3.42 mm at 1, 4 and 8 weeks respectively. The mean radiographic bone fill (RBF) percentage in the con- trol group at 1, 4 and 8 weeks was 69.82 ± 2.07%, 75.03 ± 2.22% and 81.35 ± 3.61% respectively. While in the test group, the mean radiographic bone fill percentage was 75.05 ± 2.66%, 82.54 ± 4.33% and 89.81 ± 2.53% at 1, 4 and 8 weeks respectively. Conclusion: We concluded that the use of PRP accelerates socket wound healing after tooth extraction as noticed by increased bone fill and reduced alveolar bone width resorption using clinical and radiographic methods.
