Three-Dimensional Evaluation of the Effect of Platelet-Rich Fibrin on Edema in Lower Impacted Third Molar Surgery Performed with Piezosurgery

Platelet-rich fibrin (PRF) are widely used in impacted lower third molar (IL3M) 7 surgery and its effect on postoperative edema was generally analysed with linear methods.To analyze the effectiveness of platelet-rich fibrin (PRF) applied to the socket after tooth extraction in impacted lower third molar (IL3M) surgery performed with piezosurgery in the reduction of edema observed in the postoperative period, together with conventional (linear) and three-dimensional (volumetric) measurement methods.The study was designed as a prospective randomized split-mouth study and was conducted on 30 patients with bilateral IL3M teeth. Extraction of the patients' IL3M teeth was performed in the same session with the help of piezosurgery. After the extraction, PRF was randomly applied to one socket, but it was not applied to the other socket, which formed the control group. On the first, second, and seventh days after the procedure, volume was measured using 3dMD, and the distance between the topographic guide points was measured using a flexible ruler. The results were analyzed statistically. Alveolar osteitis (AO) presence was also recorded.A significant improvement in edema was observed in both groups, but no significant difference was found between the groups (P > 0.05). A moderate correlation was found between the two methods of measuring edema. AO was not seen in any patient.Although PRF reduces edema after IL3M tooth extraction and 3dMD is effective in its evaluation, it has no statistical advantage over classical methods.
