Evaluation of the effects of platelet-rich fibrin and piezosurgery on outcomes after removal of ımpacted mandibular third molars

Abstract

We compared postoperative outcomes after the removal of 80 impacted mandibular third molars in 59 patients. In the control group, osteotomies were done with traditional burs (n=20). The second group had traditional osteotomies and platelet-rich fibrin (PRF) placed into the socket of the extracted tooth (n=20). The third group had piezosurgery (n=20), and the fourth had piezosurgery and PRF placed in the extraction socket (n=20). Baseline variables were assessed preoperatively and included pain, the number of analgesics taken, trismus, and swelling. These were also assessed on postoperative days 1, 2, 3, and 7. There was a significant reduction (p<0.05) in pain on days 1, 2, and 3, and in the number of analgesics taken on days 2 and 3 in both PRF groups. However, in the piezosurgery alone group this was the case only on day 3. There was no significant difference in swelling and trismus between the control and other groups.
