Evaluation of effects of platelet-rich fibrin on treatment outcomes after impacted mandibular third molar surgery: A randomized controlled clinical study.

Background and Objective: Impaction of the third molar teeth is a common disorder which often necessitates their removal. After third molar surgery, the common postoperative sequelae are pain, trismus, and buccal swelling. Our study sought to evaluate the effect of platelet-rich fibrin (PRF) on postoperative pain, swelling, trismus after surgical extraction of impacted mandibular 3rd molars. Materials and Methods: Over a period of 22 months (December 1, 2016-September 30, 2018), 44 patients in the age group of 18-40 years, who required surgical extraction of impacted third molar and met the inclusion criteria were recruited. After surgical extraction of the third molar, only primary closure was performed in the control group (22 Group), whereas PRF was placed in the socket followed by primary closure in the study group (22 patients). The outcome variables were pain, swelling, and maximum mouth opening were measured with a follow-up period of 1 week. Results: The application of PRF in the study group lessens the severity of immediate postoperative sequelae such as pain, swelling, and trismus compared to the control group. Conclusion: The treatment outcomes and postoperative sequel were better in the PRF group as compared to other control group on days 1, 3, and 7 postoperatively.

Removal of Displaced Maxillary Third Molar Using Modified Gillie's Temporal Approach.

Tooth impaction is a pathological situation where a tooth is unable to achieve its normal functional position within the expected time span. The removal may be associated with intra-operative or post-operative complications. The Le Fort I osteotomy is a procedure used by maxillofacial surgeons to correct a wide range of dentofacial deformities. Due to its versatility and simplicity, it has gained popularity for a wide range of uses. This case report describes the location and surgical removal of a right maxillary third molar which was accidentally displaced into the infratemporal fossa in a 26-year-old female while performing Le Fort I osteotomy. The patient underwent a second surgery for the retrieval of tooth using modified Gillie's temporal approach. The important role of the cone beam computed tomography in determining the localization of the displaced tooth is demonstrated.
