Abstract: Surgery to remove impacted lower third molars involves risk for exposing the inferior alveolar neurovascular (IAN) bundle. The platelet rich fibrin (PRF) should be adequate to facilitate healing in self-contained defects and has been widely used in the oral and maxillofacial surgery. Therefore, we used PRF to treat patients whose IAN bundle was exposed during surgery. With a 98% chance of recovery at one-year post-surgery after treatment with PRF, seeing an exposed IAN bundle during impacted lower third molar removal surgery also suggests its close association with the third molar and poses a 20% risk of paresthesia. The use of PRF is such patients could support healing that can lead to promising result.
