Mandibular body fractures frequently result in inferior alveolar nerve (IAN) and mental nerve injuries which ultimately leads to paresthesia of chin and lower lip area. The objective of this study is to evaluate the efficacy of platelet rich fibrin (PRF) application to mental nerve during open reduction and internal fixation (ORIF) of patients having neurosensory disturbance (NSD) following mandibular body fracture involving mental foramen. The PRF application to mental nerve in mandibular body fractures will not only aid in hard and soft tissue healing but also prove to be a game changer for a holistic healing of a patient rather than separate surgical procedures for nerve repair such as microsurgery, grafting, tissue glues, laser.
Alternate Hypothesis HA= The application of PRF to the mental nerve during open reduction and internal fixation of mandibular body fractures involving the mental foramen significantly improves neurosensory recovery compared to cases where PRF is not applied.
Null Hypothesis HO= The application of PRF to the mental nerve during open reduction and internal fixation of mandibular body fractures involving the mental foramen does not significantly improve neurosensory recovery compared to cases where PRF is not applied.
Patients having neurosensory disturbance following mandibular body fracture involving mental foramen and pre-operative TPD discrimination score '0' or '1' will be selected in this study ( as per operational definition). TPD discrimination will be recorded; Preoperatively Immediately post operatively After 6 months
