Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The use of PRF may provide a beneficial effect in virtue because it contains several growth factors and may enhance epineurium fibroblast regeneration. PRF has better efficacy than PRP and normal saline (control) in functional nerve recovery (Khojasteh et al.,2016). The use of PRF placement 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 (Preponement et al.,2013) rather than separate surgical procedures for nerve repair such as microsurgery, grafting, tissue glues, laser.
Limited studies have been done regarding the role of PRF in neurosensory disturbance following mandibular body fractures. The most recent study conducted by Tabrizi et al.(2024) who studied the role of PRF in neurosensory recovery following mandibular body fractures. In this study PRF was placed on IAN between fracture segments. This study had several limitations such as low sample size and there was no direct application of PRF to mental nerve, which may be a factor in NSD. The actual sample size was lower i.e 25 patients as compared to their calculated sample size i.e 30, because 5 patients did not return for follow-up. Our study will provide more significant data related to efficacy of PRF application to mental nerve in patients having neurosensory disturbance 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.

Case Group
The group in which PRF will be placed over mental nerve during open reduction and internal fixation of patients with mandibular body fractures involving mental foramen.
Platelets rich Fibrin
PRF is the second generation autologous platelet concentrate that is obtained from patient's own blood in simple and cost effective manner. PRF is comprised of three main specifications. First, the existence of platelets and their active growth factors i.e. platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor (TGF), insulin-like growth factor (IGF) and epidermal growth factor (EGF). Second, the role of leukocytes and cytokines i.e. TNF alpha, IL-6 and IL-1ɓ in anti-inflammatory response and immune modulation. Third, the fibrin meshwork where these platelets, cytokines and growth factors are embedded and subsequently released after a short period
