Therefore, each these nerves is always at risk injury during extraction. Objectives: This study was evaluate anatomical factors nerve after surgical extraction molars patients visiting department oral maxillofacial surgery People’s Dental College Hospital. Methods: prospective conducted with 315 participants who presented a impaction underwent Intraoral Periapical Radiograph (IOPAr), panoramic radiograph, as well Cone Beam, Computed Tomography (CBCT). CBCT done those which close contact canal. Results: Collected data from showed that incidence alveolar (IAN) lingual nerve(LN)injury 0.31%. Of one had mesioangular class B, level II type 17year male other horizontal C, 47year female respectively. In both cases, tooth lingually placed relation IAN. Conclusions: Various responsible for molar. our study, IAN LN comparatively low most common factor angulation position
