Evaluation of Outcome Following Coronectomy for the Management of Mandibular Third Molars in Close Proximity to Inferior Alveolar Nerve.

Introduction: Iatrogenic damage to Inferior Alveolar Nerve (IAN) is a significant risk factor following prophylactic or therapeutic removal of impacted mandibular third molar. The risk to IAN injury increases many fold, when the third molar root overlaps the nerve canal as identified by the radiographic imaging. Various methods like orthodontic assisted extraction, staged removal of tooth or coronectomy have been advocated to reduce the incidence of IAN injury in high risk cases with variable outcome.
