Inferior Alveolar Nerve Injury Caused by Coronectomy or Conventional Method in Third Molar Extractions.
J Rawal Med Coll Jan ;21(2):122-6.

Background: To compare the frequency of injury to the inferior alveolar nerve as a result of coronectomy and removal of mandibular third molars having nerve approximation. Methods: In this comparative study 110 patients with inferior alveolar nerve approximation were selected and randomly allocated into Group-A and Group-B. Group-A patients underwent coronectomy and Group-B patients underwent traditional removal. Inferior alveolar nerve damage was assessed one week post operatively, then further assessed after 01, 03 and 06 months. Results: Out of total 110 patients included in the study, 9 (8.2%) patients were having nerve damage. In traditional removal group, 9 (16.4%) patients were found to have nerve damage. Seven patients with nerve injury recovered within 06 months whereas 2 patients had permanent nerve damage. In coronectomy group none of the patients had nerve damage. Conclusion: Coronectomy is an effective procedure in significantly reducing the incidence of inferior alveolar nerve injury when compared with traditional removal of wisdom teeth.
