Analysis of clinical and radiographic outcomes at least 5 years after coronectomy for deeply impacted mandibular third molars.

Objective: Coronectomy is an alternative to traditional mandibular third molar extraction when the inferior alveolar nerve (IAN) is closely associated with the roots of these molars. Given the paucity of research on the long-term outcomes after coronectomy, we conducted this study to evaluate clinical and radiographic outcomes at least 5 years post-coronectomy.

Methods: This retrospective study enrolled all patients with impacted mandibular third molars treated with coronectomy at our institution who were willing to return for follow-up evaluation 5 years or more after their original procedure.
