Abstract
Background: The most common surgical treatment in the oral cavity, third molar extraction, has been linked to more than50% of trigeminal nerve injury[1,2]. Complications
can arise during or after surgery; the complication rate for third molar extraction ranges
from 4.6% to 30.9%,The aim of our study is to evaluate intra and postoperative
complications of Coronectomy for lower wisdom tooth.
Patients and method: A total of 68 radiographs from 68 patients who had coronectomy were collected from the Smile Infinity Dental Center database in Erbil, Kurdistan Iraq. It was necessary to determine the precise anatomy and location of the tooth utilizing
orthopantomogram (OPG) and cone-beam computed tomography as a requirement for minimally invasive wisdom tooth surgery (CBCT).
Results:68 patients were enrolled in this study with a total of 136 lower third molars. Ages
between 25 and 35 years. Patients are predominantly females(41female -27 male)
134sites healed primarily, but in 1 case the sockets on both sides opened and failed to
close secondarily. In this case, the root fragments were later removed and found to be mobile.
Conclusions and Suggestions: Coronectomy has almost no effect on increasing intraoperative or postoperative problems. Infections and long-term reinterventions are
uncommon. Root migration away from the mandibular canal can occur in a variety of
directions. Finally, there are numerous alternatives to coronectomy, but they are limited in their indication because they require certain circumstances.
