• Research summary

  Coronectomy is an alternative procedure for extraction of high risk wisdom teeth that are intimately related to the inferior alveolar nerve. The inferior alveolar nerve supplies sensation to the lower lip and chin and damage to this nerve could result in tingling, numbness, burning or even a pain sensation of the lower lip or chin which can be temporary or permanent. The procedure aims to remove only the crown of an impacted lower wisdom tooth and leaving the roots undisturbed in place, in order to avoid injury of the nerve.

  Postoperative coronectomy complications have been reported through the years and further research can help minimise or even eliminate this risk to the nerve. Extensive research will also help us improve our knowledge on the subject and provide better health care and treatment to patients.

  The present study is a 10-year retrospective observational study. It intends to search through the database (Computer record system) of patients that had coronectomy in the Edinburgh Dental Institute (EDI) and Chalmers Dental Centre.
  Patients will be recalled and assessed in one appointment lasting approximately 45 minutes. During this appointment interview and clinical oral examination will take place and the patient will be assessed for occurrence of postoperative complications. These would be 1) IAN (Inferior Alveolar Nerve) injury 2) pain 3) infection 4) dry socket (condition that occurs after the extraction of teeth, resulting to increasing pain). We will also examine the occurrence of root migration (roots that are left in place undisturbed, may after some time start to move towards the surface in the mouth) and the need for reoperation. In some cases a postoperative radiograph may be indicated, to assess for any related pathology.
