Abstract

Purpose : Latrogenic inferior alveolar nerve injury is highly probable during third molar surgeries especially in cases where the roots are in close approximation with the inferior alveolar canal. It presents as a difficult clinical situation with the patient having altered sensations for a varied period of time. The aim of the study was to evaluate the efficiency of partial odontectomy in preventing injury to inferior alveolar nerve without causing any other complications

Patients and methods : A study design with a sample size of twenty patients, all of whom had impacted mandibular third molars in close approximation with IAN evaluated by IOPAR's and panaromic radiographs was considered. Ten patients were included in group I who underwent partial odontectomy and ten patients in group II underwent complete surgical removal of impacted mandibular molars.

Results : The mean follow up time for both the groups was six months. One case of Inferior alveolar nerve injury was found in the surgical removal group ,who developed signs of neuropraxia which resolved within a week. One case in complete surgical removal group developed a dry socket while none of the cases in coronectemy group developed a dry socket. Post operative infection was seen in none of the cases in both the groups

CONCLUSION : Partial odontectomy/coronectomy is an alternative technique to preserve the vitality of inferior alveolar nerve in selected cases. A long term followup period is required to assess the fate of the embedded root after coronectomy.

Key Words : Odontectomy, Mandibular Third Molar, Impacted Tooth
