Retrospective evaluation of inferior alveolar nerve neuropathies after impacted third molar surgery with mandibular canal close position

The main causes of nerve trauma during surgery to remove an impacted tooth were identified. The longest periods of neuropathy of the inferior alveolar nerve were found in patients with nerve damage by a drill during root separation, with an interroot type of position of the mandibular canal; and with nerve damage by a sharp edge of a tooth with a combination of lingual location of the mandibular canal and a pronounced root anomaly in the form of hypercementosis and dilaceration.
