Summary

Objective The present study aimed to evaluate which factors were statistically associated with a greater probability of inferior alveolar nerve (IAN) damage during lower third molar surgery.

Study Design A prospective observational study was performed at the Oral Surgery Unit of the Umberto I Hospital on 92 patients which underwent surgical extraction of a lower third molar, that was radiographically overlapped to the mandibular canal. All surgeries were performed by the same expert surgeon. A principal component analysis and the exact two-tailed Fisher test were used.

Conditions

  • Mandibular Nerve Injury

Interventions

PROCEDURE

lower third molar extraction

All surgeries were performed by the same expert surgeon (RP), with the buccal approach using local anesthesia, and included the following maneuvers: * luxation of the coronal portion of the tooth/root in an ipsilateral or parallel direction with respect to the IAN position and running, in order to minimize nerve compression; * post-extraction residual bone cavity inspection using a Zeiss 4x300 magnification optical system to better identify intra-operative nerve exposure. No material was inserted into the residual cavity, neither by regeneration nor by haemostasis. After one week, sensitivity was tested on both sides with the tactile test using a 27-gauge needle tip and, if a difference was found, the patient was followed up once a week for the first month and every two weeks thereafter, until he/she reported to perceive the pin-prick test in the affected side the same way as the healthy side.
