This single centre 5 year prospective study reports the incidence of impairment of inferior alveolar nerve ( IAN) and lingual nerve sensation following the removal of impacted lower molars and investigates the relationship between nerve damage and age, depth and type of impaction, gender, surgical technique, time taken, raising of the lingual flap during surgery and grade of staff and assistant. The study covers 246 patients who had 261 wisdom teeth removed. The patients were unselected for age, gender or social class.

Impairment was determined by direct questioning of the patients. After 7 days the incidence of lingual nerve impairment was 2.0% percent. The incidence of inferior alveolar nerve impairment was 2.8% percent. No permanent nerve damage was recorded. The study suggests that lingual and inferior dental nerve paraesthesia were related to the type of impaction, degree of difficulty and not sectioning the tooth.
