Abstract

Objective The study aims were to estimate the prevalence of neurosensory dysfunction (NSD) and identify risk factors for NSD after mandibular third molar (M3) removal. Study design In this prospective cohort study 864 patients had their M3 removed. Age, gender, surgeon's experience, and radiographic findings were recorded and the outcome variables were NSD and data analyses. Results In 884 patients, 1220 M3 were removed. Fourteen patients reported NSD postoperatively; 10 inferior alveolar nerve (IAN) injury, 3 lingual nerve (LN) and 1 had injury to both. After 5 years the number of patients with NSD of the IAN had decreased to 5, but no change in the LN. Conclusion Age and cortical line interruption were significantly associated with the risk of developing sensory dysfunction. All patients younger than 30, and 3 of 8 patients older than 30, had full recovery of the IAN injury. NSD of the LN persisted in all patients. © 2013 Elsevier Inc. All rights reserved.
