Risk Factors for Less Common Postoperative Complications Following Surgical Extraction of Mandibular Third Molar: A Prospective Cohort Study

Abstract

Background: The less common postoperative morbidity following third molarsurgery such as inferior alveolar nerve paresthesia, lingual nerve paresthesia,adjacent tooth injury and post-perative bleeding is affected by a number of riskfactors.Material and methods: In this prospective randomized study 159 consecutive casesin which removal of impacted lower third molars in 107outpatients wereevaluated. Five groups of variables have been studied which are regarded as apotential factor for one or more than one complication after mandibular thirdremovalResults: The incidence of inferior alveolar nerve paresthesia, lingual nerveparesthesia, adjacent tooth injury and post-operative bleeding is addressed withlocation of the most significant risk factors.Conclusions: It was found that the difficulty of surgical extraction and the operationtime are the main high significant risk factors; sex and smoking aren’tsignificant factors for any complication. The oldest age group has a littlestatistics significant differences.Background: The less common postoperative morbidity following third molarsurgery such as inferior alveolar nerve paresthesia, lingual nerve paresthesia,adjacent tooth injury and post-perative bleeding is affected by a number of riskfactors.Material and methods: In this prospective randomized study 159 consecutive casesin which removal of impacted lower third molars in 107outpatients wereevaluated.
