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 molar
surgery such as inferior alveolar nerve paresthesia, lingual nerve paresthesia,
adjacent tooth injury and post-perative bleeding is affected by a number of risk
factors.
Material and methods: In this prospective randomized study 159 consecutive cases
in which removal of impacted lower third molars in 107outpatients were
evaluated. Five groups of variables have been studied which are regarded as a
potential factor for one or more than one complication after mandibular third
removal
Results: The incidence of inferior alveolar nerve paresthesia, lingual nerve
paresthesia, adjacent tooth injury and post-operative bleeding is addressed with
location of the most significant risk factors.
Conclusions: It was found that the difficulty of surgical extraction and the operation
time are the main high significant risk factors; sex and smoking aren’t
significant factors for any complication. The oldest age group has a little
statistics significant differences.
