Prediction of Risk Factors Associated with the Severity of Pain Following Impacted Lower Third Molar Surgery: A Prospective Study

Objective: The main object of this study was to evaluate all the predicting variables that may influence the intensity of pain after surgical removal of lower third molar. Methods: In this prospective cohort study 159 consecutive cases in which removal of impacted lower third molars were evaluated. Twenty three groups of variables that may affect the severity of pain after mandibular third surgery have been studied. The intensity of pain was measured on the 1st and 2nd days and 1st and 2nd week postoperatively, by asking the patient to rate the nociceptive experience on a visual analogue scale (VAS) at each time respectively. Results: Pain was reported to be most intense during in first postoperative day, and then there was a drop in mean pain intensity on each subsequent postsurgical extraction days Conclusion: The intensity of pain was highly significant correlated to the operative trauma of the contentious issue
