Aims: The aim of the present study is to investigate the relationship between preoperative findings and the postoperative outcome following surgical removal of lower third molar. Settings and Design: This is a prospective observational study conducted at the Department of Oral and Maxillofacial Surgery, Saveetha University. A total of 104 patients requiring surgical removal of unilateral third molar were evaluated. Patients who were on antibiotics and analgesic for an underlying problem related to impacted third molars preoperatively were excluded. Preoperative variables evaluated were age, sex, maximum interincisal distance, facial measurements both vertical and horizontal, radiographic measurement of position, class, angulation of impacted lower third molar, experience of operator, and duration of surgery. Postoperative evaluation was done on the 1st and 4th day and 7th postoperative day, and the following parameters were evaluated: facial swelling, pain, dry socket, secondary infection, paresthesia, postoperative bleeding, and fracture of jaw. Statistical Analysis Used: The preoperative parameters and postoperative outcomes were compared and correlated using one-way ANOVA, independent “t” test, and Chi-square test. Results: There is statistically significant result to demonstrate that pain and swelling increase with age, the depth of impaction, and when there is no adequate available space between the anterior border of ramus and second molar. As duration of surgery increases, pain, swelling, trismus, and frequency of dry socket increase in our study. Frequency of dry socket increases with increased depth of impaction. Conclusions: In our study, age, sex, the depth of impaction, the space available for the impacted tooth between the anterior border of ramus and second molar, duration of surgery, and horizontal and distoangular impactions have a positive correlation with the outcome of surgical removal of third molar.
