Introduction: Surgical removal of the impacted mandibular
third molar is one of the most frequently performed surgical
procedures in oral and maxillofacial surgery. The purpose of
this study was to compare the primary and secondary wound
closure after surgical removal of impacted mandibular third
molars by evaluating the extent of facial swelling, the severity
of pain and degree of trismus.

Material and Methods: A prospective, randomized,
clinical trial was conducted in 80 patients. The patients were
randomly divided into two groups of 40 each. In Group 1:
patients underwent primary closure of the wound and in
Group 2: patients underwent secondary closure of the wound.
Postoperative pain, swelling, and trismus were evaluated on
the 2nd and 7th day postoperatively.

Results: Statistically significant difference was observed for
facial swelling and trismus on 2nd postoperative days between
both groups. Postoperative pain was less in the secondary
closure group.

Conclusion: From the outcome of the above study we can
conclude that the secondary wound closure technique has a
significant advantage over primary wound closure concerning
swelling and trismus.
