Abstract

This study was conducted to compare the efficacy of primary and secondary closure techniques after surgical removal of impacted mandibular third molar. A total of 200 patients (aged 17–30 years) were divided into two matched groups – Group I (n=100), managed by repositioning of flap to obtain primary closure, Group II (n=100), by removal of 6–7mm wedge of mucosa adjacent to the second molar to obtain secondary closure. Comparison was done at postoperative days 1, 3, 7, 15 and 30 using Student “t”-test. Preoperatively, no significant difference was observed between two groups for pain score, swelling, and mouth opening. Mean pain score and mean swelling were significantly lower in Group II as compared to Group I while mean mouth opening was significantly higher in Group II as compared to Group I on postoperative day one. Comparable pain, swelling and mouth opening in both the groups were achieved on postoperative day 7 onwards. The results in present study favor the secondary closure of socket as it causes lesser postoperative swelling and pain as well as early improvement in mouth opening.
