Surgical extraction of lower 3 rd molar is the most frequent intervention in oral surgery. This procedure is often associated with significant post operative swelling that may have both biological and social implications. Various studies have been done using different anti inflammatory drugs to study their impact on inflammation.


This study was conducted on 110 patients who had undergone surgical removal of mandibular third molar. The subjects were divided into two groups by double blind method. In addition to post operative swelling and pain , trismus was evaluated using two different groups of drugs.


One group was administered 1 mg of dexamethazone every 8 hours for 3 days post operatively. The other group was administered 10 mg of serratiopaptidase every 8 hours for 3 days post operatively. Swelling, pain and trismus were assessed on the 1 st , 3 rd , 5 th and 7 th post operative days. The results of the studies were statistically analysed.


The results showed dexamethazone was more effective in reduction of swelling and pain in comparison with serratiopaptidase. Both dexamethazone and serratiopaptidase had the same effect on trismus.
