Comparison of Efficacy of Coumarin and Chymotrypsin/Trypsin in Patients Undergoing Surgical Removal of Lower Third Molars: A Prospective Study.

ABSTRACT

Background Third-molar surgeries are very commonly done by oral and maxillofacial surgeons. Pain and swelling that is associated with this procedure is a frequent reason for the patient's discomfort and apprehension. There is a need to look for a drug that can substantially reduce postoperative swelling amongst the patients. Pain, swelling, and trismus are common complications that are encountered after third molar surgery. These complications have a major impact on the quality of life of patients undergoing minor surgical procedures. Aim The aim of this study was to compare the effectiveness of coumarin and trypsin/chymotrypsin in the reduction of postoperative sequelae for mandibular third molar surgeries. Materials and methods The research was carried out at Saveetha Dental College and Hospital in the Department of Oral and Maxillofacial Surgery. The study consisted of 50 individuals, 25 individuals received tablets of coumarin, and 25 individuals received tablets containing a combination of trypsin/chymotrypsin postoperatively. Patients were evaluated postoperatively for pain and swelling. Postoperative pain was measured on days one, three, and seven after surgery using a visual analog scale. The postoperative swelling was measured on postoperative days three and day seven via a four-point technique. Data were analyzed using IBM SPSS Statistics for Windows, Version 23 (Released 2015; IBM Corp., Armonk, New York, United States). P-values less than 0.05 were considered statistically significant. The independent samples t-test was used to compare the outcomes between the two groups. Results It was found that study participants in the trypsin/chymotrypsin group reported statistically significantly less pain postoperatively than participants receiving coumarin (p=0.001). There was more reduction in swelling postoperatively in patients who were given trypsin/chymotrypsin as compared to the participants who were given coumarin, and the results were statistically significant. Conclusion Based on the data obtained, it can be inferred that the trypsin/chymotrypsin combination was more effective in reducing postoperative sequelae like pain and swelling than coumarin in the mandibular third molar surgeries.
