Efficacy of Ketorolac Tromethamine Diluted Saline Irrigant on Postoperative Sequelae in Patients Undergoing Lower Third Molar Impaction Surgery: A Prospective Clinical Study.

ABSTRACT

Background Lower third molar surgery is very commonly performed for minor oral surgery by an oral and maxillofacial surgeon. One of the main chief complaints that patients report back to the clinic after getting their lower third molar impaction surgery is immediate postoperative pain. In our study, we have compared the efficacy of ketorolac tromethamine diluted saline solution over plain saline solution used as an irrigant in reducing postoperative swelling and pain. Aim The aim of the current study is to analyse the efficiency of ketorolac tromethamine diluted saline solution over normal saline without any drug dilution in reducing postoperative sequelae like pain and swelling after surgical removal of the lower third molar. Materials and methods This study was carried out at the Department of Oral and Maxillofacial Surgery, Saveetha Dental College and Hospital, Saveetha Institute of Medical and Technical Sciences (SIMATS), Saveetha University, from April 2023 to July 2023. The study included 50 individuals who wanted to prophylactically get the lower third molar removed surgically. These participants were divided into two groups. One group received ketorolac diluted saline irrigant while the other group received plain saline (0.9% NaCl) as irrigant. Postoperatively, pain and swelling were evaluated in both groups. Both pain and swelling were measured preoperatively, postoperatively after 48 hours, and postoperatively after seven days. The swelling was measured using a 4-point measuring scale, and pain measurement was done using a 10-point visual analogue scale. Statistical analysis was done using Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 23.0, Armonk, NY). For the comparison of continuous variables between the two groups, an unpaired t-test was used. The normality of the results obtained was checked using the Shapiro-Wilk test. The results were considered statistically significant if the P-value was less than 0.05. Results Based on the results obtained it was found that participants who were included in the ketorolac saline group had comparatively lower postoperative pain scores than participants in the plain saline group and this was statistically significant (P=0.001). Postoperative swelling was also comparatively lower in the ketorolac tromethamine saline group but the results were not statistically significant at the end of day 7 (P=0.09). Conclusion Upon observing the cumulative results obtained, we conclude that ketorolac saline (10mg/100mL) was more efficacious in terms of pain reduction than the regular saline solution in impacted lower third molar surgery.
