Abstract
INTRODUCTION: The aim of the present investigation was to study the effect of local infiltration of corticosteroids on postoperative pain and quality of life (QOL) in teeth with irreversible pulpitis after 1-visit endodontic treatment. METHODS: In this double-blind randomized clinical trial, 242 healthy patients with irreversible pulpitis undergoing 1-visit endodontic treatment were included. Forty-five patients were lost during the follow-up, and the remaining 197 patients were followed for 7 days (67 patients in the placebo group, 66 in the long-acting betamethasone group, and 64 in the dexamethasone group). The patients marked their level of pain and QOL before treatment and at 6-, 12-, 24-, 48-, and 72-hour and 7-day postoperative intervals using a questionnaire. Freidman and Kruskal-Wallis tests were used for statistical analysis. P ≤ .05 was considered significant. RESULTS: The pain was more severe in the placebo group compared with the other groups at all time intervals. A significant increase was observed in pain severity after 12 hours in all 3 groups. In general, the pain was less severe in the dexamethasone group compared with the betamethasone group at 6-, 12-, and 24-hour intervals. The pain severity was similar in both groups at 48 hours, and it was less severe in the long-acting betamethasone group compared with the dexamethasone group after 72 hours and 7 days. There were no significant differences in the betamethasone and dexamethasone groups in pain intensity between males and females. Moreover, overall pain perception was higher in the mandible than in the maxilla. There was an inverse and significant relationship between pain severity and QOL. CONCLUSIONS: Infiltration of long-acting betamethasone and dexamethasone resulted in decreased postoperative pain experience. Dexamethasone was more effective in alleviating pain within the first 24-hour period after treatment. Infiltration of long-acting betamethasone and dexamethasone exhibited the same efficacy in 48 hours. The efficacy of long-acting betamethasone in pain relief lasted for 7 days. The QOL in the 2 groups receiving corticosteroids was higher than that in the placebo group.
