Abstract

Objectives: Effective management of post-endodontic pain is crucial for patient comfort. Although ketorolac is used for this purpose, its efficacy relative to other analgesics remains uncertain. This study systematically assesses evidence from randomized clinical trials that investigate the comparative effectiveness of ketorolac and other analgesic agents for the control of post-endodontic pain.

Material and methods: This study conducted a comprehensive search across several databases, including PubMed, Web of Science, ScienceDirect, Cochrane Library, Embase, Scopus, SinoMed, CNKI, Webvpn, and Wanfang Data. Search deadline was around August 2025. The study employed the inverse variance approach and a random effects model to analyze continuous data, utilizing the standardized mean as the comprehensive effect indicator. For dichotomous data, this study applied the risk ratio (RR), fixed-effect analysis model, and Mantel-Haenszel statistical methods.

Results: Our database search identified 386 potentially relevant studies. Ultimately, seven studies were selected for qualitative analysis, and five were chosen for quantitative analysis. The qualitative assessment indicated that five studies favored ketorolac, one study reported similar analgesic effects between ketorolac and alternative medications, while one study concluded that ketorolac was less effective. The quantitative analysis demonstrated a statistically significant difference in the analgesic effect of ketorolac…
