[Effect of premedication with celecoxib and gelofen on reduction of post-endodontic pain]

ABSTRACT

Non-steroidal anti-inflammatory drugs [NSAIDs] are the most common drugs prescribed for controlling and post root canal treatment pain. During the last decade, a new generation of NSAIDs has been introduced such as Celecoxib and Gelofen with less gastrointestinal side effects and more analgesic effect. No studies have been performed to compare Celecoxib and Gelofen with other NSAIDs considering the reduction of post-endodontic pain; therefore, this study was designed. In this randomized double blind clinical trial study, 90 patients were divided into 3 groups and underwent root canal therapy. Celecoxib, Gelofen, or placebo was randomized prescribed to the patients 1 hour before treatment. The intensity of pain was recorded using visual analog scale [VAS] at 4, 8, 12, 24, 48 hours after completion of root canal treatment. The data were analyzed by means of repeated measurements, multiple comparisons and one way ANOVA tests using SPSS software. P<0.05 was considered as the level of significance. The results showed significant difference between Celecoxib and Gelofen in comparison with placebo at 8 and 12 hours after initiation of treatment. There was no significant difference among three groups at 4, 24, and 48 hours after initiation of treatment [P>0.05]. According to the results, use of Gelofen or Celecoxib before treatment reduces post-endodontic pain. These drugs can be prescribed before initiation of treatment as the effective agents for reduction of post-endodontic pain
