Abstract

Introduction

Endodontic pain is a symptom of pulpal and/or periapical inflammation. One strategy for pain reduction is using medications, such as dexamethasone. A definitive protocol for preventing and controlling pain caused by irreversible pulpitis during endodontic treatment has not yet been established. This is a systematic review to answer the following question: is the use of dexamethasone effective in controlling pain associated with symptomatic irreversible pulpitis?

Methods

This study was registered in the PROSPERO database (CRD42017058704), and Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement recommendations were followed. MEDLINE, Scopus, ScienceDirect, Web of Science, Latin American Caribbean Health Sciences Literature, Cochrane Library, and Google Scholar databases were used in our research. No restrictions were applied to dates or language of publication. All records identified electronically were organized and evaluated by 2 independent authors, and, in case of doubt, a third author made the decision. The Cochrane Collaboration tool was used. The data were analyzed with RevMan 5 software (The Cochrane Collaboration, Copenhagen, Denmark), and data from eligible studies were dichotomous (with and without pain).

Results

A total of 4825 studies were identified. After screening, 523 studies were selected, and, after careful evaluation, only 5 articles remained. All meta-analyses revealed a global effect (P < .05, P < .05, and P < .05), which means that 4 mg dexamethasone helps relieve pain, sometimes for up to 8, 12, and 24 hours.

Conclusions

The pain felt by patients diagnosed with symptomatic irreversible pulpitis may be alleviated by administering 4 mg dexamethasone either by mouth or through intraligamentary and mainly supraperiosteal injections into the root canal for up to 24 hours.
