Abstract

The aim of this systematic review was to determine whether bromelain is an effective drug for the control of pain and inflammation associated with third molar surgery. Randomized, controlled clinical trials on the subject were identified through a systematic search of the literature using the PubMed/MEDLINE, Scopus, and Cochrane Library databases. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two independent, blinded reviewers selected studies based on the inclusion criteria. Divergences of opinion were resolved by consensus. A meta-analysis was performed for the outcomes pain and trismus and was based on the inverse variance method for continuous outcomes, considering the mean difference (MD) and corresponding 95% confidence interval (CI). A total of 186 articles were initially retrieved from the databases. After the different stages of the selection process, five articles reporting data for a total 252 patients remained and were included in the review. Bromelain proved to be effective at controlling postoperative pain at 48–72 h after surgery (P = 0.03; MD −0.89, 95% CI −1.70 to −0.09), but did not achieve a significant effect in comparison to the control group with regard to oedema or trismus.
