Study Title:

Oral Bromelain for the Control of Facial Swelling, Trismus, and Pain After Mandibular Third Molar Surgery: A Systematic Review and Meta-Analysis.

Study Abstract

PURPOSE:
The purpose of this study was to evaluate whether bromelain can decrease trismus, pain, and facial swelling in patients undergoing impacted third molar surgery.

MATERIALS AND METHODS:
Three databases were searched to identify relevant studies through November 1, 2017. Randomized controlled trials (RCTs) that compared the effect of bromelain versus placebo after mandibular third molar surgery were included. The main outcome measures, pain, facial swelling, and trismus, were assessed in the early stage (2 to 3 days) and the late stage (7 days) after surgery. Standardized mean differences (SMDs) and weighted mean differences (WMDs) were calculated using fixed-effect models. All statistical analyses were implemented using Review Manager 5.3.

RESULT:
Six RCTs were included in this meta-analysis. The pooled results suggested that bromelain appears to be effective for decreasing facial swelling in the early and late stages after surgery (early-stage SMD, -0.24; 95% confidence interval [CI], -0.46 to -0.02; P = .03; late-stage SMD, -0.54; 95% CI, -0.84 to -0.24; P = .0004). Bromelain alleviated postoperative pain 7 days after surgery (SMD, -0.54; 95% CI, -0.87 to -0.20; P = .002), but there was no significant difference in pain levels at the early stage. For trismus, analyses showed that bromelain had no apparent effect on early or late trismus.

CONCLUSION:
Bromelain conferred moderate relief of postoperative discomfort after third molar surgery.
