• Abstract:

  Background: this systematic review and meta-analysis aims to address the issue of PICOS: Is there evidence to indicate the use of cryotherapy and heat therapy after surgical extraction of impacted third molars? Methods: electronic searches in the databases were performed according to the PICOS strategy from 01/01/1990 to 12/31/2018, complemented by a manual search. Studies that showed data on the post-operative anti-inflammatory benefits of cryotherapy and heat therapy (regarding extraction of impacted third molars) were included. Results: of the 271 citations, 11 articles were selected for evaluation. Ten addressed the effects of cryotherapy, with only one referring to thermotherapy. Of these, five trials were suitable for meta-analysis, all concerning cryotherapy. This analysis indicates, a reduction in postoperative sequelae such as pain, trismus and edema in the groups where cryotherapy was applied, although meta-analysis has only found statistically significant results for the reduction of pain after surgery in the groups which applied ice. Conclusions: Additional Randomized Controlled Trials are required and should concentrate on the development of modes, duration and frequency of the application of ice and heat.
