Abstract
OBJECTIVES
To conduct a systematic review and meta-analysis to assess the effectiveness of ozone therapy in oral ulcers healing when compared to placebo or active treatments.
MATERIALS AND METHODS
The search was carried out using PubMed, EMBASE, Scopus, and Lilacs databases. Clinical trials involving human participants were included. The Risk Ratio (RR) and the standardized mean difference (SMD) with 95%CI (confidence interval) were calculated. The ROBINS-I (risk of bias in non-randomized studies of interventions) and RoB2 (risk of bias tool for randomized trials) assessment tool was used to detect bias.
RESULTS
After the selection process, 12 studies were included. The meta-analysis showed that ozone therapy helps to reduce the size of the traumatic and autoimmune ulcers (RR=-0.44; 95% CI -0.71,-0.17; I2=0%) in comparison to placebo. Regarding pain reduction, ozone was superior to placebo (RR = 1.29, 95% CI -1.6 to -0.95); I2=0%), and equivalent to topical corticosteroid and laser photobiomodulation (RR = 0.26, 95% CI -0.27,0.78, p = 0.34).
CONCLUSION
Ozone therapy is an alternative for accelerating healing and reducing pain for both traumatic and autoimmune ulcers. However, the quality of evidence is limited.
CLINICAL RELEVANCE
Oral ulcerations are usually painful and impact quality of life requiring different approaches to boost wound healing and reduce symptoms. For this purpose, ozone therapy is a promising strategy.
