Antimicrobial Effect of Ozone Therapy in Deep Dentinal Carious Lesion: A Systematic Review

Abstract

Aim: This systematic review aimed to answer the following focused question: Is ozone therapy more effective in reducing microbial count as compared to conventional methods in deep dentinal carious lesion? Objective: The purpose of this systematic review was to perform a review on the effectiveness of ozone therapy in reduction of microbial count in deep dentinal carious lesion. Study eligibility criteria, participants, and interventions: The inclusion criteria comprised studies that compared effect on microbial count in deep dentinal carious lesion after treatments with ozone and other disinfectants in primary or permanent teeth in randomized clinical trials. Materials and methods: This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRIMSA) guidelines. The searched databases included Medline (via PubMed), Cochrane, and Google scholar. Articles published until 29 February 2020 without year restriction but only in English language were included. Results: The search resulted in 359 published studies. After removal of duplicate studies and full-text analysis, seven studies were selected. Overall, the results demonstrated the promising effects of ozone therapy in reduction of microbial count as compared to other disinfectant. Conclusions: Within the limitations of this review, it can be asserted that the ozone therapy is effective in reduction of microbial count in deep dentinal carious lesion. Clinical significance: Ozone therapy can be a useful tool to reduce the microorganisms in deep dentinal carious lesion.
