Use and Applicability of Ozone Therapy in Clinical Practice in Dentistry: An Integrative Review

Abstract

Ozone is a colorless gas with a characteristic odor present in nature in the form of trivalent oxygen. In 2015, the Federal Council of Dentistry (CFO/Brazil) approved the use of ozone therapy and in 2018 the Ministry of Health (MS/Brazil) approved the application of Ozone Therapy as a Complementary Integrative Practice in the Unified Health System. Therefore, the objective of this study was to verify the applicability of ozone therapy in dental practice. This is an integrative literature review whose search was performed in the Medline/Pubmed, LILACS, SciElo, and Google Scholar databases. Studies published in the last 5 years in English, Portuguese or Spanish were eligible. After the search, 312 titles were found and after exclusion of duplicates and analysis of abstracts and full text, 13 articles were included in this review. The literature reports the application of ozone therapy in several areas in the treatment of acute and chronic diseases. As a mechanism of action, ozone has a direct antimicrobial effect, immunoregulation, antioxidant defenses, analgesic, and vasodilator effects. In dentistry, its applicability is mainly in preventive dentistry and as a complement in surgical procedures, endodontic, and periodontal treatments.
