Ozone use effect in dental whitening treatments.

Abstract

Introduction: The most commonly used methods for tooth whitening currently require the use of substances that have a high probability of generating undesirable effects, such as tooth sensitivity. Ozone has been widely used in dentistry due to its multiple benefits, including its oxidative capacity that allows it to act on the compounds that pigment teeth, thus obtaining a whitening effect. Objective: To conduct a systematic review of the literature to analyze the effect of using ozone in tooth whitening treatments. Materials and methods: A search was conducted for scientific articles published on the Internet using the PubMed, Science Direct, Google Scholar, and ResearchGate search engines. Results: 8 articles were analyzed, of which 4 compare the use of ozone with another substance for whitening, 2 evaluate the effectiveness of ozone in combination with another substance for whitening, 1 evaluates the effectiveness of ozone at different application times, and 1 evaluates the effectiveness of ozone in combination with a desensitizing gel. Conclusions: The use of ozone has a significant effect on the color of teeth and can be used as a tooth whitening agent. It produces a color change comparable to that obtained with other methods, in a similar application time. When used in conjunction with other methods, it enhances the whitening effect and minimises the risk of sensitivity. Ozone reduces the risk of presenting undesirable effects that are frequent when using other whitening methods.
