The article covered the function and results of ozone treatment in managing and preventing dental caries. Specifically, the author examined ozone and its benefits, including bactericidal, analgesic, antiinflammatory, and immunomodulatory effects. Ozonated water, ozonated olive oil, and ozone gas are forms of ozone used in dentistry. The authors provided examples of studies regarding the positive impact of ozone therapy on patients with caries. Also, the research authors described several effects of ozonated water, namely, disinfectant, anti-inflammatory, activation of intracellular metabolism of the oral mucosa and dental wounds, advancement of local blood circulation, provocation of regenerative functions, and hemostatic effect in capillary bleeding. The ozone generator and equipment for creating an ozone-oxygen (O3/O2) gas mixture were mentioned as required in dentistry to produce ozone.
