Abstract
Introduction: The action of ozone is associated with the prevention of dental plaque formation, and the reduction of bacterial development supports the prevention of dental caries. This paper aims to establish the effect of gaseous ozone on developing new caries lesions two years after its application for caries-active patients. Material and Methods: Patients aged 30 to 50 were selected with no common diseases. They all have five or more caries on the teeth, without missing teeth. Patients were divided into two groups of 10 participants. One group had ozonation of all teeth, and another is a control group without ozonation. Results: After two years, the number of caries lesions in the group without prophylactic ozonation is more significant. The results showed that the patients in the ozonation group had significantly fewer primary caries than those in the control group( p≤0.0001). Conclusions: Repeated ozonation of all teeth according to the applied methodology (10 times, distributed twice a week by 24 seconds exposure to ozone in a gaseous state) has a caries-protective effect against new caries lesions.
