Assessment of the ozone-mediated killing of bacteria in infected dentine associated with non-cavitated occlusal carious lesions.
The ability of ozone to kill micro-organisms associated with non-cavitated occlusal caries was investigated. The occlusal surfaces were treated with ozone (n = 53) or air (n = 49) for 40 s, and the underlying infected dentine was exposed. There was no significant difference between the number of bacteria recovered from the ozone-treated and the control sites (p > 0.1). Treatment of the exposed dentine with ozone resulted in a just significant (p = 0.044) reduction in bacterial counts. Ozone treatment of non-cavitated occlusal lesions for 40 s failed to significantly reduce the numbers of viable bacteria in infected dentine beneath the demineralized enamel.
