Objective: This study aims to evaluate ozone’s impact on initially formed enamel caries before applying silver diamine fluoride, utilizing a Vickers microhardness tester as the excitation source. Material and Methods: Sixty premolars were exposed to demineralization to form artificial incipient caries. Then, the teeth were arbitrarily distributed among four investigational groups (group 1 received silver diamine fluoride, group 2 received ozone, group 3 received ozone then silver diamine fluoride, while group 4 received no treatment as a control group). Enamel microhardness was evaluated at three stages: before exposure to demineralization solution, after exposure, and following treatment using a Vickers microhardness tester. A one-way ANOVA test was utilized to calculate the difference in microhardness values across the four groups, followed by Tukey’s test and paired t-tests were accomplished before and after treatment. 5% was established as the significance level. Results: The data shows a clear and statistically significant difference in surface microhardness between the control and experimental groups. Tukey’s test indicates that Group 3 and Group 1 did not have a significant difference. However, paired t-tests conducted before and after treatment revealed significant differences in the experimental groups, while non-significant differences were found before and after in the control group. Conclusion: This investigation disclosed that SDF is still an excellent option whereas ozone alone has no impact on remineralizing enamel incipient caries, and there is no advancement in combining both approaches.
