Evaluation of effect of topical ozone therapy on salivary Candidal carriage in oral candidiasis.

ABSTRACT

Background and Aim: Ozone is highly valued for various therapeutic applications such as antimicrobial, antihypoxic, analgesic, and immunostimulating for more than a century in the medical profession. Ozone therapy is now gaining a strong foothold in dentistry. Ozone has bactericidal, fungicidal, and virucidal properties. Oral candidiasis is one of the most common opportunistic fungal infections of the oral cavity. Hence, a study was conducted to evaluate and compare the ability of ozonated water and topical clotrimazole in reducing the Candidal species colony‑forming unit (CFU) count in oral candidiasis. Materials and Methods: The study included 40 candidiasis patients of either sex aged between 18 and 60 years attending the Department of Oral Medicine and Radiology. The patients were randomly assigned to either topical ozone therapy or topical clotrimazole groups. Salivary Candidal CFU counts were assessed during and after the treatments. Results and Conclusion: There was gradual but significant reduction in Candidal CFU count in both groups. At the end of the treatment, Candidal CFU count reduction in ozone group (60.5% reduction) was more than the clotrimazole group (32.3% reduction). 14 patients (70%) with candidiasis in ozone group were reduced to 6 (30%) whereas only 8 patients (40%) out of 13 (65%) in clotrimazole group, although intergroup comparison was not statistically significant. Ozone therapy was much more effective in reducing the patients with candidiasis to a state of carriers. These findings suggest that ozonated water might be useful to treat oral candidiasis.
