Subgingival distribution of yeast and their antifungal susceptibility in immunocompetent subjects with and without dental devices.

Yeasts colonize the subgingival biofilm, which becomes a reservoir that favors their reproduction. The purpose of the present work was to determine the prevalence of yeasts of the Candida genus in the subgingival biofilm of gingivoperiodontal disease patients, including users and non-users of dental devices, and their susceptibility to fluconazole and voriconazole. Samples of subgingival pockets of immunocompetent nonsmokers showing gingivitis and periodontitis were inoculated in a differential chromogenic medium.
