Abstract

<p>Objective: The aim of this study was to evaluate and compare the activity of prescription and over-the-counter antimicrobial compounds against planktonic and biofilm forms of Candida albicans isolated from cases of oral candidiasis in vitro.</p> <p>Study design: The efficacy of azoles, polyenes, an echinocandin, and 4 over-the-counter mouthwashes were tested against C. albicans–derived planktonic and biofilm cells.</p> <p>Results: Planktonic cells were shown to be highly sensitive to all of the antifungal agents tested. Sessile cells were highly resistant to azoles (≥128 mg/L) but equally sensitive to caspofungin and short treatments with Corsodyl, Listerine, and Oraldene.</p> <p>Conclusions: Although C. albicans is sensitive to azole antifungal agents in planktonic form, it is highly resistant within the biofilm. The good efficacy of the over-the-counter mouthwashes against candidal biofilms in vitro suggests that clinical trials should now be designed to establish their role in the clinical management of oral candidal infections.</p>
