LLLT is effective in the treatment of denture stomatitis. Further placebo controlled studies are in progress.

Light from a low-power laser (LLLT) may be valuable in the treatment of DS. This is of great importance since the rate of recurrence of disease is high, whereas an optimal treatment modality has not yet been found.

Objective: The aim of this study was to quantitatively investigate the efficiency of the ultraviolet (UV) and visible light in eradication of Candida albicans in vitro; in particular, to determine, for selected wavelengths, the specific eradication coefficients and thresholds in terms of energy density levels required to effect 3.0log 10 and 4.0log 10 reduction. Background data: Oral candidosis is the most common infection of the oral cavity and is caused by Candida species. The widespread use of topical and systemic antifungal agents as conventional treatment for oral candidosis has resulted in the development of resistance in C. albicans. Therefore, it has become necessary to develop alternative therapies for the treatment of oral candidosis. Methods: C. albicans ATCC Ò 90028 Ô was irradiated with 254 nm, 365 nm, 406 nm, 420 nm, and broadband Xe spectrum. For each wavelength, a fit of experimental data (survival fraction vs. applied energy density) with an exponential decay function enabled estimation of the specific eradication coefficients and thresholds.
