Abstract

Aim: To investigate the effect of diode laser on the Candida albicans colonization in complete denture patients. Methods: A total of 40 complete maxillary dentures wearers studied in this cross-sectional study. Dentures were then randomly divided into two groups. In first group as the control group no intervention was made. Dentures of the second group merely exposed to laser irradiation by the diode laser with wavelength of 940 nm with 100mW for 30 seconds on mucosal surface of dentures before delivery. Samples were collected from the mucosal surface of upper dentures on the determined days. All collected colonies were counted. Clinical outcome was evaluated regarding the colonization of Candida albicans reported by CFU. Difference of colony counts results between two groups was evaluated by Mann-Whitney test. Statistical significance was assumed if p<0.05. Results: The results showed laser irradiation was significantly effective in reducing candida colonization. The lower density of the colonies was seen in laser group in compare with control group on 15th and 60th days after denture delivery (P=0.002) & (P=0.003), respectively. Conclusions: generalization our data into the clinical setting, it can be proposed that a direct laser-based approach can significantly reduce the colonization of Candida albicans. It can also be concluded that laser light at specific wavelengths could be a possible promising novel strategy for prevention of denture stomatitis. © 2021 Lahore Medical And Dental College.
