Device A was tested on denture-wearing patients in a clinical study, with samples collected from mucosal surfaces before and after irradiation to assess microbial CFUs (colony forming units). Devices A, C, and D significantly reduced <em>C. albicans</em> and <em>S. aureus</em> on plates with the inoculated surface facing upward, while device F showed a slight reduction when the inoculated surfaces were facing downward. Devices A and D eliminated <em>C. albicans</em> on contaminated dentures in vitro. Device A reduced all microorganism CFUs on denture surfaces in clinical studies.
