Abstract

Introduction: Denture disinfection is not taken seriously because patients are unaware of the effects of contaminated prostheses on systemic conditions. Among different methods of physical disinfection, ultraviolet (UV) light disinfection has a definite future because of the nondestructive nature of UV light on removable acrylic dentures. Aim: This study aims to “evaluate microbial contamination and compare the efficiency of UV disinfection of acrylic removable dentures with the conventional method of disinfection on contaminated dentures.” Materials and methods: In this study, 45 patients with complete and removable partial dentures were selected and subjected to three different disinfection methods. Group I—UV light-emitting diode (LED) disinfection (wavelength 254 nm) for approximately 300 seconds; group II—brushing with dentifrice; and group III—brushing with tap water for approximately 15–20 strokes. Pre- and postdisinfection microbial swab samples were collected, and the microbiological load in CFU/mL was determined for each sample. Specific microorganisms from the isolated colonies were also identified and analyzed. Results: According to the statistical analysis, there was a positive correlation between pre- and postdisinfection within the groups of disinfection (group I—UV light LED disinfection and group II—brushing with a dentifrice, but not within group III—brushing with tap water). Conclusion: A comparison of UV light disinfection with the other conventional disinfection methods shows a significant reduction in contamination, as measured by postdisinfection microbial colonies, and is comparable with brushing with dentifrices but not with brushing with tap water. Clinical significance: This study provides insights into the efficiency of UV light denture disinfection.
