Abstract

Objective: Denture cleaning is important for oral hygiene in patients using dentures. Today, there are various commercial products used for denture cleaning. The usage methods and durations of these products are different. This study aimed to investigate the antimicrobial effectiveness of alkaline peroxide group disinfectant solution on dentures. In the study, dentures of 20 patients were kept in alkaline-based disinfectant for 3 and 10 minutes. Samples taken from different areas of the denture just before the denture was placed in the disinfectant and at the 3rd and 10th minutes after placement were evaluated microbiologically. The results obtained were evaluated according to the denture material, waiting time and the region where the sample was taken. A significant decrease in bacterial density was observed in dentures kept in alkaline disinfectant solution for 3 and 10 minutes depending on time. It was observed that the disinfectant effectiveness varied according to the denture material and a significant decrease in bacterial density and diversity was observed in polymethylmethacrylate dentures. In our study, it was observed that the 3-minute period preferred for chemical disinfection of dental prostheses in tablet immersion was not sufficient for disinfection, and that the disinfectant effectiveness would increase if this period was increased. It was also observed that the structure of the material used in the prosthesis should be taken into consideration when determining the disinfection method.
