The aim of the study was to investigate different procedures to check for the most effective and most dimensionally accurate disinfection method for acrylic dentures.
Forty five edentulous patients wearing dentures were divided into three categories: Group I included disinfection with conventional microwave at 650 W for 3 mins twice a week, Group II disinfected their dentures by immersing in 0.2% clorhexidine gluconate solution for 30 mins twice a week and Group III used 100% White vinegar solution for immersion for 30 mins twice a week. The inter-molar distance, inter canine distance; the anterio-posteriro distance and the depth of the cast were measured with Digital Vernier calipers.
Group III showed highest decline in number of bacterial colonies after 60 days followed by Group I. Least decline was seen in II. Highest dimensional changes was seen in Group I followed by Group II dentures.
Within the limitations of the study, it was concluded that all the three methods were effective for disinfection of denture while immersion in White vinegar was most dimensionally stable.
