Comparison of microorganism accumulation on polyamide versus different polymethylmetacrylate denture base materials

15594

Purpose: The purpose of this study was to compare the microorganism accumulation of polymethylmethacrylate and polyamide denture base materials manufactured by different companies. Materials and methods: Specimens (n=7 per group) of 3 different denture base materials (Deflex, SR-Ivocap, Meliodent), a total of 21 specimens, were prepared with dimensions of 3x10x10 mm3 according to the manufacturers recommendation and steriled by ethylen oxide gas sterilization. Streptococcus mutans and Candida albicans, the most common microfilm bacteria and the most common cause of denture stomatitis, respectively, were investigated in this study. Following the Mc Farland settings of microorganisms, separate tubes with known number of microorganisms were prepared. The specimens were kept in tubes for 15 minutes and dried on sterile papers in a sterile cabinet for 30 minutes. Then, specimens were placed in tubes containing sterile water and vortexed to let the microorganisms free in sterile water. 0.01mL of contaminated water was taken using micropipette and inoculated on blood agar medium for S.mutans and SDA (saburoud dextrose agar) for C.albicans and kept in incubator for 1 day at 37 °C. Following the incubation period, colony counts were made. Results: Colony counts showed that there was not a significant difference between microorganism accumulation (S.mutans and C.albicans) on polymethylmethacrylate (SR-Ivocap ve Meliodent) and polyamide (Deflex) denture base materials. Conclusion: Polyamide denture material may be a good alternative to polymethylmetacrylate from microbiological aspect. It should be taken in to consideration that in addition to the microorganism accumulation there are parameters that needs to be considered for denture base materials.
