Comparison of Candida albicans colony amount in heat-cured acrylic and thermoplastic nylon resin after immersion in Ulee Kareng coffee (Coffea robusta)

[摘要] Introduction:Heat-cured acrylic resin is the most often used material in the manufacture of denture base. Along with the development of science and technology, to overcome the shortcomings of heat-cured acrylic resin, repairment of denture base material was done, one of them is a thermoplastic nylon resin. On the use of denture often foundCandida albicansattached to the denture. This study aimed to determine the comparison of the amount ofCandida albicanscolony on heat-cured acrylic and thermoplastic nylon resin after immersed in theUlee Karengcoffee(Coffea robusta). Methods:The number of specimens in this study were 8 specimens; 4 Meliodent® heat-cured acrylic resins and 4 Bio Tone® thermoplastic nylon resins with size of 10x10x2 mm. The methods of this study was experimental laboratory. The specimens were stored in a solution ofUlee Karengcoffee(Coffea robusta)for 7 days. Each specimen was contaminated withCandida albicans,then the number ofCandida albicanscolony was counted with Colony counter, from threshing results of heat-cured acrylic and thermoplastic nylon resins .Data were analyzed with unpaired t test.Results:Unpaired t test results showed that there were significant differences (p<0.05) between the number of colonies ofCandida albicansin heat-cured acrylic resin (4.5 CFU/ml) and thermoplastic nylon resin (1.5 CFU/ml) after both immersed in theUlee Karengcoffee(Coffea robusta). Conclusion:The amount ofCandida albicanscolony on heat-cured acrylic resin was higher than on thermoplastic nylon resin.
