Candida albicans adherence on acrylic resin plates immersed in black tea steeping

Background: Black tea or Cournelia sinensis is one of known tea varieties in Indonesia. Actually, black tea is consumed daily as beverage that can function as antiseptics and fungicides. Black tea containing antibacterial and fungicide properties can reduce the number of Candida albicans (C. albicans) colony attachment on the surface of acrylic resin plates. Purpose: This study was done to determine the effective concentration of black tea steeping used as the immersion material of acrylic resin plates towards the number of Candida albicans colonies. Methods: In this study, acrylic resin plates with the size of 10 × 20 × 1 mm were immersed in black tea steeping with the following concentrations, 3.33%, 6.66%, and 13.33%, for one hour. The growth of C. albicans colonies were then detected by counting the number of colonies growing on Sabouraud’s dextrose medium. Data was analyzed by using both One-Way ANOVA with the significance level of 5%, and Tuckey’s multiple comparison tests (Tuckey’s HSD test). results: There were significant differences in the number of C. albicans colonies in acrylic resin plates immersed in black tea with the concentration of 3.33%, 6.66%, and 13.33%. Conclusion: It can be concluded that the higher concentration of black tea (13.33%) used to immerse acrylic resin plates, the greater the decreased number of C. albicans colonies.
