The effect of photocatalyst effect of titanium dioxide anatase on heat polymerized acrylic resin plate towards the growth of Candida albicans colonies

Pengaruh efek fotokatalis titanium dioxide anatase pada plat resin akrilik polimerisasi panas terhadap pertumbuhan koloni Candida albicans

Abstract

Background: In general, removable denture are made from polymethyl methacrylate (PMMA) resin as the base material. This material has a drawback, namely that it is often attached to micro-organisms such as the fungus Candida albicans. Nanoparticle materials such as titanium dioxide (TiO₂) have antimicrobial properties, especially against C.albicans because it has photocata-lytic properties that can inhibit the growth of C.albicans colonies. Objective: To determine the effect of applying titanium di-oxide to heat polymerized acrylic resin (HPAR) plates towards the growth of C.albicans colonies. Methods: A true experimen-tal laboratory study using the HPAR plate as the object of research which was divided into the control group and the 1%, 2%, and 3% titanium dioxide-added groups. Data were analyzed using one-way Anova Welch. Results: There was an effect of add-ing titanium dioxide on the base of HPAR RD towards the growth of C.albicans colonies. Statistical tests showed significant re-sults (p=0.000; <0.05)). In the test between the titanium dioxide 1%, 2%3% and control groups, there were significant diffe-rences. Conclusion: The application of titanium dioxide to the base of HPAR RD reduced the growth of C.albicans colonies.
