Outline of Final Research Achievements

In the current study, the effects of the modification of the denture surface were evaluated in vitro. The heat-polymerized acrylic resin for denture base, poly (methyl methacrelate) (PMMA) was used as the test material. It suggests that the surface of the specimens were smoother and hydrophobicity increased with this coating by using CVD methods. The result of antifungal test showed that about 50 % reduction in Cadida albicans viability was observed. In addition, the decrease of candida adhesion and the surface changing to the easy to separate the Candida plaque was observed. These results suggested that with the application of CVD, the easily-cleaned denture can be fabricated. It can be an useful technique to keep the denture wearer’s oral and physical health.
