This study evaluates the effect of coatings on bacterial adhesion on denture acrylic and the wear of denture teeth.
Denture stomatitis is a prevalent disease among removable denture wearers. The cause of this disease stems from a myriad of factors including host immunity and poor oral hygiene. Denture acrylic material is very conducive for the growth and adhesion of bacteria because of its porous nature. The application of plasma enhanced chemical vapor deposited (PECVD) coatings on the surface of acrylic dentures can produce a less porous surface which may minimize the adhesion of bacteria and therefore colonization. The goal is the application of these coatings will help minimize the occurrence of denture stomatitis. Another issue of removable dentures is the low wear resistance of denture teeth. The application of these coatings on denture teeth should minimize wear of these teeth and prolong the life of removable dentures.

SiO2/SiC coatings will be applied to the surface of removable partial dentures and denture teeth.
University of Florida
Gainesville, Florida, United States
Change in Bacterial Count
Biofilms on the tissue surface of the dentures will be obtained for the aforementioned time intervals. Biofilm counts will be analyzed to determine the effect of the coatings on the number of disease causing bacteria on the surface of the denture
Time frame: 2,4 and 12 weeks
wear of denture teeth
Denture teeth will be analyzed for wear at 6 months to determine the effect of PECVD coatings on the wear of denture teeth.
Time frame: 6 months
