Purpose : The aim of this study was to investigate the relationship between the changes in surface texture and the imbibition and volatilization of home reliners.Materials and Methods : The home reliners used in this study were Tafu Grip®, Polydent®, New Liodent®, and Cushion Collect®. Soft-Liner® was used as a control. The changes in the surface texture of the materials were observed using a stereoscopic microscope. Weight changes were measured to evaluate the imbibition and volatilization of these products after being kept in distilled water (37°C) and ambient air. After immersion, regression analysis was done. The relationship between the changes in surface texture and both imbibition and volatilization of the home reliners was investigated by canonical correlation analysis.Results : The surface texture of the home reliners tested changed rapidly after soaking when holes and grooves appeared. Soft-Liner® exhibited few changes. The amount of imbibition of the home reliners, except for Polydent®, increased with time, but the amount measured for Soft-Liner® decreased only slightly. The amount of volatilization of both the home reliners and Soft-Liner® increased with time. Results of the regression analysis showed that the coefficients of determination were highly significant in the quadratic equation. The result of the canonical correlation analysis indicated that there was a relationship between the changes in surface texture and volatilization of home reliners.Conclusion : Within the parameters of this study, it was learned that many grooves appear on a small number of ethanol-containing home reliners.
