Abstract
Chemical denture cleansers have been considered to be an efficacious method to prevent denture plaque formation. However, daily use of those cleansers in clinical practice can damage soft denture lining materials. The purpose of this study is to evaluate the effect of two types of denture cleansers on sorption, solubility of soft denture lining materials at different time intervals. Twenty one specimens of the soft liners (silicon based) were prepared (50mm±1mm in diameter and 0.5mm ± 0.05mm in thickness) in dimension was distributed into three groups according to the immersion solution each group consist of seven specimens immersed daily as the following: Group 1: Samples immersed in distilled water for 24 hours (control group). Group 2: Samples immersed in alkaline peroxide (corega) for 15 min. denture cleanser solution. Group 3: Samples immersed in 4% citric acid denture cleanser solution for 10 minutes. The specimen were tested at different time intervals, specimens of sorption were tested after l and 3 weeks; while those for solubility were tested after 3 weeks only. The results of sorption of Ufi Gel soft lining in this study using (ANOVA) test showed that, there were high significant changes with the immersion time interval and the different immersion solutions used. Also the results of solubility using (ANOVA) test showed that a high significant difference among tested group after 3 weeks only. Generally; it is concluded that deterioration of soft liners in the denture cleansers appeared to be more significant with time.
