The Effect of Denture Cleansers on Color Stability, Water Sorption and Solubility of Stained Denture Base Materials

Background and Objectives: Denture cleanser is the most widely used method by patients to maintain clean healthy dentures but prolonged use of such cleansers may affect properties denture. The present study was carried out evaluate effect three prepared denture which were 4% citric acid, tartaric oxalic acid in addition Protefix a commercially available cleansers, on some mechanical physical (color stability, water sorption, solubility) acrylic resin (Stellon QC-20) flexible nylon (Vaplast) base materials after immersion tea solution. Methods: One hundred specimens (100) two equal major groups: Valplast. For each test properties, 50 prepared, 25 from Later on, divided into five groups, one group as control immersed distilled water, remaining 4 groups groups; immersing staining solutions for 10 days. studied compared with group. Results: Visual examination showed no color changes slight change valplast specimens. Valplast higher sorption solubility than acrylic. Conclusions: findings that equally effective, did not cause significant alteration tested properties. Except less stability.
