Online published on 13 November, 2019. Abstract Aim To evaluate the effect of Denture Cleansers on the properties of Conventional, High impact strength and Flexible denture base materials. Materials and Method A total of ninety disc shaped resin specimens (20mm×3mm) of different denture base materials [Trevalon Polymethyl Methacrylate (PMMA), Valplast and Trevalon HI (High Impact)] were prepared. Commercially available denture cleansers and the control were categorized into three groups [Group I-distilled water, Group II-0.5% Sodium Hypochlorite (NaOCl) and Group III-Daiso enzymatic cleanser] used for the immersion of these specimens. The physical properties like color stability, surface roughness and micro-hardness for each specimen was evaluated at the baseline and after six months. The data obtained was statistically analyzed using Repeated Measure Anova test and post-hoc test. Results There was significant change in color and micro-hardness among three denture base resins when immersed in cleansers from baseline to six months. The surface roughness of denture base resins was not within the clinically acceptable range. Conclusion The selection of denture cleanser should consider the duration of immersion, concentration of solution, temperature of the solution, material properties and its chemical composition.
