Aim: This study aims to evaluate and compare the effect of using three commercially available denture cleansers on surface color, surface roughness, and flexural strength of heat-cured resin. Materials and methods: A total of 80 rectangular heat-cured acrylic specimens were fabricated and all were immersed in denture cleansers over a period of 6 days in which 30 immersions were performed. Then the physical properties of the heat-cured resin were tested using portable colorimeter, universal testing machine, and surface analyzer. The paired t test was done to compare the before and after immersion values for color, surface roughness, and flexural strength in denture cleansers. The post hoc test was performed to make multiple comparison among different groups. Results: All heat-cured resin bases presented with changes in color, surface roughness, and flexural strength to some extent when immersed in all the three denture cleansers. The values of change in color, surface roughness, and flexural strength were higher when immersed in Clinsodent as compared to all other groups. Conclusion: The changes observed in color and surface roughness of all resins samples were within the clinically accepted range while significant decrease in flexural strength was seen on immersion in all three denture cleansers; least change was observed with the Secure denture cleanser.
