Abstract: Objective To evaluate the colour stability, surface roughness and ?exural strength of heat-curing denture base resin after using five denture cleansers. Methods Samples were prepared from heat-curing denture base resin and immersed in Polident, Victoria-C,Protefix,0.2% chlorhexidine gluconate ,Y-Kelin denture cleansers and distilled water. The color changes (ΔE), the roughness and the ?exural strength were then measured. Results The color changes were significantly greater in the 0.2% chlorhexidine gluconate ,Y-Kelin denture cleansers than in the control group. The ΔE values quanti?ed by the NBS (National Bureau of Standards) were classi?ed as Slight in all groups. When comparing the surface roughness and ?exural strength, no statistically significant difference was found among the different immersion procedures. Conclusion Immersion in 0.2% chlorhexidine gluconate and Y-Kelin denture cleansers influenced the color stability of heat-curing denture base resin after a 180-day use, but it was clinically acceptable. Polident, Victoria-C, Protefix did not influence the properties.
