Each material was divided into 5 sub-groups (n=7) as two control and three test groups. Three test groups were immersed for 20 days in commercially available three denture cleansers (CO-Corega, PR-Protefix, VA-Valclean). Two-way analysis of variance and Tukey's post hoc HSD test were used to evaluate surface roughness and hardness data (alpha=0.05). Delta E, Delta L*, Delta a* and Delta b* mean values were used for ANOVA, Tamhane test was used as post hoc. Polyamides showed low hardness and high roughness before and after immersion. A significant decrease in hardness was observed for all resins except Rodex after immersion (p<0.05). The denture cleansers changed the roughness, hardness and color of some resins.en10.4012/dmj.2012-110info:eu-repo/semantics/openAccessDenture cleansersBase resinsPhysical propertiesPolyamide resinsPolystyrene graft copolymer resinsArticle32336737523718995Q1WOS:000322358300003Q3
