Abstract：Objective:Comparison of three kinds of cleaning methods of oral activities,the color of denture resins,surface roughness,value of water absorption and solubility,bending strength performance impact.Methods:45 rectangular samples were prepared from heat-curing denture base resin accoding to ISO YY0270-2003.The samples were randomly divided into three groups.They were immersed in clear water (group A),Polident denture cleansers (group B),toothpaste and toothbrush brushing(group C).Then,the surface roughness(Ra),color change(AE),surface morphology,flexural strength,water absorption and solubility of the samples were detected.Results:The change of color of the three groups was statistically significant (P＜0.05).Obvious cracks and scratches can be observed on the surface microstructure of the C group.There was significant difference in Ra value between the C group and the other groups (P＜ 0.05) There was no significant difference in bending strength,water absorption and solubility between the groups.Conclusions:The use of toothpaste,toothbrush in the methods of 3 kinds of denture cleaning scrub on the resin surface roughness of specimen has a certain effect.Polident denture cleansers did not influence the color stability,surface roughness,flexural strength,water absorption and water solubility.
