不同消毒剂对义齿基托树脂性能影响的研究
Comparison of the effects of different disinfectants on the properties of denture base resins
摘要
Abstract
Objective:To compare the effects of four kinds of disinfectants on the properties of denture base resins.Methods:Seventy-five rectangular samples were randomly divided into 5 groups(each group of 15 samples)that were immersed in running water(group A),0.12% chlorhexidine(group B),75% alcohol(group C),Polident denture cleanser solution(group D),and 0.5% iodine volts soak(group E),respectively.The surface roughness(Ra),color change(ΔE),surface morphology,flexural strength,water absorption and solubility of the samples were detected.Results:The color(ΔE)and surface roughness(Ra)of group B,E changed significantly,compared with group A(P<0.05).Obvious cracks can be observed on the surfacial microstructure of the group C,compared with other 4 groups(P<0.05).Group E exhibited obvious dyeing,and group B showed minor dyeing.Group C showed significant water absorption and solubility value,compared with group A(P<0.05).There was no significant difference in bending strength among all groups.Conclusion:Polident denture cleanser showed least effects on the color stability,surface roughness,flexural strength,water absorption and water solubility of denture resins,and could been recommended for denture cleaning.关键词
