摘　　要：目的以浸泡法观察4种不同清洁剂对2种义齿基托材料被咖啡、红茶着色后的洁美效果。方法分别用咖啡、红茶浸泡着色热凝树脂、隐形义齿基托材料试件,再用1%NaClO、Efferdent、Polident partial、Polident overnight 4种清洁剂和水根据使用说明浸泡,如此反复12次,模拟使用清洁剂浸泡义齿12 d。采用白度色度仪测量试件在义齿清洁剂浸泡前后的颜色变化,观察清洁剂的洁美效果。结果咖啡与红茶对2种材料的着色差异有统计学意义(P<0.05);隐形义齿基托材料易于热凝树脂义齿基托材料被着色(P<0.05);各义齿清洁剂在每个循环阶段对试件洁美效果亦有统计学差异(P<0.05);试件的色差(ΔE)在不同时相的变化趋势也不同(P<0.05)。结论 1%NaClO、Efferdent、Polident overnight清洁剂洁美效果较好,Polident partial效果较弱。Objective To compare the staining effect of coffee and red tea to the different denture base materials,and to investigate the cleaning efficacy of four denture cleansers.Methods All samples were separately soaked in 1%NaClO、Efferdent、Polident partial and Polident overnight for 12 times within 12 days after staining by the coffee and red tea.Then,the color values of the samples were measured by the spectrocolorimeter.Results The staining effect between coffee and red tea in the two materials was statistically significant(P<0.05);the invisible denture materials are easily colored than heatcuring denture base resins(P<0.05);there was also a statistical difference in the cleaning ef?fect of the denture cleaning agents at each cycle stage(P<0.05);the trend is different in different phases of color difference(ΔE)(P<0.05).Conlusion Compared with the Polident partial,the cleaning efficacy of 1%NaClO、Efferdent and Polident overnight were better.
