摘要: AbstractObjective. The purpose of this study was to determine the effects two denture cleansing methods on 3-D surface roughness, gloss and color base materials. Materials methods. Thirty disks from nylon (Valplast) 30 heat-polymerized acrylic material (Paladon 65) were made 10 each immersed in water (control), Val-Clean (peroxide cleanser) Corega Extradent plus microwaving for a period simulating days daily cleansing. parameters measured before after using an interferometric profilometer, meter colorimeter. results statistically analysed by regression, paired-t, Mann-Whitney Kruskal-Wallis tests at α = 0.05 level significance. Results. showed significant differences baseline L* b* between materials (p < 0.01), with significantly lower 0.05) higher roughness Valplas...
