Abstract
ABSTRACTBackground: This study is concerned with color stability and surface roughness of three types of denture basematerials when immersed into three types of denture cleansers.Materials & method: Forty five specimens were prepared, fifteen of each type were immersed into distilled water for48hours which regarded as control and then each five specimens were immersed into one of three different denturecleansers for twelve hours then undergone testing for color stability and surface roughness ,the results were analyzedby paired t-test and ANOVA test.Results: In color stability the hot cure acrylic give non significant difference p>0.05 with denture cleansers, the softbase give (HS) high significant difference which is greatly affected by denture cleansers while the nylon denture wassignificantly affected by bleach rather than the other two cleansers was non significant. The ANOVA test showsmooth effect of fitty dent (NS)on both nylon and soft base. The surface roughness test it was significantly affected bydenture cleansers by t-test while ANOVA the smooth effect of both fitty and lacalut dent on denture bases with nonsignificant difference.Conclusion: Denture cleansers can cause whitening or color fainting or even bleaching. The surface texture affectedby cleansers in deferent level according to time of immersion, concentration and type of active component thatlead to increase of roughness or wear of denture outer surface. The effect of fitty dent was safer in its action andsmoother than bleach and lacalut.Key words: Denture base, dental cleaners, surface roughness. (J Bagh Coll Dentistry 2011;23(3): 17-22).
