咖啡与红茶对2种义齿基托材料的着色及4种义齿清洁剂的洁美效果
The staining effect of coffee and red tea to two kinds of denture base materials and the cleaning efficacy of four kinds of denture cleansers to the stains
摘要
Abstract
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 be-tween coffee and red tea in the two materials was statistically significant (P<0.05);the invisible denture materials are easily colored than heat-curing 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 differ-ence (ΔE) (P < 0.05). Conlusion Compared with the Polident partial, the cleaning efficacy of 1%NaClO、Efferdent and Polident overnight were better.关键词
