摘要

义齿清洁剂被广泛用于抑制各种念珠菌的定植。目前,添加剂技术在义齿制作中越来越普遍。本研究旨在评估消毒剂对不同义齿基托表面粗糙度和颜色稳定性的影响。圆盘状样品(N=66)暴露于三种不同的消毒剂中:0.5% 次氯酸钠、1% 过氧化氢和 2% 洗必泰。样品分别通过分光光度法和轮廓测定法进行评估。数据分析采用方差分析法(P < 0.05)。在热固化组中,次氯酸钠对表面粗糙度的影响最大(0.2 μm),而洗必泰对表面粗糙度的影响最小(0.001 μm),两者差异显著(p<0.05)。

Effects of various disinfectants on surface roughness and color stability of thermoset and 3D-printed acrylic resin.

Denture cleansers are extensively utilized to inhibit the colonization of various Candida species. Currently, additive technology in denture fabrication has become more prevalent. This study aims to assess the impact of disinfectants on the surface roughness and color stability of distinct denture bases. Disc-shaped samples (N=66) were exposed to three different disinfectants: 0.5% sodium hypochlorite, 1% hydrogen peroxide, and 2% chlorhexidine. The samples underwent evaluation via spectrophotometry and profilometry, respectively. Data analysis was conducted utilizing analysis of variance (ANOVA) (p < 0.05). Within the heat-cured group, sodium hypochlorite resulted in the most notable change in surface roughness (0.2 μm), while chlorhexidine exhibited the least impact (0.001 μm), showing a significant difference (p <0.008). The color change (ΔE) for 3D-printed samples immersed in all disinfectants was higher compared to heat-cured samples. Among the heat-cured samples, chlorhexidine induced the highest ΔE (2.76), while sodium hypochlorite resulted in the lowest (ΔE = 1.44), and this difference was statistically significant (p <0.008). Chlorhexidine caused the most significant color alteration among the solutions, while sodium hypochlorite induced the most considerable changes in surface roughness.
