摘要

目的:该研究旨在评估和比较饮料、义齿清洁剂和葡萄糖酸氯己定溶液对柔性义齿基托材料表面粗糙度的影响:制作 50 个直径为 50±1 毫米、厚度为 0.5±0.05 毫米的柔性义齿基托树脂试样。试样分为五组,每组十个试样。试样分别浸泡在蒸馏水(对照组 A)、热咖啡(对照组 B)、冷饮(对照组 C)、含过硼酸钠的义齿清洁剂(对照组 D)和 2% 葡萄糖酸氯己定溶液(对照组 E)中。试样每天在上述溶液中浸泡 10 分钟,持续 60 天。在第 1 天、第 20 天和第 60 天,用原子力显微镜评估表面粗糙度(Ra)。统计分析采用双向方差分析和 Tukey 后检验:结果:双向方差分析显示,Ra 平均值随浸泡所用溶液类型的不同而有显著差异(p 结论:浸泡在酸性冷饮中,Ra 平均值会发生显著变化:将热塑性聚酰胺柔性义齿基底树脂试样浸泡在酸性冷饮和含过氧化物的义齿清洁剂中,会使其表面更加粗糙。

Effect of beverages, denture cleanser and chlorhexidine gluconate on surface roughness of flexible denture base material: an in vitro study.

Purpose: The purpose of the study was to evaluate and compare the effect of beverages, denture cleanser and chlorhexidine gluconate solution on surface roughness of flexible denture base material.

Materials and methods: Fifty flexible denture base resin specimens measuring 50±1mm in diameter and 0.5±0.05 mm in thickness were fabricated. The specimens were divided into five groups each containing ten specimens. The specimens were immersed in distilled water (Control group A); hot coffee (Group B); cold beverage (Group C); sodium perborate containing denture cleanser (Group D) and 2% chlorhexidine gluconate solution (Group E). The specimens were immersed for 10 min daily in mentioned solutions for up to 60 days. Surface roughness (Ra) was evaluated on the 1st, 20th and 60th day with the help of atomic force microscope. The statistical analysis was done using two-way ANOVA and Tukey's Post hoc test.

Results: The two- way ANOVA revealed that the average Ra values varied significantly depending on the type of solution used for immersion (p<0.001) and the duration of immersion (p<0.001). Variation in surface roughness with cold beverage was highest (p=0.001). On the 60th day the surface roughness of flexible denture base resin material was higher with cold beverage (0.184 μm) and denture cleanser (0.203 μm) than that of distilled water (0.052 μm) hot coffee (0.030 μm) and 2% chlorhexidine gluconate (0.068 μm).

Conclusion: Exposure to cold beverage, which was acidic in nature and peroxide containing denture cleanser, produces much rougher surface in the thermoplastic polyamide flexible denture base resin specimens.
