Abstract

Denture plaque control for the prevention of aspiration pneumonia is very important. The pellicle is the major cause of denture plaque adhesion. Few basic studies have evaluated the effectiveness of denture cleansers for pellicles composed of salivary proteins. The adhesion of salivary proteins formed on denture base metal and the removal rate were quantitatively analyzed using the QCM method after denture cleanser injection. This is the first study to compare the cleaning effects of denture cleanser on denture base metal using the QCM method. Au and Ti sensors were employed as the denture base metals. Albumin was used for the adsorption of salivary proteins. The results showed that no significant difference was found between Au and Ti in the amounts of albumin adsorbed, and the rate of albumin removal from Ti was significantly higher than that of Au. In this study, the cleaning effectiveness of denture cleanser was confirmed based on the adsorbed amount and the removal rate of salivary proteins adsorbed onto denture base metals. Thus, the QCM method was suggested to be a useful tool for removing the effects of salivary proteins from denture cleaning agents on denture base metal.

用石英晶体微天平法清洗义齿清洁剂对义齿基托金属的影响分析

控制牙菌斑对预防吸入性肺炎非常重要。薄膜是造成义齿斑块粘连的主要原因。很少有基础研究评估义齿清洁剂对唾液蛋白膜的有效性。应用QCM方法定量分析了义齿清洁剂注射后唾液蛋白在义齿基托金属上的粘附情况和去除率。这是首次使用QCM方法比较义齿清洁剂对义齿基底金属的清洁效果。使用Au和Ti传感器作为义齿基底金属。白蛋白用于唾液蛋白的吸附。结果表明，Au和Ti的白蛋白吸附量没有显著差异，Ti的白蛋白去除率明显高于Au。本研究通过吸附在义齿基底金属上的唾液蛋白的吸附量和去除率来证实义齿清洁剂的清洁效果。因此，QCM方法被认为是一种有用的工具，可以消除义齿清洁剂中唾液蛋白对义齿基底金属的影响。
