The aim of this study was to determine whether the use of a topical surfactant (Hydrosystem), designed for clinical use, improved the quality of the impression surface of two poly(vinyl siloxane) materials used in vivo. Before impressions were taken, Hydrosystem was applied to the maxillary left or right premolar teeth, allocated at random, in 50 subjects. The untreated side acted as a control for each subject. The impressions were examined for quality of reproduction and number of surface defects. Hydrosystem was found to significantly improve the quality of reproduction.
本研究的目的是确定一种专为临床使用设计的局部表面活性剂（Hydrosystem）是否能改善两种体内使用的聚（乙烯基硅氧烷）材料印模表面的质量。在取印模前，将Hydrosystem随机应用于50名受试者的上颌左侧或右侧前磨牙。未处理的一侧作为每个受试者的对照。检查印模的复制质量和表面缺陷数量。结果发现，Hydrosystem能显著提高复制质量。
