The purpose of this in vitro study was to determine the effects of differing salivary contamination periods on the surface topography of etched enamel surfaces using SEM techniques. The results indicated that salivary contamination of etched enamel for 1 second or longer resulted in the formation of surface coatings that could not be removed by a water wash. It was concluded that should salivary contamination of an etched enamel surface occur, it would be necessary to repeat the etching procedure to ensure adequate bonding of a resin material.
本体外研究的目的是使用扫描电子显微镜（SEM）技术确定不同唾液污染时间对酸蚀釉质表面形貌的影响。结果表明，酸蚀釉质表面被唾液污染1秒或更长时间会导致形成水洗无法去除的表面涂层。得出的结论是，如果酸蚀釉质表面发生唾液污染，有必要重复酸蚀过程以确保树脂材料的充分粘结。
