The effects of powder erichment and subambiant mixing temperatures on the film thickness of three zinc phosphate cements were measured by two methods. A decrease in film thickness accompanied reduced mixing temperatures and standard powder-liquid ratios. Increased powder-liquid ratios with reduced mixing temperatures showed a decreased film thickness when measured according to ADA Material Specification No. 8. Both Fleck's and S. S. White cement showed an increased film thickness when measured by a tapered-die system. Because of the geometry of the preparations, small increases in cement film thickness can be clinically significant when cementing complete veneer crowns.
通过两种方法测量了粉末富集和低于环境温度的混合温度对三种磷酸锌水门汀膜厚度的影响。膜厚度的减小伴随着混合温度和标准粉液比的降低。当按照ADA材料规范第8号进行测量时，粉液比增加且混合温度降低显示膜厚度减小。当通过锥形模系统测量时，弗莱克水门汀和SS怀特水门汀的膜厚度均增加。由于修复体的几何形状，在粘结全冠时，水门汀膜厚度的小幅增加在临床上可能具有重要意义。
