The optimum concentration and application time for an experimental dentin primer composed of an aqueous solution of 1,6-hexanediol were determined by measuring the wall-to-wall polymerization contraction gap width of a commercial light-activated resin composite in a cylindrical dentin cavity prepared in an extracted human molar. Contraction gap formation was completely prevented only when the dentin cavity wall was primed with 45 wt% 1,6-hexanediol for 60 s. There were no significant differences in tensile bond strength among primers composed of 20.0-57.5 wt% 1,6-hexanediol. These results suggest that the optimum concentration and application time are 45 wt% and 60 s, respectively.
通过测量在拔除的人磨牙制备的圆柱形牙本质洞中，一种市售光固化树脂复合材料的壁对壁聚合收缩间隙宽度，来确定由1,6 -己二醇水溶液组成的实验性牙本质底漆的最佳浓度和应用时间。仅当用45 wt%的1,6 -己二醇对牙本质洞壁进行60秒的底漆处理时，收缩间隙的形成才被完全阻止。由20.0 - 57.5 wt%的1,6 -己二醇组成的底漆之间的拉伸粘结强度没有显著差异。这些结果表明，最佳浓度和应用时间分别为45 wt%和60秒。
