Dental cements with syringate esters such as 2-ethylhexyl syringate with or without vanillate esters dissolved in o-ethoxybenzoic acid as ingredients of the liquid when mixed with metal oxide powder yield rapid setting, insoluble cements that have high strength, do not inhibit free radical polymerization, adhere strongly to metal, and reduce carries. Use of silanized glass filler to the powder in conjunction with the addition of monomer to the liquid gives an even stronger cement.
含有2-乙基己基丁香酸酯的牙科水泥,以及在o-乙氧基苯甲酸中溶解的香草酸酯,当与金属氧化物粉末混合时,产生快速固化、不溶性、强度高、不抑制自由基聚合、强烈附着于金属并减少龋齿的牙科水泥。在粉末中加入硅烷化玻璃填料,并向液体中添加单体,可以使水泥更加坚固。
