摘要

用于固定修复体的牙胶合剂需要一些性能。其中之一是材料的酸性特性，因为(OH)-离子在凝固阶段释放可能对纸浆产生不良影响。在本研究中，测试了三种不同的粘结剂在固化反应中的PH值，发现所使用的粘结剂会引起PH值的变化。胶结物的酸度随时间变化很大，确定了三种胶结物的PH值在24小时内下降。

[PH changes of different cements].

Some properties are required in dental cements used in fixed restorations. One of them is the acidic characteristic of the material since (OH)- ions released during the setting phase may have undesirable effects on the pulp. In this study three different luting cements were tested regarding to their PH values during setting reaction and was found that cements used caused PH changes. Acidity of cements had changed considerably depending upon time and it was determined that PH values of three cements decreased in the period of 24 hours.
