粘合剂体系中的功能单体可以通过增强润湿和脱矿作用以及通过与钙的化学键合来改善粘合。本研究验证了功能单体化学结构的微小变化可能改善其键合有效性的假设。评价了化学结构略有不同的三种实验膦酸酯单体（HAEPA、EAEPA和MAEPA）和10-MDP（对照）。粘合剂的性能是确定的4个水泥，不同的功能单体的微拉伸粘结强度。基于粘附-脱钙概念，通过原子吸收分光光度法测定功能单体的钙盐的溶解速率来评估化学键合电位。粘合剂水泥的高粘合强度对应于相应官能单体的钙盐的低溶解速率。后者是根据粘附-脱钙概念，暗示高化学结合能力。我们得出结论，粘合剂材料的粘合性能取决于功能单体的化学结构。
Functional monomers in adhesive systems can improve bonding by enhancing wetting and demineralization, and by chemical bonding to calcium. This study tested the hypothesis that small changes in the chemical structure of functional monomers may improve their bonding effectiveness. Three experimental phosphonate monomers (HAEPA, EAEPA, and MAEPA), with slightly different chemical structures, and 10-MDP (control) were evaluated. Adhesive performance was determined in terms of microtensile bond strength of 4 cements that differed only for the functional monomer. Based on the Adhesion-Decalcification concept, the chemical bonding potential was assessed by atomic absorption spectrophotometry of the dissolution rate of the calcium salt of the functional monomers. High bond strength of the adhesive cement corresponded to low dissolution rate of the calcium salt of the respective functional monomer. The latter is according to the Adhesion-Decalcification concept, suggestive of a high chemical bonding capacity. We conclude that the adhesive performance of an adhesive material depends on the chemical structure of the functional monomer.
