A test was designed for evaluating the distintegration of cementing agents in the oral cavity. The cements were placed in small holes located in the proximal surfaces of cast gold restorations so that the materials were not subject to abrasion. Each cement was placed in one hole located occlusally and one located gingivally. Four commercial cements of four different types (zinc phosphate, zinc silicophosphate, polycarboxylate, and EBA-Alumina zinc oxide/eugenol) were tested in 15 patients, and differences were observed in the deterioration rates of the different cements over the 6 month period. The disintegration rate of a given cement was the same in the gingival and occlusal positions. No correlation was observed between the clinical data on loss of material and the solubility of the cements as measured by conventional in vitro tests.
设计了一项测试，用于评估口腔中粘结剂的崩解情况。将粘结剂置于铸造金修复体邻面的小孔中，以使材料不受磨损。每种粘结剂分别置于一个咬合面的孔和一个龈面的孔中。对15名患者测试了四种不同类型的四种市售粘结剂（磷酸锌、硅磷酸锌、聚羧酸锌和EBA - 氧化铝氧化锌/丁香酚），并观察到不同粘结剂在6个月期间的劣化率存在差异。给定粘结剂在龈面和咬合面位置的崩解率相同。通过传统体外测试测得的材料损失临床数据与粘结剂的溶解度之间未观察到相关性。
