Three intermediary base materials, a zinc oxide-eugenol (Cavitec) and two calcium hydroxide liners (Life and Dycal), were selected at random for use as a base beneath amalgam or composite restorations on humans following complete caries removal. Life and Dycal, selected at random, were also used as direct and indirect pulp capping agents as clinically indicated. Clinical evaluations of signs and symptoms were made before treatment and at one-week, six-month, and one-year intervals following treatment. Histological evaluations were performed on three complete caries removal teeth and 18 direct pulp capping teeth six months following treatment. No significant differences in clinical symptomatology resulted between the materials in the complete caries removal group or the indirect and direct pulp capping groups.
在完全去除龋坏组织后，随机选择三种中间基底材料，一种氧化锌丁香酚（Cavitec）和两种氢氧化钙垫底材料（Life和Dycal），用于人类汞合金或复合树脂修复体下方的基底。随机选择的Life和Dycal也根据临床指征用作直接和间接盖髓剂。在治疗前以及治疗后的1周、6个月和1年间隔对体征和症状进行临床评估。在治疗6个月后，对三颗完全去除龋坏组织的牙齿和18颗直接盖髓的牙齿进行组织学评估。在完全去除龋坏组织组或间接和直接盖髓组中，材料之间在临床症状学上没有显著差异。
