Para-Post dowels were cemented by using combinations of cement, cleansing agents, and dentinal treatments. The comparative retentive strengths were as follows: 1. Para-Post posts cemented with composite into mechanically corrugated post spaces recorded the greatest retention. 2. The retention of the posts cemented with composite into post spaces rinsed with 1 ml of 17% EDTA with a pH of 7.5 and followed immediately by 1 ml of 5.25% NaOCl was lowest. 3. The retention of the posts secured with zinc phosphate into mechanically corrugated post spaces was significantly higher than with untapped post spaces. 4. The retentive strength of the posts placed with glass-ionomer cement into post spaces, irrigated with 1 ml of 40% polyacrylic acid solution, and rinsed with distilled water was comparable to that of posts secured with zinc phosphate cement without roughened post spaces.
副桩通过使用粘结剂、清洁剂和牙本质处理剂的组合进行粘结。比较的固位强度如下：1. 用复合树脂粘结到机械波纹状桩道中的Para-Post桩记录到最大的固位力。2. 用复合树脂粘结到用1毫升pH值为7.5的17%乙二胺四乙酸（EDTA）冲洗且随后立即用1毫升5.25%次氯酸钠冲洗的桩道中的桩的固位力最低。3. 用磷酸锌粘结到机械波纹状桩道中的桩的固位力显著高于未开髓的桩道。4. 用玻璃离子水门汀放置到用1毫升40%聚丙烯酸溶液冲洗并用蒸馏水冲洗的桩道中的桩的固位强度与用磷酸锌水门汀粘结且桩道未粗糙化的桩的固位强度相当。
