A root canal model was used to test the relative efficiency of various commonly used endodontic solvents including eucalyptol, eucalyptus oil, orange oil, chloroform, and xylene to dissolve or soften gutta-percha and several different types of sealers (Proco-Sol, AH26, and Sealapex). There was no significant difference in the ability of the solvents to dissolve gutta-percha and the zinc oxide-eugenol-based sealer Proco-Sol. The resin-based sealer, AH26, was only dissolved in chloroform and took considerable time (> 30 min). The calcium hydroxide-based sealer, Sealapex, could not be tested because it was found not to set at all unless in contact with air. All of the solvents for both Proco-Sol and gutta-percha produced clinically acceptable dissolving times.
使用根管模型测试了各种常用牙髓溶剂的相对效率,这些溶剂包括桉叶油、桉叶油、橙油、氯仿和二甲苯,以溶解或软化牙胶和几种不同类型的封闭剂(Proco-Sol、AH26和Sealapex)。溶剂溶解牙胶和氧化锌丁香酚基封闭剂Proco-Sol的能力没有显著差异。树脂基封闭剂AH26仅溶于氯仿,且需要相当长的时间(>30分钟)。氢氧化钙基封闭剂Sealapex无法进行测试,因为发现它除非与空气接触否则根本不会凝固。用于Proco-Sol和牙胶的所有溶剂都产生了临床上可接受的溶解时间。
