Abstract
Softening time of gutta-percha cones was studied in vitro using five chemical solvents: xylol, chloroform, turpentine, eucalyptol, and orange oil. An apparatus which reproduces the penetration force of an endodontic file was used on the sectioned roots of previously filled teeth. The most rapid chemical solvent of gutta-percha cones was chloroform and the slowest was eucalyptol.
摘要
使用五种化学溶剂（二甲苯、氯仿、松节油、桉叶油和橙油）在体外研究牙胶尖的软化时间。在先前已充填牙齿的离体牙根上，使用一种能再现根管锉穿透力的装置。牙胶尖最快速的化学溶剂是氯仿，最慢的是桉叶油。
