对桉油醇和d-柠檬烯作为氯仿替代溶剂的能力进行了评价。测量了在72个用树脂固定和填充的模拟根管中软化和移除牙胶所需的时间。在用#60根管钉预备根管根尖后，使用四种不同的充填技术。用每种溶剂软化这些填充物，然后移除，首先使用#15 Hedstrom锉插入整个工作长度，然后用#60铰刀移除剩余的填充物。对两种器械的放置进行了定时：一种是Hedstrom钉插入根尖，另一种是铰刀取出充填材料。无论是不同的溶剂还是填充技术，都不会对H型修复体到达根尖所需的时间产生明显的影响。然而，铰刀去除填充材料的时间受填充技术和所使用的溶剂的影响。
Eucalyptol and d-limonene were evaluated for their ability to serve as a substitute solvent for chloroform. The amount of time required to soften and remove the gutta-percha in 72 instrumented and filled simulated root canals in epoxy blocks was measured. After preparation to the apices of the block canals with a #60 file, four different filling techniques were used. These obturations were softened with each solvent and then removed, first using a #15 Hedstrom file inserted to full working length, and then removing the remaining filling mass with a #60 reamer. The two instrument placements were timed: one for the Hedstrom file insertion to the apex and the other for the reamer to remove the filling material. Neither the different solvents nor the filling techniques had a significant effect on the times required for the H-files to reach the apex. However, the times for the reamer to remove the filling materials were effected both by the filling techniques and the solvents used.
