摘要/Abstract

摘要： 目的　比较Resosolv和氯仿再通塑化后根管的能力。方法　40颗离体牙(80个根管)经FR酚醛树脂塑化后随机分成4组,每组20个根管。A组:K型锉和Resosolv去除根管内塑化物; B组:K型锉和氯仿去除根管内塑化物; C组:超声K型锉和Resosolv去除根管内塑化物; D组:超声K型锉和氯仿去除根管内塑化物。记录根管通畅的个数、操作时间和工作长度丧失情况。结果　Resosolv溶解根管内塑化物的能力明显优于氯仿,Resosolv辅助能通畅87·5%的根管,而氯仿辅助仅能通畅45·0%的根管。结论　Resosolv是有效的根管内塑化物的辅助溶剂。

Abstract:

Objective　To evaluate the possibility for removal of resinifying agent, time required for removal and the working length loss by Resosolv or Chloroform.Methods　40 human teeth (80 root canals) obturated with FR phenolaldehyde agentwere divided into four groups, 20 root canals per group. Group A: Resosolv with K file; group B: chloroform with K file; group C: Resosolv with Ultrasonic K file; group D: Chloroform with ultrasonic K file. Calculating the percentage for removal of resinifying agent, time required for removal and theworking length loss.Results　The effectiveness of Resosolv for removing resinifying agent was better than chloroform. 87.5% of canals could be negotiated by Resosolv; 45% of canals be negotiated by chloroform.Con- clusion　Resosolv is an effective solvent for canals obturated with resinifying agent.
