Comparison of warm gutta-percha condensation techniques in ribbon shaped canal: weight of filled gutta-percha

Abstract

The purpose of this study is to evaluate the two warm gutta-percha filling techniques by measuring the weight changes of resin blocks before and after canal filling in ribbon shaped canal. Simulated ribbon shaped root canals in 30 transparent resin blocks were instrumented to #40 using .06 taper Profile. 15 resin blocks were obturated with gutta-percha using cold lateral condensation. Warm lateral condensation using the Endotec II was then accomplished on the same 15 blocks. Another 15 resin blocks were obturated using the System B. All canals were obturated without sealer. The resin blocks were weighed after canal preparation and after each subsequent obturation, and then weight changes of the resin blocks were calculated.The results were as follows. 1. Warm lateral condensation using Endotec II and continuous wave of condensation using System B produced a denser obturation of gutta-percha compared with conventional cold lateral condensation (p<0.01). 2. There was no significant difference between warm lateral condensation and continuous wave condensation. In conclusion, the warm gutta-percha condensation techniques like warm lateral condensation and continuous wave condensation can be expected to bring favorable canal obturation results in ribbon shaped canals. . 적절한 충전 을 위해서는 근관벽에 잘 적합된 치밀한 근관 충전이 필요 하며 core material의 부피가 최대화 되어야하고 sealer의 부피는 최소화되어야 한다 3) . 근관충전을 위해서 많은 방법들이 사용되어지고 있는데 측방가압법은 가장 널리 쓰이는 방법으로 근관내로의 gut- 리본형태의 근관에서의 열연화 근관 충전법의

“…The results showed that the continuous wave of condensation technique produced a filling with greater density than conventional cold lateral compaction in vitro. In addition, Kim et al (2002) compared warm gutta-percha filling techniques with conventional cold lateral condensation using simulated C-shaped root canals embedded in resin blocks. They concluded that warm gutta-percha condensation techniques can be expected to result in favourable canal filling in C-shaped root canals.…”
