ABSTRACT
This study evaluated the effectiveness of 3 solvents (Citrol orange oil, Eucalyptol and Tetrachloroethylene) and 2 associations of solvents (Citrol orange oil+Tetrachloroethylene and Eucalyptol+Tetrachloroethylene) on 3 types of gutta-percha (conventional, thermoplastic and EndoREZ) and Resilon. Ten discs (10 mm diameter x 1 mm thick) from each material were prepared using standard metallic molds. Each specimen was weighed to determinate its initial mass. The specimens were immersed in the solvents for 10 min, followed by immersion in distilled water for 20 min, and were then reweighed to obtain the final mass. The mean weight loss determined the solvent capacity. Data were analyzed by ANOVA and Tukey's test at 5 percent significance level. Tetrachloroethylene was the most effective on conventional gutta-percha (p<0.05). Tetrachloroethylene was also the most effective on thermoplastic gutta-percha, but it was not significantly different (p>0.05) from Eucalyptol+Tetrachloroethylene, Citrol+Tetrachloroethylene, and Citrol. All solvents and associations presented little effectiveness on Resilon. The association Eucalyptol+Tetrachloroethylene was the most effective on EndoREZ, but it did not differ significantly (p>0.05) from Citrol+Tetrachloroethylene and Tetrachloroethylene. All evaluated substances presented solvent action. Tetrachloroethylene improved the effectiveness of both Citrol and Eucalyptol.
RESUMO
Este estudo avaliou a efetividade de 3 solventes (Citrol, Eucaliptol e Tetracloroetileno) e 2 associações (Citrol+Tetracloroetileno e Eucaliptol+Tetracloroetileno) sobre 3 tipos de guta-percha (convencional, termoplástica e EndoREZ) e Resilon. Dez discos (10 mm x 1 mm) de cada material foram preparados utilizando moldes metálicos. Cada espécime foi pesado para determinar a massa inicial. Os mesmos foram imersos nas soluções testadas por 10 min e em água destilada por 20 min. Os espécimes foram novamente pesados, agora para determinar a massa final. A perda média de peso determinou a capacidade solvente. Os dados foram analisados pelos testes ANOVA e Tukey. O tetracloroetileno foi o mais efetivo sobre a guta-percha convencional (p<0,05). Ele também foi o mais efetivo sobre a guta-percha termoplástica, mas sem diferença significativa para o Eucaliptol+Tetracloroetileno, Citrol+Tetracloroetileno e o Citrol (p>0,05). Todos os solventes e associações apresentaram pequena ação sobre o Resilon. A associação Eucaliptol+Tetracloroetileno obteve o melhor resultado sobre o EndoREZ, mas sem diferença significativa para o Citrol+Tetracloroetileno e o Tetracloroetileno (p>0,05). Todas as soluções apresentam ação solvente. O Tetracloroetileno melhorou a efetividade do Citrol e do Eucaliptol.
