Abstract(s)
Objetivo: Avaliar o efeito do eucaliptol, no tempo de desobturação de dentes obturados
com GuttaCore® e na percentagem de área de gutta-percha residual.
Métodos: 30 dentes monoradiculares com canais retos, instrumentados com o sistema
ProTaper Gold® até à lima F3, obturados com GuttaCore®, divididos em três grupos de
10, desobturados com sistema ProTaper Retreatment® e lima F3: grupo I –sem utilização
de eucaliptol; grupo II - utilização de eucaliptol, antes do início da desobturação; grupo
III - utilização de eucaliptol também entre limas. Para cada grupo, foi registado o tempo
de trabalho das limas dentro do canal, o tempo total de retratamento e a percentagem de
área de gutta-percha residual, utilizando radiografias e o programa informático
SketchAndCalcTM. A análise estatística foi realizada utilizando os testes nãoparamétricos: teste de Kruskal-Wallis e teste de Mann-Whitney U.
Resultados: O grupo III obteve o menor tempo de trabalho das limas, com diferença
significativa para os outros dois grupos. O grupo I obteve o menor valor de tempo de
retratamento com diferença significativa para os outros dois grupos. O grupo I foi o que
obteve menor valor de percentagem de área residual de gutta-percha, com diferença
significativa com o grupo II, que obteve o valor maior.
Conclusões: O eucaliptol tem efeito solvente no sistema GuttaCore®, diminuindo o
tempo de trabalho das limas, no entanto aumenta o tempo total de retratamento e pode
aumentar a área residual de gutta-percha, se não for utilizado ao longo do retratamento.
Aim: To evaluate the effect of eucalyptol, on the time to remove GuttaCore filling from teeth and on the percentage area of residual gutta-percha. Methods: 30 straight single-root teeth, instrumented with ProTaper Gold® system up to the F3file, oburated with GuttaCore®, divided into three groups of 10 teeth, removed material filling with ProTaper Retreatment® system and with the F3 file: group I - without use of eucalyptol; group II - use of eucalyptol, before the beginning of the desobturation; group III - use of eucalyptol also between files. For each group was recorded, the files working time within the canal , total retreatment time and percentage area of residual gutta-percha, by the use of radiographs and SketchAndCalcTM software. The statistical analysis was performed with non-parametric tests: Kruskal-Wallis test and Mann-Whitney U test. Results: Group III had the shortest working time for files, with a significant difference for the other two groups. Group I had the lowest retreatment time value with a significant difference for the other two groups. Group I was the one that obtained the lowest percentage area of residual gutta-percha, with a significant difference with group II, which obtained the highest value. Conclusions: Eucalyptol has a solvent effect in the GuttaCore® system, reducing the working time of files, however it increases the total retreatment time and can increase the residual area of gutta-percha if not used during retreatment.
