Objetivos: O objetivo do presente trabalho foi comparar a eficácia de diferentes soluções de irrigante – Hipoclorito de sódio 3%, Ácido etilenodiaminatetraacético 17% e Ácido cítrico 10% - na remoção de pó hidróxido de cálcio misturado com gel de clorhexidina 2%, previamente aplicado em dois sulcos longitudinais realizados no canal radicular.
Materiais e Métodos: Foram selecionados 45 dentes humanos monocanalares, moldados em cubos de silicone de forma a criar uma base; seguidamente, foram instrumentados com limas Pro-Taper® até F3 e divididos longitudinalmente, com o uso de um micrótomo. Realizaram-se, então, dois sulcos, que foram preenchidos com a medicação intracanalar. Os dentes foram divididos aleatoriamente em 3 grupos (n=15) e a medicação intracanalar previamente aplicada foi removida usando diferentes soluções de irrigante: Hipoclorito de sódio 3%, Ácido etilenodiaminatetraacético 17% e Ácido cítrico 10%. A irrigação ultrassónica foi utilizada como técnica de agitação do irrigante para todos os grupos experimentais e todos os sulcos foram fotografados, após aplicação da medicação intracanalar e após a remoção da mesma.
Resultados: As solução de Ácido cítrico 10% foi superior às soluções de Hipoclorito de sódio 3% e Ácido etilenodiaminatetraacético 17% na remoção da medicação intracanalar (P<0,05). Não houve diferenças significativas entre os outros grupos (P>0,05). Em todos os dentes do grupo experimental do Hipoclorito de sódio 3% observou-se um precipitado laranja-acastanhado, mas em nenhum dos outros grupos.
Conclusão: A solução de Ácido cítrico 10% demonstrou maior eficácia do que Hipoclorito de sódio 3% e do que Ácido etilenodiaminatetraacético 17%. O precipitado laranja-acastanhado foi apenas encontrado no grupo irrigado com Hipoclorito de sódio 3%.
Introduction: The objective of the present study was to compare the efficacy of different irrigant solutions - sodium hypochlorite 3%, ethylenediaminetetraacetic acid 17% and citric acid 10% - in removal of calcium hydroxide powder mixed with 2% chlorhexidine gel, previously applied in two longitudinal grooves made in the root canal. Materials and Methods: 45 monocanal human teeth were selected, molded in silicone cubes in order to create a base; after, they were instrumented with Pro-Taper® files till F3 and divided lengthwise with the use of a microtome. Two grooves were, then, made which were filled with intracanal medication. The teeth were randomly divided into 3 groups (n = 15) and the intracanal medication previously applied was removed using different irrigant solutions: sodium hypochlorite 3%, ethylenediaminetetraacetic acid 17% and citric acid 10%. Ultrasonic irrigation was used as the irrigant solution stirrer technique for all experimental groups and all furrows were photographed after intracanal dressing application and after its removal. Results: The 10% citric acid solution was superior to 3% sodium hypochlorite and 17% ethylenediaminetetraacetic acid in the removal of intracanal dressing (P <0.05). There were no significant differences between the other groups (P> 0.05). An orange-brown precipitate was observed in all teeth of the 3% sodium hypochlorite experimental group but in none of the other groups. Conclusions: The 10% citric acid solution demonstrated greater efficacy than 3% sodium hypochlorite and 17% ethylenediaminetetraacetic acid. The orange-brown precipitate was only found in the group irrigated with 3% sodium hypochlorite.
