Abstract

Este estudo ex vivo avaliou a eficácia de diferentes protocolos de irrigação final na remoção da smear layer e na erosão da dentina intrarradicular.Trinta e cinco caninos humanos extraídos foram ins- trumentados e divididos aleatoriamente, de acordo com as técnicas de irrigação final utilizadas, em 7 grupos: 1 (ED3M) e 3 (ED3US), EDTA a 17% por 3 minutos com agitação manual e ultrassônica, respectivamente; 2 (CA30M) e 4 (CA30US), ácido cítrico a 10% por 30 segundos com agitação manual e ultrassônica, respectiva- mente; 5 (CA3M) e 6 (CA3US), ácido cítrico a 10% por 3 minutos com agitação manual e ultrassônica, respectivamente; e 7 (Na3), NaOCl a 5,25% por 3 minutos sem agitação (controle). Todas as amostras foram irrigadas com NaOCl a 5,25%, divididas longitudi- nalmente e examinadas em microscopia eletrônica de varredura (MEV) nos terços apical, médio e coronal. Os dados foram analisa- dos pelos testes de Kruskal-Wallis e Mann-Whitney. A eficácia do EDTA 17% e do ácido cítrico 10% na remoção da smear layer foi significativamente maior que NaOCl 5,25% (controle). Não houve diferenças significativas entre os protocolos finais de irrigação na remoção da smear layer ou nos efeitos erosivos. Entretanto, ao comparar os terços dos grupos 1 (ED3M) e 2 (CA30M), a menor remoção da camada de smear layer e erosão foram observadas no terço apical, mas o procedimento do grupo 4 (CA30US) foi mais eficaz que 1 (ED3M) (p = 0,0004), 2 (CA30M) (p = 0,0018) ou 3(ED3US) (p = 0,0003) na remoção da smear layer no terço apical.Concluiu-se que os protocolos utilizados neste estudo foram se- melhantes na remoção da smear layer e efeitos erosivos.
