ABSTRACT
Abstract The aim of this study was to evaluate in vitro the cytotoxicity on human periodontal ligament fibroblasts of three root-end filling materials MTA Angelus(r), EndoSequence Root Repair Material Putty(r) and Super EBA(r). A primary culture of human periodontal ligament fibroblasts was previously obtained in order to evaluate the cytotoxicity of the three extracts from the root-end filling materials after 2 and 7 days of setting. Serial dilutions of these extracts (11, 12, 14 and 18) were evaluated at 1, 3 and 7 days using the methyl-thiazol-tetrazolium (MTT) colorimetric assay. Cell viability was evaluated as percentage of the negative control group, which represented 100% cell viability. Statistical analyses were done with t-test, ANOVA and Kruskal-Wallis test at a significance level of 5%. It was found that the main difference among root-end filling materials was in the higher dilutions (p<0.05), but there was a similar behavior in lower dilutions (p>0.05). Cell viability of MTA Angelus(r) was superior for 2-day setting (p<0.05), compared with the other two root-end fillings. There were no statistically significant differences between 7-day set MTA Angelus(r) and EndoSequence Root Repair Material Putty(r). Super EBA(r) showed the lowest percentage of cell viability at higher dilutions (p<0.05). Therefore, MTA Angelus(r) and EndoSequence Root Repair Material Putty(r) were less cytotoxic in the highest dilution (11) compared with Super EBA(r).
RESUMO
Resumo O objetivo deste trabalho foi avaliar in vitro a citotoxicidade em fibroblastos do ligamento periodontal humano de três cimentos de retrobturação MTA Angelus(r), EndoSequence Root Repair Material Putty(r) e Super EBA(r). Uma cultura de fibroblastos primários do ligamento periodontal humano foi obtida anteriormente a fim de avaliar a citotoxicidade dos três extratos dos cimentos de retrobturação após 2 e 7 dias de endurecimento. As diluições em série destes extratos (11, 12, 14 e 18) foram avaliados em 1, 3 e 7 dias empregando o ensaio colorimétrico metil-tiazol-tetrazólio (MTT). A viabilidade celular foi calculada em base da porcentagem do grupo de controle negativo, que representou 100% de viabilidade de células. As análises estatísticas foram realizadas com o teste t, ANOVA e teste de Kruskal-Wallis a um nível de significância de 5%. Verificou-se que a principal diferença entre os cimentos de retrobturação estava nas diluições mais elevadas (p<0,05) e houve um comportamento semelhante nas diluições mais baixas (p>0,05). A viabilidade celular dos fibroblastos do ligamento periodontal humano foi superior para MTA Angelus(r) de 2 dias de endurecimento (p<0,05), em comparação com os outros materiais de retrobturação. Não houve diferença significante entre MTA Angelus(r) e EndoSequence Root Repair Material Putty(r) de 7 dias de endurecimento. Super EBA(r) mostrou a menor percentagem da viabilidade celular nas diluições mais altas (p<0,05). Portanto, os cimentos de retrobturação MTA Angelus(r) e EndoSequence Root Repair Material Putty(r) foram menos citotóxicos na diluição mais alta (11) em comparação com Super EBA(r).
