ABSTRACT
Abstract The aim was to evaluate in vitro cytotoxicity and genotoxicity of Bio-C Repair (BCR), compared to Endosequence BC Root Repair (ERRM), MTA Angelus (MTA-Ang), and MTA Repair HP (MTA-HP). MC3T3 osteoblastic cells were exposed to extracts of the repairing bioceramic cements. After 1, 3, and 7 days, cytotoxicity and genotoxicity were evaluated by MTT and Micronucleus tests, respectively. Cells not exposed to biomaterials were used as a negative control. Data were compared using ANOVA two-way, followed by the Tukey Test (α=5%). MTA-Ang and MTA-HP showed no difference in relation to control regarding cytotoxicity in any experimental times. BCR and ERRM reduced cell viability after 3 and 7 days (p<0.05); however, the reduction caused by BCR was less than that caused by ERRM. Considering the micronucleus formation, all biomaterials caused an increase after 3 and 7 days (p<0.05), being greater for the BCR and ERRM groups. It can be concluded that BCR is non-cytotoxic in osteoblastic cells, as well as MTA-Ang e MTA Repair HP. BCR and ERRM showed greater genotoxicity than others tested biomaterials.
RESUMO
Resumo O objetivo foi avaliar in vitro a citotoxicidade e genotoxicidade do Bio-C Repair (BCR), em comparação com o Endosequence BC Root Repair (ERRM), MTA Angelus (MTA-Ang) e MTA Repair HP (MTA-HP). As células osteoblásticas MC3T3 foram expostas aos extratos dos cimentos biocerâmicos reparadores. Após 1, 3 e 7 dias, a citotoxicidade e a genotoxicidade foram avaliadas pelos testes MTT e Micronúcleo, respectivamente. Células não expostas aos biomateriais foram utilizadas como controle negativo. Os dados foram comparados por ANOVA de dois fatores, seguido do Teste de Tukey (p = 5 %). MTA-Ang e MTA-HP não apresentaram diferença em relação ao controle quanto à citotoxicidade em nenhum dos tempos experimentais. BCR e ERRM reduziram a viabilidade celular após 3 e 7 dias (p < 0,05); no entanto, a redução causada pelo BCR foi menor que aquela causada pelo ERRM. Todos os biomateriais causaram aumento na formação de micronúcleos após 3 e 7 dias (p < 0,05), sendo maior para os grupos BCR e ERRM. O BCR não é citotóxico em células osteoblásticas, assim como cimentos MTA-Ang e MTA Repair HP. BCR e ERRM apresentaram maior genotoxicidade do que outros biomateriais testados.
