ABSTRACT
Abstract The aim of this study was to evaluate the physicochemical properties, cytocompatibility and antibiofilm activity of a new calcium silicate-based endodontic sealer, Sealer Plus BC (MK Life, Brazil), in comparison with TotalFill BC Sealer (FKG Dentaire SA, Switzerland) and AH Plus (Dentsply, Germany). Setting time and flow were evaluated based on ISO 6876 standard. The pH was evaluated after different periods, and radiopacity by radiographic analysis (mmAl). Solubility (% mass loss) and volumetric change (by micro-CT) were assessed after 30 days of immersion in distilled water. Cytocompatibility was assessed by methyltetrazolium (MTT) and neutral red (NR) assays, after exposure of Saos-2 cells to the sealer extract for 24 h. An additional analysis was performed by using MTT assay after 1, 3 and 7 days of exposure of Saos-2 to the sealers 18 dilution extracts. Antibiofilm activity against Enterococcus faecalis and/or Candida albicans was evaluated by crystal violet assay and modified direct contact test. The physicochemical properties were analyzed using ANOVA/Tukey tests; MTT and NR data were analyzed by ANOVA and Bonferroni tests; the antimicrobial tests were analyzed by Kruskal-Wallis and Dunn tests (α=0.05). Sealer Plus BC had proper setting time, radiopacity, flow and alkalization capacity. Sealer Plus BC was significantly more soluble than AH Plus (p<0.05) and presented volumetric change similar to AH Plus and TotalFill BC (p>0.05). Sealer Plus BC presented antibiofilm activity and no cytotoxic effect. In conclusion, although Sealer Plus BC had higher solubility, this sealer showed proper physicochemical properties, cytocompatibility, and antibiofilm activity.
RESUMO
Resumo O objetivo deste estudo foi avaliar as propriedades físico-químicas, a citocompatibilidade e a atividade antibiofilme de um novo cimento endodôntico à base de silicato de cálcio, Sealer Plus BC (MK Life, Brasil), em comparação com TotalFill BC Sealer (FKG Dentaire SA, Suíça) e AH Plus (Dentsply, Alemanha). O tempo de presa e o escoamento foram avaliados com base nas normas ISO 6876. O pH foi avaliado após diferentes períodos, e a radiopacidade por análise radiográfica (mmAl). A solubilidade (% de perda de massa) e alteração volumétrica (por micro-CT) foram avaliadas após 30 dias de imersão em água destilada. Citocompatibilidade foi avaliada pelos ensaios metiltetrazólio (MTT) e vermelho neutro (NR), após exposição das células Saos-2 ao extrato de cimento por 24 horas. Análise adicional foi realizada através do ensaio MTT após 1, 3 e 7 dias de exposição das células Saos-2 aos extratos dos cimentos na diluição de 18. Atividade antibiofilme contra Enterococcus faecalis e/ou Candida albicans foi avaliada pelos ensaios cristal violeta e contato direto modificado. As propriedades físico-químicas foram analisadas utilizando os testes ANOVA e Tukey; MTT e NR foram analisados pelos testes ANOVA e Bonferroni; os ensaios antimicrobianos foram analisados pelos testes Kruskal-Wallis e Dunn (α=0.05). Sealer Plus BC apresentou tempo de presa, radiopacidade e escoamento adequados, além de capacidade de alcalinização. Sealer Plus BC foi significantemente mais solúvel que AH Plus (p<0.05) e apresentou alteração volumétrica similar à de AH Plus e TotalFill BC (p>0.05). Sealer Plus BC apresentou atividade antibiofilme, sem efeito citotóxico. Como conclusão, embora Sealer Plus BC apresente maior solubilidade, este cimento apresentou propriedades físico-químicas adequadas, citocompatibilidade e atividade antibiofilme.
