Resumo: Objective: The purpose of the present study was to evaluate flow, film thickness, working time, setting time, dimensional change, sorption, solubility and cytotoxicity of an experimental epoxy-based root canal sealer with addition of bismuth subnitrate in different concentrations. Methods: Endodontic sealers were prepared with an epoxy resin with bismuth subnitrate additions of 20%, 40%, 60%, 80%, 100% and 120%. Flow, film thickness, working time, setting time, dimensional change, sorption, solubility, and cytotoxicity were studied according to ISO standards. Data were analyzed by one-way ANOVA and Tukey. Results: The flow, working time, water sorption, and solubility significantly decreased with increasing filler particle concentration. The film thickness and dimensional change values significantly increased with higher filler particle addition. There was no difference in the results of setting time and cytotoxicity comparing the groups. Conclusion: Addition of bismuth subnitrate appears to be a promising filler particle for root canal sealer.

Métodos: Os cimentos endodônticos foram preparados a base de resina epóxica com a adição de subnitrato de bismuto nas proporções de 20%, 40%, 60%, 80%, 100% e 120%. Os testes de escoamento, espessura de película, tempo de trabalho, tempo de presa, alteração dimensional, sorção e solubilidade e citotoxicidade foram realizados de acordo com a norma da ISO. Os dados foram analisados com o teste ANOVA de uma via e Tukey. Resultados: Os valores do escoamento, tempo de trabalho, sorção e solubilidade diminuíram significantemente com o aumento da concentração da partícula. A espessura de película e a alteração dimensional aumentaram significantemente com o aumento da adição de partícula. Os resultados de tempo de trabalho e citotoxicidade não apresentaram diferença entre os grupos. Conclusão: A adição de subnitrato de bismuto parece ser uma partícula promissora para ser usada em cimento endodôntico.EDIPUCRS - Editora Universitária da PUCRS2012-11-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/11979Revista Odonto Ciência; Vol. 28 No. 2 (2013); 31-35Revista Odonto Ciência; v. 28 n. 2 (2013); 31-351980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/11979/11854Schwartzer, EduardoCollares, Fabrício MezzomoGenari, BrunaLeitune, Vicente Castelo BrancoNardi, NanceCamassola, MelissaOgliari, FabrícioSamuel, Susana Maria Wernerinfo:eu-repo/semantics/openAccess2014-09-19T18:23:55Zoai:ojs.revistaseletronicas.pucrs.br:article/11979Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2014-09-19T18:23:55Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
