Resumo: Purpose: The purpose of this study was to evaluate the flexural strength and modulus of two adhesive systems using biaxial flexural strength test. Methods: The bonding agents (Pentron Clinical Technologies) tested were: Bond 1 (B1) and NanoBond (NB). Thirteen disks (6.1 mm diameter and 0.6 mm thick) were prepared with adhesive solutions of each bonding agents using Teflon molds. The adhesive solutions within the molds were light-activated with XL 3000 curing unit (3M ESPE) for 10 s on both sides. The disks were stored for 10 days and were tested in a universal testing machine (1.27 mm/min – Instron 5844). Data were statistically analyzed by one-way ANOVA (α=0.05). Results: The mean values of fracture strength (±SD) for adhesive systems were (in MPa): B1- 89.7±7.6 e NB- 131.1±9.5. Modulus means (±SD) were (in MPa): B1- 1999.9±258.4 e NB- 2314.5±271.0. Conclusion: The filled adhesive system (NB) exhibited higher strength and flexural modulus means than the unfilled adhesive B1. Key words: Dentin-bonding agents; flexural strength; flexural modulus

Metodologia: Os adesivos (Pentron Clinical Technologies) estudados foram: Bond 1 (B1) e NanoBond (NB). Treze discos de cada adesivo foram preparados com dimensões aproximadas de 6,1 mm de diâmetro e 0,6 mm de espessura. Os discos de adesivos foram confeccionados utilizando-se moldes de teflon e fotopolimerizados com aparelho XL 3000 (3M ESPE). Após armazenamento por 10 dias, os discos foram testados em máquina universal de ensaio (Instron 5844), com velocidade de 1,27 mm/min. Os dados foram submetidos à análise de variância (1 fator) ao nível de significância de 0,05. Resultados: Os valores médios (±DP) de resistência flexural para os adesivos foram (em MPa): B1- 89,7±7,6 e NB- 131,1±9,5. Os valores médios de módulo flexural (±DP) foram (em MPa): B1- 1999,9±258,4 e NB- 2314,5±271,0. Conclusão: O adesivo contendo partículas de carga (NB) mostrou maiores valores de resistência flexural e módulo de flexão que o adesivo B1.
