OBJETIVO: Evaluar y comparar la resistencia flexural de las resinas fluida convencional, fluida bulk fill y fluida de alta carga. MATERIALES Y MÉTODOS: Se confeccionaron treinta especímenes de 2mm x 2mm x 25mm de las resinas fluidas Tetric N-Flow (TNF), Filtek Bulk Fill Flowable Restorative (FBF) y Beautifil Flow Plus F00 (BFP); se distribuyeron en tres grupos de acuerdo con la marca (n=10) y fueron almacenadas por 24 horas a 37◦C en agua destilada. Según la regulación ISO 4049, se llevó a cabo la evaluación de flexión de 3 puntos en un aparato de ensayos universales con 0,5 mm/min de velocidad hasta que se fracture. Se analizaron los resultados mediante pruebas de ANOVA y Tukey. P<0.05. RESULTADOS: Se registraron disparidades estadísticamente significativas entre los grupos, valor de p=0.011. Los grupos que mostraron discrepancias estadísticamente significativas fueron los gr...

Objective: To evaluate and compare the flexural strength of conventional flowable, bulk fill flowable and highly filled flowable resins. Materials and methods: Thirty 2mm x 2mm x 25mm specimens of Tetric N-Flow (TNF), Filtek Bulk Fill Flowable Restorative (FBF) and Beautifil Flow Plus F00 (BFP) flowable resins were made up; they were distributed into three groups according to brand (n=10) and stored in distilled water for 24 hours at 37ºC. The 3-point bending test according to ISO 4049 was performed on a universal testing machine at a speed of 0.5 mm/min until fracture. The results were evaluated with Anova and Tukey tests. P<0.05. Results: Statistically significant differences were found between the groups with a value of p=0.011. According to the statistical analysis, the groups that showed statistically significant differences were the BFP and TNF groups (p=0.015) and the BFP and ...
