Flexural strength and elastic module of high, medium and low density resins
Aim: To determine the flexural strength and elastic modulus of high, medium and low density composite resins. Material and methods: 88 specimens of 25mmx2mmx2mm were divided into 11 groups of 8 according to the resin. Group 1: Filtek Z350 XT, group 2: Rok, group 3: Filtek P60, group 4: Filtek Z250 X...

Aim: To determine the flexural strength and elastic modulus of high, medium and low density composite resins. Material and methods: 88 specimens of 25mmx2mmx2mm were divided into 11 groups of 8 according to the resin. Group 1: Filtek Z350 XT, group 2: Rok, group 3: Filtek P60, group 4: Filtek Z250 XT, group 5: Polofil Supra, group 6: Te-Econom Plus, Group 7: Grandio, Group 8: Brilliant New Line, Group 9: Prisma AP.H, group 10: Wave Flow and Group 11: Brilliant Flow. Four samples were preserved for 24 hours and four for 30 days. An universal test machine was used with a head speed of 1mm per minute by applying a three points load until fracture. Kruskal Wallis test was applied. Results: Flexural strength 24 hours (MPa): higher values Filtek Z250 XT (112, 25 +/-4.52), Filtek P60 (110, 75 +/-6.43) and Grandio (109, 98 +/-9, 12) and lower Brilliant Flow (49, 00 +/-2.27). 30 days: higher values Grandio (124, 35 +/-14.78), Filtek P60 (119, 98 +/-11.60) and lower Rok (59, 50 +/-4.94) with significant differences (p<0,05). Elastic module 24 hours (GPa): Higher values Grandio (8.33 +/-0.46), Filtek Z250 XT (6.96 +/-0.51), Filtek P60 (6.46 +/-0.29) and lower Brilliant Flow (1.52 +/-0.16). 30 days: higher value Grandio (10.51 +/-0.47) and lower Wave Flow (2.17 +/-0.13) with significant differences (p<0,05). The time influenced significantly increasing values for both tests (p<0,05). Conclusion: Composite resins showed different behaviors. Time factor influenced increasing values excepting Rok and Filtek Z250 XT which kept its approximately equal values. Objetivo: determinar la resistencia a la flexión y el módulo elástico de resinas compuestas de alta, mediana y baja densidad. Material y Métodos: 88 especímenes de 25mmx2mmx2mm se dividieron en 11 grupos de 8 según la resina. Grupo 1: Filtek Z350 XT, grupo 2: Rok, grupo 3: Filtek P60, grupo 4: Filtek Z250 XT, grupo 5: Polofil Supra, grupo 6: Te-Econom Plus, grupo 7: Grandio, grupo 8: Brilliant New Line, grupo 9: Prisma AP.H, grupo 10: Wave Flow y grupo 11: Brilliant Flow. Cuatro muestras fueron conservadas por 24 horas y cuatro por 30 días. Se empleó una máquina de ensayo universal con una velocidad de cabezal de 1mm por minuto aplicando una carga de tres puntos hasta la fractura. Se aplicó la prueba de Kruskal Wallis. Resultados: Resistencia a la flexión 24 horas (MPa): valores mayores Filtek Z250 XT (112,25+/-4,52), Filtek P60 (110,75+/-6,43), y Grandio (109,98+/-9,12) y más bajo Brilliant Flow (49,00+/-2,27). 30 días: valores más altos Grandio (124,35+/-14,78), Filtek P60 (119,98+/-11,60) y más bajo Rok (59,50+/-4,94) con diferencias significativas (p<0,05). Módulo Elástico 24 horas (GPa): valores mayores Grandio (8,33+/-0,46), Filtek Z250 XT (6,96+/-0,51), Filtek P60 (6,46+/-0,29) y más bajo Brilliant Flow (1,52+/-0,16). 30 días: valor más alto Grandio (10,51+/-0,47) y más bajo Wave Flow (2,17+/-0,13) con diferencias significativas (p<0,05). El factor tiempo influyó significativamente aumentando los valores en ambos ensayos (p<0,05). Conclusión: las resinas compuestas mostraron comportamientos disímiles. El factor tiempo influyó aumentando los valores a excepción de Rok y Filtek Z250 XT que mantuvieron sus valores aproximadamente iguales.
