Resumen

Objetivo: En este estudio se evaluó la resistencia a la fractura de premolares maxilares tratados endodónticamente restaurados con diferentes materiales restauradores. Métodos: Sesenta premolares maxilares fueron sometidos a la misma preparación de cavidad mesio-oclusal-distal, tratamiento endodóntico y divididos en 5 grupos (n = 10): Grupo Coltosol - GCO restaurado con material de silicato de calcio; Grupo de cemento de ionómero de vidrio - GCIV, restaurado con Maxxion R; Cemento de ionómero de vidrio modificado - GCIM, restaurado con Gold Label 2; Grupo compuesto - GC, restaurado con Z100, y el grupo de control positivo (GP) - dejado sin restaurar. Un grupo permaneció intacto (n = 10) sirviendo como control negativo (GN). Las muestras se sometieron a pruebas de resistencia a la fractura mediante la máquina de prueba universal hasta que se produjo la fractura y se registró en newtons (N). El patrón de fractura se evaluó y describió como favorable o desfavorable. Los resultados se analizaron estadísticamente mediante un análisis de varianza de 1 vía y la prueba de Tukey post hoc con una diferencia estadística significativa a P <0,05. Resultados: Se encontraron mayores resultados de resistencia a la fractura para GC (1.128,35 ± 249,17), GCIM (1.250,77 ± 173,29) y GN (1.277,22 ± 433,44) (p <0,05). Se observaron fracturas más favorables en el GCO (6), GC (7) y GN (7) (p <0,05). Conclusión: Los dientes restaurados con composite y CIV modificado presentaron la misma resistencia que los dientes intactos. Los dientes restaurados con Coltosol y GIC presentaron una resistencia similar a los dientes no restaurados.
