dc.description.abstractObjective: To compare in vitro microhardness of resin Tetric® N - Ceram Bulk Fill and SonicFill™ resin as curing depth. Materials and methods: The studio was experimental in vitro. 32 specimens were divided into 4 groups performed: Tetric® N-Ceram Bulk Fill to 2mm thick, Tetric® N-Ceram Bulk Fill to 4mm thick, SonicFill ™ to 2mm thick and SonicFill ™ to 4mm thick. Were prepared in a 6x2x4mm metal matrix thickness, which were irradiated from the top surface. All specimens were stored in a stove at 37 ° C for 24 hours before initial measurement. The Vickers hardness was measured according to the depth of the test bodies from the top and bottom surfaces of the resin block of the four groups mentioned above. Data were analyzed with Shapiro Wilk and Student's t test. Results: The SonicFill ™ resin at 2 and 4 mm in depth was increased microhardness average 74.75 + 3.38 kg/mm2 and 72.65 + 1.93 kg/mm2 respectively compared to the Tetric® N-Ceram Bulk Fill resin. Furthermore microhardness Tetric® N-Ceram Bulk Fill, SonicFill™ and the upper surface is greater with an average of 60.87 + 2.53 kg/mm2 and 74.75 + 3.38 kg/mm2 in the lower surface with a mean of 51.25 + 1.95 kg/mm2 and 71.37 + 2.68 kg/mm2. Conclusions: Statistically significant differences were found Tetric® N-Ceram Bulk Fill and SonicFill ™ at 2 and 4mm depth, giving greater surface microhardness in SonicFill ™ to 2mm and 4mm depth at the top surface.
dc.description.abstractObjetivo: comparar in vitro la microdureza superficial de la resina Tetric® N-Ceram Bulk Fill y la resina SonicFill™, según profundidad de fotocurado. Materiales y métodos: el estudio fue experimental in vitro. Se realizaron 32 cuerpos de prueba divididos en 4 grupos: Tetric® N-Ceram Bulk Fill a 2mm de espesor, Tetric® N-Ceram Bulk Fill a 4mm de espesor, SonicFill™ a 2mm de espesor, SonicFill™ a 4mm de espesor. Se prepararon en matrices metálicas de 6x2x4 mm de espesor, los cuales fueron irradiados desde la superficie más superficial. Todos los especímenes se almacenaron en una estufa a 37◦C durante 24 horas, antes de la medición. La dureza Vickers se midió en función al espesor del material por la superficie superior e inferior del cuerpo de prueba, de los cuatro grupos antes mencionados. Los datos se analizaron con las pruebas de Shapiro Wilk y t de Student. Resultados: la resina SonicFill™ a los 2 y 4mm de espesor tuvo mayor microdureza superficial con una media de74.75+3.38kg/mm2 y 72.65+1.93kg/mm2 respectivamente a comparación de la resina Tetric® N-Ceram Bulk Fill. Por otro lado la microdureza superficial de la resina Tetric® N-Ceram Bulk Fill y SonicFill™en la superficie superior es mayor con una media de 60.87+2.53kg/mm2 y 74.75+3.38kg/mm2 que en la superficie inferior con una media de 51.25+1.95kg/mm2 y 71.37+2.68 kg/mm2. Conclusiones: se encontraron diferencias estadísticamente significativas al comparar las resinas Tetric® N-Ceram Bulk Fill y SonicFill™ a los 2mm y 4mm de profundidad, con mayor microdureza superficial en la resina SonicFill™a los 2mm y 4mm de profundidad en la superficie superior.
