l presente estudio evalúa los cambios del componente de color Valor denominado como L* en diferentes tipos de resinas de nanorelleno. Se utilizaron las resinas Esthet-X ® (Dentsply), TPH3 ® (Dentsply), Filtek Z-350 ® (3M-ESPE) y Tetric N Ceram ® (Ivoclar-Vivadent) de las cuales se fabricaron 5 discos de resina para cada uno de los tipos con los colores A2, A3 y A3.5 (N=60). Las dimenciones de las muestras son 3mm de grosor y 15 mm de diámetro. Las muestras se fallaron en el espectofotómetro Gretag Macbeth en modo de reflectancia, sobre fondo blanco, bajo la luz D65. Los valores del estudio demuestran que la mayoría de las resinas presentan un valor L* similar y sus diferencias no son estadísticamente significativas.
The present study evaluated changes in the Value of color (L*) in different types of nano-filled composites. Esthet-X, TPH3 (Dentsply), Filtek Z-350 (3M-ESPE) and Tetric N-Ceram (Ivoclar-Vivadent) was used in the study. 5 composites discs were made for each of the types in A2, A3 and A3.5 shades, (N=60). Sample dimensions were 3mm thick and 15 mm in diameter. Samples were measured in the Gretag Macbeth spectrophotometer under D65 light in reflectance mode, against white background. Results showed that most of the composites had a similar L* value and their differences are not statistically significant.
