Resumen

El objetivo de este estudio fue examinar la decoloración en materiales CAD/CAM utilizados en odontología tras cuatro años de contacto con agua, que constituye el medio al que están más expuestos en la cavidad oral. Se utilizaron tres bloques CAD/CAM de resina de color A2 (Cerasmart, Coltene Brilliant Crios y Shofu Block HC). Se prepararon un total de 180 especímenes, 60 de cada material, con un espesor de 2 mm. Posteriormente, cada material se dividió en tres grupos diferentes según los sistemas de pulido aplicados (Coltene Diatech, Sof-Lex Diamond, Identoflex Diamond Ceramic), siguiendo las recomendaciones de los fabricantes (n=20). La decoloración de los materiales, colocados sobre un fondo blanco y bajo luz natural, se midió al inicio y después de haber sido almacenados en agua destilada durante cuatro años, utilizando el espectrofotómetro VITA Easyshade V. Todos los datos obtenidos se analizaron mediante las pruebas de normalidad de Kolmogorov-Smirnov y Shapiro-Wilk. Tras el proceso de envejecimiento en agua, no se encontraron diferencias estadísticamente significativas entre los grupos de materiales CAD/CAM Cerasmart (p=1.51; p>0.05) y Shofu (p=0.95; p>0.05) al utilizar los tres sistemas de pulido. Se encontró una diferencia estadísticamente significativa entre todos los grupos de sistemas de pulido del material CAD/CAM Coltene (p=0.00). Todos los materiales CAD/CAM mostraron cambios de color superiores al umbral de perceptibilidad ∆E00≤0.8 tras cuatro años de envejecimiento en agua destilada. Los bloques CAD/CAM de Cerasmart (Coltene ∆E00=1.33, Sof-lex ∆E00=1.43, Identoflex ∆E00=1.69) presentaron cambios de color por debajo del umbral de aceptabilidad ∆E00≤1.8 en todos los grupos en los que se aplicaron diferentes sistemas de pulido, mientras que los bloques de Coltene (Coltene ∆E00=3.7, Sof-lex ∆E00=3.81, Identoflex ∆E00=4.69) y Shofu (Coltene ∆E00=2.33, Sof-lex ∆E00=1.74, Identoflex ∆E00=1.91) mostraron cambios de color superiores al valor de aceptabilidad.
