Resumen
Objetivos: evaluar el efecto de una cerámica interna de alta translucidez de litio disilicio en el mimetismo de un sustrato oscurecido, sin interferir en su capacidad adhesiva. Métodos: se evaluó la fuerza adhesiva del disilicato de litio en el ensayo de microshear después de aplicar la cerámica IPS InLine PoM Opaquer BL1/BL2 (Ivoclar Vivadent, Schaan, Liechtenstein) en una muestra de control, en una muestra con grabado ácido hidrofluórico durante 20 segundos y en una muestra con grabado durante 60 segundos (n=15). La coloración se tomó con un espectrofotómetro digital y se analizó con el método CIEDE2000. Los grupos se dividieron en 4 categorías de grosor de cerámica (n=15). Resultados: el uso de cerámicas internas aumentó la fuerza de adhesión (p<0,005) en comparación con el grupo sin aplicar. En la evaluación del efecto del maquillaje sobre el color final, el análisis de la varianza indicó diferencias estadísticamente significativas entre los grupos (p<0,05). Conclusión: la mascarilla se realizó en todos los espesores y la fuerza adhesiva no se vio afectada.
