Estudio colorimétrico de diferentes sistemas de blanqueamiento y su efecto sobre los tejidos dentales

Abstract

La elevada demanda de tratamientos estéticos en la práctica diaria tiene como consecuencia un aumento en la realización de tratamientos de blanqueamiento, lo que detemina la necesidad de estudios para conocer el efecto sobre el color y poder determinar pautas terapeúticas más efectivas y adecuadas para cada caso con el menor riesgo para los tejidos dentales. Con la realización de esta investigación perseguimos diferentes objetivos. Por un lado, evaluar el color conseguido con el empleo de perborato de sodio en el blanqueamiento de dientes desvitalizados, utilizando para ello métodos objetivos para poder determinar la variación dentro del espacio de color CIELab, y las alteraciones ultraestructurales, estudiándolas mediante MEB. El siguiente objetivo es valorar la combinación de dos protocolos de blanqueamiento, interno y combinado externo e interno para valorar si el uso de un blanqueamiento combinado supone o no una mejoría en los resultados de color y su repercusión en los tejidos duros dentales. Por último estudiamos la influencia de la aplicación de un proceso de triturado del agente blanqueante, perborato de sodio, que permitiría la obtención de partículas con granulometrías progresivamente inferiores en función del tiempo de molido, y su repercusión en la variación de color para los parámetros a*, b*, L* y ΔΕ.
