Abstract

The dental spectrophotometers are good in identifying natural tooth colour in oral cavities but they have problems when encountering composite materials. In this pilot study we intend to evaluate the capability of the Easyshade Advance dental spectrophotometer to measure colour variations of the dental composite materials which have been introduced in solutions with food dyes. The values obtained by the Easyshade spectrophotometer revealed significant statistical results for the CIE L*a*b parameters measured within our study. The capacity of the instrument to measure the colour of dental materials in in vitro experiments and the various groups of food pigments represent further subjects of study..
