Abstract

Spectrophotometers are used in dental practice in order to determine colour changes of dental composites as accurate as possible. The aim of this study is to find out if the VITA Easyshade dental spectrophotometer and the laboratory UNICAM 4 UV-VIS spectrophotometer have similar efficiency in measuring the colour of dental composites regardless of their inorganic filling. The results indicate that dental spectrophotometers have difficulties in detecting colour changes of dental nanocomposites..
