Four different shades were used to produce 20 samples of resin-based composite and 20 samples of porcelain to evaluate the performance ability of an intra oral test spectrophotometer compared to a reference spectrophotometer. The absolute colour coordinates CIELAB values measured with both spectrophotometers were significantly different (p<0.001). However, a high correlation was found (p<0.001) despite the low concordance noticed. The colour difference Delta E* values calculated between different shades also were significantly different between both spectrophotometers (p<0.05). Therefore, the Easy Shade can be used in dental practice and dental research with some limitations.
