Abstract - The purpose of this study was to assess the reliabilty of a digital image analysis system and to assess its suitability for quantifying the colour (including whiteness) of extracted teeth in a purpose built artiï¬cial oral cavity after a whitening regime. Extracted teeth were treated with a scale and polish and a bleaching solution. The Image analysis system showed excellent intra operator repeatability. Signiï¬cant tooth colour and whiteness changes occurred after the bleaching treatment. The digital image system has been shown to be a reliable and valid method for assessing colour and whiteness changes on extracted teeth after whitening treatments.
KEY WORDS: Image analysis; Tooth colour; extracted teeth
