Introduction: The objetive and reproducible measurement of dental colour, is a problem in Dentistry. Dental colorimeters, which have recently appeared in the market, can be helpful in this context. Objetive: We attempt to evaluate the reliability of three dental colorimeters in colour measurements. Material and Method: We measured dental colour in each of the twelve anterior teeth from ten patients, three times per tooth with each of the dental colorimeters and we registered five times the colour of each of the sixteen artificial teeth from three shade guides (Vitapan Classical). Results: Reliability in measuring shade guides colour ranged from 72.25 to 93.7%, depending on which colorimeter was used, while in patients it varied from 81.94 to 95%. Conclusions: The Easyshade colorimeter showed the highest degree of reliability in general and for each shade from the different guides, both in vivo and in vitro.
