Summary

The aim of this study is to evaluate the influence of several factors (light, extrinsic stain removal and operator's experience) in tooth color assessment. Tooth color will be assessed by two different operators with visual shade guides under standardized light conditions and using a light correcting device (Smile Lite) or with a dental spectrophotometer in human subjects. Color measurement will be made before and 1 week after dental prophylaxis.
