Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Primary Study Purpose

DIAGNOSTIC

Blinding Strategy

NONE

Neither the patient, the investigator that made the color acquisition or the spectrophotometer had knowledge of tooth color assessed by the other person/method
