Abstract

The difference between visual and instrumental analyses of a shade selection on natural teeth was investigated. With visual analysis, five prosthodontist examined the middle third of the unrestored maxillary right central incisor of a patient using VITAPEN® classical and Vita Toothguide 3D-MASTERsr tooth shade guide. In instrumental analysis, one prosthodontist examined the same teeth using a spectrophotometer (Shadepilot™, Degudent, Hanau-Wolfgang, Germany, software 2.40). Overall, instrumental analysis is more accurate and reproducible than a visual assessment. However, the difference is clinically acceptable.
