Brief Summary

Twenty patients of Dental Medicine School will be recruited to participate in a pilot study about dental color measurement in which visual and digital instruments will be tested. Informed consents and local ethical committee clearance will be previously obtained. All data will be collected after an oral hygiene procedure. Two different methods of color measurement will be tested: visual method with VITA Classical (VC) and VITA 3D-Master (VM) and digital method with Spectroshade Micro (SS) and VITA Easyshade (ES). The CIE L\*a\*b\* values will be evaluated in the VC scale for both methods. Reproducibility will be assessed based on intra-operator intra-device agreement and the accuracy will be assessed based on inter-device agreement using the kappa coefficient (K) and intraclass correlation coefficient (ICC), respectively. Results will be presented as mean, with 95% CI
