BACKGROUND: The aim of this in vivo study was to compare
spectrophotometric backgrounds - white (WB) with
cuspal (C), black (BB) with non cuspal (NC) - in order to
determine if the oral natural conditions could be used as reliable
backgrounds instead of the traditional black and/or white
for in vivo color matching.
Methods: Spectrophotometric measurements were performed
on ninety-three upper right permanent central incisor.
Among inclusion criteria were A1, A2, A3 (Vita Classical

Background: Shade matching is a significant treatment step and a challenge for the clinical team with potentially high costs for color correction. Currently, in the United States, the majority of private dental practitioners use visual color matching, but a recent study has reported a high rate of mistakes of subjective color determination among graduate dentists. Objective: The aim of this retrospective study is to analyze whether a change in the oral background due to dental occlusion can influence tooth color determination.
