Abstract

The aim of this study was to assess the role of a polarizing filter upon the accuracy of shade matching, when digital photography, with a system specifically designed for dentistry was used. CIE L*a*b* color parameters obtained from digital images, taken in two different conditions were compared with the parameters recorded with spectrophotometer Vita EasyShade Advanced 4.0 considered as standard. All the values for ΔE2000 parameter calculated between spectrophotometry and digital photography (with direct and polarized light) were over the acceptability threshold value (ΔE>1.87). The use of digital photography and polarizing filters can be considered as alternatives to the current methods for shade matching..
