Abstract
The standard method for clinical shade matching is the human eye along with comparative analysis among operators or auxiliary personnel. This study evaluated a new electronic method of clinical shade matching as compared to the standard method that has been almost exclusively used in the past. The Vita Easy Shade system, an electronic method of shade matching, was analyzed for relative accuracy and compared to specific operators' abilities whose effectiveness in color analysis within the realm of dentistry has been determined to be above average by using a simple color screening test. The Vita Easy Shade machine was used on 40 subjects to measure the central region of each patient's tooth #9. Two visual evaluators selected a shade from the same area of tooth #9 for all subjects. Using a 95% score confidence interval, the Vita Easy Shade was predictably accurate between 68% and 91% of the time.
