Shade-X users might not agree with the shade assignments that Shade-X reports
Shade-X is an accurate and reliable color measurement device. There are times when a user might not agree with the shade assignment that Shade-X reports for a particular tooth. Of course, visual assessment will depend on a number of factors...room lighting, observer's color perception, eye fatigue, tooth hydration or dehydration, and retinal fatigue to name a few. Nonetheless, there are a number of things to consider to ensure accurate results with Shade-X. If the user disagrees with the shade assignment that Shade-X is providing, consider the following:
Do not have the examination light pointing into the mouth during measurement.
Ensure that the calibration plaque is perfectly clean and smear free. Follow instructions found in the Related Support or "Shade-X Users Manual" at the Related Literature link below.
Ensure that the instrument's optics surface is perfectly clean and smear free. Follow instructions found in the "Shade-X Users Manual" at the link below.
Change the disposable tip and re-calibrate.
Ensure that the user is selecting the proper database when viewing the data. There are a number of shade database types...body/dentin, incisal, shade tab, and CAD blocks. A more complete description can be found in the Users Manual or "Shade-X Best Practices" at the link below.
The instrument tip must be flush against the tooth surface. Hold the instrument steady while pressing the measure button. The use of direct vision while measuring will be most helpful in acquiring an accurate shade.
