Hypothesis
How much can clinicians trust device-selected tooth shades without visual verification?
Conclusion
Carestream showed the highest reliability in shade matching, while Medit had the lowest.
Supporting Evidence
- Carestream achieved the highest clinical pass rate at 78.2%.
- Easyshade had a clinical pass rate of 63.5%.
- Primescan and Trios had pass rates near or below 50%.
- Medit demonstrated the lowest performance with a pass rate of 31.3%.
- Statistical analysis showed significant differences in device performance.
Takeaway
This study looked at how well different devices can match tooth colors, and found that some are much better than others.
Methodology
Participants' tooth colors were measured using four intraoral scanners and a spectrophotometer, comparing results to a visual observer's selections.
Limitations
Only one expert observer was used, and the devices tested were not the latest models.
Participant Demographics
Participants were male and female, all under the age of 35, with natural, unrestored teeth.
