ClinConnect Summary

This clinical trial is studying a new way to match the color of dental restorations, like crowns or veneers, to natural teeth. Traditionally, dentists use a visual method where they compare a tooth to a color chart, but this can lead to mistakes due to differences in lighting and individual perception of color. This study aims to see if using digital photography and special software can provide a more accurate and consistent way to determine the right shade for dental work, compared to the usual visual and instrumental methods.

To participate in this trial, you need to be between 20 and 50 years old and able to give consent. You should have teeth that require full coverage restorations due to issues like discoloration or damage, but you should not have any active dental diseases or poor oral hygiene. Participants can expect to have their tooth color matched using the new digital method, and their results will be compared to the traditional techniques. This research could lead to better outcomes for patients needing dental restorations by ensuring a more precise color match.
