Photo-analysis software for matching resin composite shades in dentistry

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study compares a novel photo-analysis software, digital spectrophotometer readings, and traditional visual shade matching to determine how well they agree on resin composite shade selection. Custom shade tabs and standardized photography under daylight with a gray reference card are used to balance images and reduce color bias. Participants are adults with sound maxillary incisors, and measurements are taken with controlled lighting and standardized patient posture to minimize confounding factors. The study uses a fixed workflow where photos are processed by software before comparing results to the visual method and spectrophotometer measurements.
