Use of colorimetry as a diagnostic tool for early detection of peri-implant diseases

At Point B, peri-implant tissues showed lower luminosity (L∗), higher redness (a∗), and reduced b∗ values compared with Point A. Clinically, 48 implants presented peri-implantitis, 9 mucositis, and 6 were considered healthy. Diseased implants demonstrated darker and more reddish peri-implant tissues, revealing a clear correlation between colour alterations and inflammatory status.
