Although spectrophotometry objectively quantifies tooth color, variation across ICDAS categories and its relationship with lesion severity remain unclear. The present in\u00a0vitro study therefore characterized spectrophotometric measurements across ICDAS categories, evaluated their association with severity, and quantified differences across categories.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>Three hundred unrestored extracted posterior teeth were classified as ICDAS 0\u20134 by a calibrated examiner.
