Objective Measurement of Tooth Color Using Spectrophotometry and ICDAS: Quantifying CIELAB Color Changes Across Caries Severity

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The International Caries Detection and Assessment System (ICDAS) is widely used for early caries detection but relies on visual interpretation. Although spectrophotometry objectively quantifies tooth color, variation across ICDAS categories and its relationship with lesion severity remain unclear. The present in vitro study therefore
