The document summarizes the International Caries Detection and Assessment System (ICDAS). ICDAS provides a standardized system for detecting and coding dental caries, accounting for both enamel and dentine lesions. It has applications in dental education, clinical practice, research, and epidemiology/public health. ICDAS involves visual inspection of clean, dried teeth and codes lesions from 0 to 6 based on their severity. It also provides codes for caries detection associated with restorations and sealants, as well as root surface caries detection.
