Icdas II criteria (international caries detection and assessment system).

The International Caries Detection and Assessment System (ICDAS) is a clinical scoring system which allows detection and assessment of caries activity. ICDAS was developed for use in clinical research, clinical practice and for epidemiological purposes. A recent review of caries detection criteria systems found that there were inconsistencies among the research criteria for caries measuring systems. There is a need to an uniform system which allows comparison of data collected in different researches. ICDAS allows detection of caries process at every stage and characterization of the caries activity status of lesion. Later, the criteria were modified and ICDAS II created. The aim of this review is to inform about the ICDAS II and make a comparison between ICDAS II criteria and other caries detection systems.
