Introduction: ICDAS (the International Caries Detection and Assessment System) is a new approach for coding and recording the six stages of caries severity, varying from initial changes visible in enamel to frank cavitation in dentine. Objectives: To assess and compare the inter-examiner accuracy of the International Caries Detection and Assessment System (ICDAS) among dental faculty members and undergraduates after ICDAS training for dental caries detection. Materials and Methods: Twenty permanent human teeth, without sealants or restorations and with a range of ICDAS codes between 0 and 6, were selected from a pool of extracted teeth and cleaned. Digital images of selected surfaces were taken using the Shofu Camera. Three dental faculty members examined the teeth and the details of each code were discussed based on a published paper concerning ICDAS until a consensus was reached and thereafter the reference set was developed and validated by the international expert of ICDAS before initiating the training session. ICDAS training using E-learning program, extracted teeth exercise and photograph discussion was given to dental faculty members of different specializations and dental undergraduates. After the training the participants were requested to code the carious lesion using ICDAS on the selected extracted teeth. Thereafter, these codes were compared with the reference set coding, Kappa (weighted: Wkappa) statistics and Yates corrected Chi Square were used using SPSS 17.0. Results: For detection of caries the calibration indicated an inter-rater Wkappa ranging from 0.67-0.85 among dental faculty members and 0.57-0.75 among dental undergraduates. There was no significant difference in between the performances of dental faculty members and dental undergraduates using ICDAS for dental caries detection (p>0.05). Conclusion: The ICDAS can be learned and practiced by dentist of any specialization and dental undergraduates. However, it could be suggested that more time prac¬ticing and training could help the study participants in developing their skills in the caries detection process.
