Aim: This study aimed to evaluate the dental students' performance in ICDAS (International Caries Detection and Assessment System) coding with different levels of clinical experience.
Materials And Methods: Dental students ( = 122) in their clinical years, year 3 ( = 37), year 4 ( = 44), and year 5 ( = 41) received training (two-hour introductory lecture on ICDAS, followed by a 90 min e-learning video, and practice sessions using extracted teeth and photographs) from a calibrated expert. After training, the students examined a prevalidated set of extracted teeth and assigned scores in two sessions.
