• How does children experience caries diagnosing performed with DIAGNOcam compared to X-rays? INVESTIGATION VARIABLES: Caries data are recorded according to the standardized diagnostic method at surface level (dental sites with approximal contacts). Each examined tooth surface is assessed as either 1) intact; 2) caries only in enamel; 3) caries i dentin; or 4) the surface cannot be judged. The same classification is used for X-rays and DIAGNOcam.
