Leal SC, et al. - A sum of 74 pediatric dentists were included in this study to estimate the treatment decision-making process, after caries detection [using CAST instrument (Caries Assessment Spectrum and Treatment)], for enamel (CAST 3) and non-cavitated dentin caries lesions (CAST 4) before and after interpreting radiographic images. A significant association of the requirement for radiographs with the presence and depth of the caries lesion was recorded. They preferred to monitor CAST 3 lesions before and after the radiographic evaluation. They observed that treatments indicated before and after radiographic analysis were sealant (33%) and restoration (40%) for CAST 4 lesions limited to the outer half of dentin. They suggested the treatment of enamel lesions via less invasive treatments. Particularly for the lesions involved the inner half of dentin, they found the impact of radiographs on the decision.
