ABSTRACT Diagnosis of occlusal enamel caries in archaeologically derived collections remains a controversial problem because the accumulation contaminants fissures can interfere with diagnosis. Certain novel light‐induced fluorescence methods, such as DIAGNODent pen 2190 (DD) and VistaCam iX Proof (VC), have been used to detect dental clinical settings. In this study, abilities DD VC initial material is determined compared those other methods (visual inspection, X‐ray, histology, micro‐CT)....
