Clinical and Radiographic Diagnosis of Underlying Dark Shadow From Dentin (ICDAS 4) in Permanent Molars

Caries Res. 2013;47(5):429-32. doi: 10.1159/000350924. Epub 2013 May 25.

Abstract

This study investigated the radiographic pattern of underlying dark shadow from dentin (ICDAS 4) in permanent molars and assessed the association between enamel breakdown and radiographic features. Ninety-five teeth (54 patients) were clinically and radiographically assessed. The majority of ICDAS 4 caries lesions presented enamel breakdown (n = 78, 82.1%) and no radiographic image (n = 64, 67.4%) or a radiolucent zone restricted to the enamel-dentin junction (n = 17, 17.9%). No association was found between enamel breakdown and radiographic features. This study suggests that a radiographic examination is needed prior to the decision making process for underlying dark shadows from dentin.
