The key idea is that early signs of decay risk in infants show up on radiographs as dark, radiolucent areas where the tooth structure has begun to demineralize. The most telling radiographic indicators are subtle radiolucent lesions in the pits and fissures of erupted teeth and early interproximal radiolucencies between adjacent teeth. These sites are the first to harbor cariogenic plaque in young children, because pits and fissures trap plaque and are difficult to clean, and interproximal surfaces are where decay can progress unseen between contacts. When such early radiolucencies are visible, they point to a heightened risk of rapid caries development in the neonate or infant.

In contrast, radiographic signs like increased bone height or radiopaque enamel do not reflect early caries activity, and fractures describe trauma rather than initial decay risk.
