Which caries type is usually detected earlier clinically than radiographically?

• A. Beginning occlusal caries
• B. Occlusal caries
• C. Proximal caries
• D. Recurrent caries

Answer: (A)

Early pit-and-fissure (occlusal) caries are usually found first by visual-tactile examination. At the beginning stage, the lesion is confined to the outer enamel in the pits and fissures, often presenting as a chalky white area or a rough, softened spot that you can feel with a probe. Radiographs, on the other hand, are not very sensitive to these initial enamel changes on occlusal surfaces because enamel is dense and the lesion hasn’t created a radiolucent area yet. Only when the decay progresses deeper, typically into dentin, does a radiograph show a change. So the earliest detection tends to be clinical rather than radiographic for beginning occlusal caries.
