Beginning occlusal caries are best detected by which method?

• A. Bitewing radiographs
• B. Panoramic radiographs
• C. Electric pulp testing
• D. Clinical examination

Answer: (D)

Early occlusal caries are best detected through clinical examination because the initial changes occur right at the enamel surface in pits and fissures and can be seen or felt before any radiographic signs develop. A careful visual inspection with good lighting and moisture control can reveal color changes, opacity, or chalky areas in the grooves. Gentle tactile probing can also uncover softness or stickiness where demineralization has begun. Radiographs lag behind in this stage, since they only show caries once the lesion has penetrated enamel enough to create a radiolucency in dentin. Panoramic radiographs have lower sensitivity for small occlusal lesions, and electric pulp testing doesn’t assess caries at all. So, the best method for detecting beginning occlusal caries is a thorough clinical examination.
