First clinical sign of dental caries?
Show answer and explanation
Correct answer: A. White spot lesion
- A. Correct. The white spot lesion (chalky, opaque area of enamel) represents the earliest clinically visible sign of demineralization/incipient caries.
- B. Cavitation represents a later, more advanced stage of caries progression, not the first sign.
- C. A brown spot lesion typically represents a more chronic/arrested lesion, occurring after the white spot stage.
- D. Pulp exposure represents a very advanced stage of caries, far beyond the initial clinical sign.
