What term describes a tooth decay lesion visible on a tooth?

• A. Cavity
• B. Carious lesion
• C. Fissure
• D. Abfraction

Answer: (B)

Understanding how decay shows up on a tooth helps here. When the damage from dental caries is visible on a tooth, we describe it as a carious lesion—the lesion denotes the area affected by the decay process itself. This term precisely flags that the defect is due to caries, regardless of whether there’s a small spot or a larger hollow. A cavity refers more to the hollow space that can form as decay progresses, which is related but not the same as naming the lesion. Fissures are natural grooves that may trap decay but aren’t decay lesions themselves, and abfraction describes a stress-related wear defect, not caries. So the best term for a tooth decay lesion visible on a tooth is carious lesion.
