Which statement best describes selective caries removal in deep lesions?

• A. Remove infected dentin while leaving affected near pulp to preserve vitality.
• B. Remove only enamel.
• C. Remove all caries including near pulp.
• D. Do not remove caries.

Answer: (A)

Selective caries removal in deep lesions focuses on preserving pulp vitality by removing only the soft, infected dentin and leaving the harder, demineralized dentin near the pulp (the affected dentin) intact. This approach reduces the bacterial load without risking pulp exposure, and when the tooth is properly sealed with a durable restoration, the remaining affected dentin can remineralize or become reinforced, helping to arrest progression. Removing all caries, especially near the pulp, increases the risk of pulp exposure and may not provide added benefit in comparison, while removing only enamel misses the dentin involvement. Not removing caries at all would allow continued decay and potential pulpal damage.
