What step has the purpose of protecting the pulp and promote recovery when indicated?

• A. Finishing
• B. Isolation
• C. Pulp protection
• D. Caries removal

Answer: (C)

Pulp protection is the step that shields the pulp from irritation and supports healing when the preparation is deep or close to the pulp. By placing a liner or base between dentin and the final restoration, this protective layer reduces chemical, thermal, and microleakage irritants reaching the pulp. It also helps stimulate reparative dentin formation, which promotes recovery and preserves vitality. Finishing simply shapes the final restoration, isolation keeps the field dry during procedures, and caries removal removes decay; none of these specifically provide the targeted pulp protection and healing support that a pulp-protective liner or base offers.
