Which outcome is noted as greater in sealed teeth in relation to dentin formation?

• A. Less dentin bridging
• B. More dentin bridging
• C. No change in dentin formation
• D. Increased dentin degradation

Answer: (B)

Keeping the pulp environment sealed after a restoration or exposure protects the pulp from irritants and bacteria, allowing its cells to respond by laying down reparative dentin. This dentin bridge forms as a natural barrier at the site of dentin exposure, helping to seal the pulp and preserve vitality. Because the sealed environment reduces ongoing irritation and supports odontoblast activity, more dentin bridging is observed. In contrast, options suggesting less bridging, no change, or more degradation don’t fit the idea that sealing promotes a protective reparative response by the pulp.
