Which material provides protection for dentinal regeneration?

• A. Dental Liner
• B. Varnish
• C. Sedative
• D. Dental Bonding

Answer: (A)

Protecting the pulp and supporting dentin healing is best achieved with a bioactive liner. A liner placed on the dentin near the pulp often contains calcium hydroxide, which releases hydroxide ions and creates an alkaline environment. This bioactivity signals odontoblasts to form reparative dentin, leading to a dentin bridge and regeneration of the dentin-pulp complex. Varnish mainly acts as a barrier to reduce leakage but does not promote dentin formation. A sedative soothes the pulp but doesn’t stimulate dentin regeneration. Bonding agents seal and protect but don’t encourage the dentin-pulp tissue to regenerate.
