What purpose does the use of liners serve in dental procedures?

The use of liners in dental procedures primarily serves as a dentin stimulator. Liners are often made from materials designed to promote the healing of the dental pulp and to encourage secondary dentin formation, which can help protect the pulp tissue. This is particularly important in deep cavities where the risk of pulp exposure is heightened. By stimulating the dentin, liners provide a protective layer that can help maintain the health of the tooth and facilitate the natural healing process.

In addition, while liners may contribute to certain aspects of cavity preparation or protection against sensitivity, their primary role is to support the pulp health and promote dentin regeneration. This is critical in preserving the vitality of the tooth and ensuring successful outcomes from restorative procedures.
