Which dental material is effective for sealing dentinal tubules?

Glass ionomer is effective for sealing dentinal tubules due to its unique properties. This material has a chemical bond with tooth structure, allowing it to adhere tightly to dentin and enamel. Glass ionomer releases fluoride over time, which can help remineralize the surrounding tooth structure and prevent further sensitivity or decay. The ability to penetrate and seal the dentinal tubules effectively reduces the permeability of the dentin, thus lessening the sensitivity that can occur with exposed dentinal tubules. Additionally, glass ionomer is biocompatible and can provide a protective barrier for the dental pulp, making it a suitable choice in restorative practices where dentinal tubules need to be sealed effectively.
