Short Description
A layer of dental material placed under a filling to protect the tooth’s pulp from heat, pressure, or decay.
Long Description
A cement base is a layer of protective dental material placed inside a prepared tooth cavity before a filling is applied. Its primary role is to insulate the dental pulp—the inner part of the tooth—from temperature changes and pressure.
It also helps provide mechanical support under large restorations, particularly when a lot of natural tooth structure is missing. Cement bases can be made of materials like glass ionomer, zinc oxide-eugenol, or resin-modified compounds.
While not visible in the final restoration, a properly placed cement base contributes to the longevity of the filling, reduces post-operative sensitivity, and supports the overall strength of the restored tooth.
