What is the function of a liner applicator?

1. To enhance cavity sensation

2. To administer anesthesia in procedures

3. To place materials in cavity preparations

4. To measure tooth sensitivity

The correct answer is: To place materials in cavity preparations

The primary function of a liner applicator is to place materials in cavity preparations. These specialized tools are designed to accurately and efficiently apply dental liners, bases, or other restorative materials directly into the area of a cavity in a tooth. They help ensure that the material is evenly distributed and can easily reach difficult-to-access areas within the cavity. This precision is crucial in restorative dentistry, as proper application of liners or bases can help protect the tooth pulp, reduce sensitivity, and promote healing. Unlike tools used for sensation enhancement or drug administration, or for measuring sensitivity, the liner applicator's primary role is focused strictly on the placement of materials that support the overall dental treatment process.
