The purpose of a linear applicator in dental procedures is specifically to place materials such as calcium hydroxide or glass ionomer in cavity preparations. This applicator is designed to allow for precise and controlled placement of these dental materials into the cavity, ensuring that they fill the prepared space adequately. Calcium hydroxide is commonly used for its properties in promoting healing and providing a barrier to pulp exposure, while glass ionomer serves to seal the cavity and can release fluoride to help prevent further decay.

While other options may involve tools or techniques used in dental practices, they do not accurately describe the specific function of a linear applicator. For example, applying adhesive directly to the tooth or administering local anesthesia typically requires different instruments and techniques. Similarly, measuring the depth of a cavity involves tools like periodontal probes rather than a linear applicator. Thus, option B correctly identifies the specialized use of a linear applicator in dental procedures.
