Applying cavity liners and bases and desensitizing agents is classified under what level of expanded function?

The task of applying cavity liners and bases, as well as desensitizing agents, falls under Level 1 expanded functions. In the context of dental hygiene, Level 1 tasks involve foundational procedures that are essential to preparing the tooth for restoration or providing relief from sensitivity. These functions are typically the first additional skills that dental hygienists may acquire beyond the core services of scaling and polishing.

Cavity liners and bases are used to protect the pulp of the tooth and provide a better foundation for restorative materials. Desensitizing agents are applied to alleviate sensitivity to stimuli such as temperature changes or sweet foods. Mastering these functions is fundamental for dental hygiene practice, as they directly contribute to patient care and comfort.

In contrast, higher levels of expanded functions involve more complex and technical procedures that require advanced training and skills. Thus, knowing that applying cavity liners, bases, and desensitizing agents is categorized under Level 1 helps establish a clear understanding of the foundational roles dental hygienists play in patient treatment and collaborative care within a dental practice.
