When can a dental assistant apply sealants?

A dental assistant applying sealants under expanded function level 2 is a practice that allows them to perform specific procedures with a defined level of independence, following proper training and certification. In Iowa, expanded functions for dental assistants enable them to provide additional services beyond basic assisting roles, including the application of sealants, which is a preventive measure used to protect teeth from decay.

This practice is grounded in the recognition that sealants can significantly enhance oral health, especially in children and adolescents, by preventing cavities in the pits and fissures of teeth. The state regulations are established to ensure that qualified individuals perform such procedures effectively and safely.

In contrast, needing a dentist's approval, restrictions to adult patients only, or limiting the application to dental emergencies does not align with the scope of practice allowed for a dental assistant with expanded functions. The regulatory framework supports allowing specifically trained individuals to perform tasks like sealant application without continuous direct supervision, enabling them to contribute more effectively to patient care and preventive dentistry.
