Which of the following cannot be applied by a licensed dental assistant?

In the context of dental practice in Minnesota, a licensed dental assistant is permitted to perform various supportive functions to aid in patient care, but there are clear boundaries regarding certain procedures and the administration of medications.

The administration of intravenous drugs is generally outside the scope of practice for a dental assistant. This involves complex medical procedures requiring extensive training and certification, typically reserved for licensed dentists or healthcare providers with specific training in intravenous therapy.

Conversely, licensed dental assistants are trained and allowed to apply topical anesthetic, topical fluoride, and cavity varnish. These procedures involve localized treatment that can be effectively managed by dental assistants, enhancing patient experience and contributing to preventive oral health care.

Therefore, the lack of allowance for a dental assistant to administer intravenous drugs emphasizes the importance of regulated practices in maintaining patient safety and proper dental care standards.
