Which procedure requires the use of fluoride varnishes under general supervision?

The application of topical fluorides, including fluoride varnishes, falls under general supervision in Florida's dental hygiene regulations. General supervision means that the dentist has authorized the procedure, but the dentist does not need to be physically present in the office when the dental hygienist performs it. This is significant because it allows dental hygienists to provide preventive care and enhance patient oral health through fluoride applications effectively.

Fluoride varnishes are utilized to help in the prevention of dental caries by providing a concentrated dose of fluoride directly to the tooth surfaces. The ability for dental hygienists to apply fluoride varnish under general supervision reinforces their role in promoting preventive care and education in dental practices.

In contrast, other procedures listed, such as securing archwires or monitoring nitrous oxide, typically require direct supervision by a dentist due to the complexity or safety concerns involved. For example, these tasks may involve interactions that require immediate dental judgment or interventions that could pose risks to the patient if not performed under the supervision of a licensed dentist. Cementing temporary crowns also generally necessitates direct oversight due to similar reasons. Thus, the specific allowance for applying topical fluorides under general supervision highlights the regulatory framework that recognizes the preventive capabilities of dental hygienists.
