Which statement about independent practice for dental hygienists is true?

• A. Yes, with a professional corporation
• B. Yes, if licensed in another state
• C. No, cannot practice independently
• D. No, must be employed by a dentist

Answer: (D)

In this state, dental hygienists are not allowed to practice independently; they must work under the supervision of a licensed dentist. The dentist is responsible for the overall care plan and signs off on the procedures performed by the hygienist, so even if a hygienist operates within a professional corporation or holds licenses from another state, that does not create independent practice authority in Louisiana. The supervising dentist–hygienist relationship ensures there is a licensed clinician overseeing all dental hygiene services. That means the true statement is that a dental hygienist cannot practice independently and must be employed by a dentist.
