What dental hygiene procedure is permitted in a health care facility without supervision?

Placing dental x-ray film is a procedure that can be performed by a dental hygienist in a health care facility without the need for direct supervision. This aligns with the scope of practice for dental hygienists in Washington State, which allows them to perform certain procedures independently as long as they possess the necessary training and certification.

Dental x-rays are essential for diagnosing various dental conditions, and the ability to take radiographs without direct supervision demonstrates the trust and responsibility placed on dental hygienists. They are trained to ensure that the process is performed safely and accurately, thus minimizing the risk of unnecessary radiation exposure to patients.

In contrast, procedures such as injections of anesthetic agents or administering nitrous oxide typically require supervision from a licensed dentist due to the complexity and potential risks associated with these tasks. Additionally, taking patient medical history, while an important procedure, is often performed in conjunction with other assessments and may require a collaborative effort with the supervising dentist. Understanding these distinctions helps clarify the boundaries of practice and the roles of various dental professionals within a healthcare setting.
