Washington State Dental Hygiene (DH) Drug & Law Practice Exam

In Washington State, a Dental Hygienist is permitted to take diagnostic impressions under close supervision. This level of supervision indicates that a licensed dentist must be physically present in the office while the dental hygienist performs the procedure. Close supervision ensures that the dentist is readily available to guide and manage the patient's care during the impression-taking process, which is crucial for ensuring the quality and appropriateness of diagnostic materials used in patient treatment.

It's important to understand that while general supervision allows for more independence, it does not require the dentist to be on-site, which is not suitable for all procedures, particularly those that involve diagnostic impressions. Furthermore, complete prohibition from performing certain tasks is reserved for levels of supervision that are stricter, which do not allow hygienists to carry out these kinds of duties at all. The element of close supervision provides both a safety net for the patient and a framework for professional practice that keeps the dentist involved in the patient's treatment plan while allowing hygienists to utilize their skills effectively.
