Which procedure is not typically delegated to dental hygienists?

Diagnosing dental conditions is not typically delegated to dental hygienists because this task specifically requires the dental hygienist to have the authority to make clinical judgments regarding a patient’s oral health and to define the diagnosis. In many states, including Oklahoma, the practice acts reserve the role of diagnosis exclusively for licensed dentists, who must evaluate patient conditions and determine treatment plans.

In contrast, procedures such as prophylaxis, curettage, and dental hygiene counseling fall within the scope of practice for dental hygienists. Prophylaxis involves the removal of plaque and calculus from the teeth, which is an essential part of preventive care. Likewise, curettage, which pertains to the cleaning of periodontal pockets, is also within the hygienist’s responsibilities, allowing them to assist in the management of periodontal disease. Dental hygiene counseling is an educational component where hygienists advise patients on oral health practices, which is also a standard part of their role.

Thus, the clear distinction lies in the authority and training required for diagnosing conditions, which is reserved for dentists, while hygienists are tasked with other important preventive and supportive roles in patient care.
