Which of the following functions may not be delegated to a dental assistant II in North Carolina?

In North Carolina, specific functions within dental practice are regulated to ensure the safety and competency of professionals. The delegation of tasks to dental assistants is categorized based on the level of training and certification that an assistant has achieved.

The correct function that may not be delegated to a dental assistant II is the intramural use of a high-speed handpiece. This task involves significant clinical skill and understanding of dental procedures, as it directly impacts patient care. High-speed handpieces are used for procedures that necessitate a close working knowledge of dental anatomy and the treatment process. Consequently, only licensed dentists or dental hygienists who have completed the appropriate education and licensure requirements can operate a high-speed handpiece within the oral cavity.

On the other hand, tasks such as performing cleanings, operating x-ray equipment, and scheduling patient appointments are within the scope of practice for a dental assistant II, provided they have the necessary training and certification. These tasks can be performed under the supervision of a licensed dentist, and they do not require the same level of clinical judgment and skill as the use of a high-speed handpiece. Therefore, it is essential for dental practices to adhere to these regulations to maintain high standards of patient care and safety.
