Final answer:
The question asks about specific dental procedures that can only be conducted by a licensed dentist, not delegable to others, which likely includes tasks as administering anesthesia and handling infectious risks.
Step-by-step explanation:
The subject of the question pertains to the scope of professional duties that can be delegated by a dentist to other staff members within a dental practice. Specifically, it appears the question is inquiring about procedures that are exclusively within the purview of a licensed dentist and cannot be delegated to unlicensed individuals. Considering the context provided, these procedures likely involve complex and sensitive tasks such as administering anesthesia, performing extractions, or other invasive maneuvers. An important factor in such delineations is the potential risk of infections or complications, which require a high level of professional training to manage. By mentioning needle sticks, the question also invokes concerns about occupational hazards faced by health professionals, including dentists, which underscores the importance of proper licensure in performing certain dental procedures.
