Final answer:
If a dentist is physically present when a dental auxiliary is performing an expanded function, the dentist is providing supervision. The dental auxiliary may perform expanded functions under direct supervision of the dentist. Adequate supervision is crucial for patient safety and quality of care.
Step-by-step explanation:
If a dentist is physically present when a dental auxiliary is performing an expanded function, the dentist is providing supervision. Supervision refers to the act of overseeing or monitoring the work of another person. In this case, the dentist is present to ensure that the dental auxiliary is performing the expanded function correctly and safely.
The dental auxiliary may be allowed to perform certain expanded functions under the direct supervision of the dentist. Direct supervision means the dentist must be physically present in the office or treatment room and approve or authorize the dental auxiliary's actions as they occur.
It is important for the dentist to provide adequate supervision during expanded function procedures to ensure patient safety and the quality of care being provided.
