Final answer:
Under direct supervision in dentistry refers to the allowance of certain tasks to be carried out by another staff member while the dentist is not physically present in the building, with the understanding that they are available for consultation.
Step-by-step explanation:
When discussing the term under direct supervision in the context of the occupation code for dentistry, it generally means that certain duties can be delegated by a dentist to a subordinate, such as a dental hygienist or dental assistant, and the dentist is not required to be physically present within the building while these duties are performed. Each state may have their own regulations regarding what constitutes direct supervision, so it's important for dental professionals to be familiar with the rules and regulations of their specific state. However, as a broader definition, under direct supervision usually implies that the dentist is available for consultation or assistance if necessary, even if they are not on the premises.
