Who is permitted to administer nitrous oxide inhalation analgesia?

The option indicating that dental hygienists are permitted to administer nitrous oxide inhalation analgesia under direct supervision is correct because it acknowledges the regulatory framework that governs dental professionals' practices. In many jurisdictions, dental hygienists are trained and authorized to administer nitrous oxide, but they must do so under the direct supervision of a licensed dentist.

Direct supervision means that the dentist must be present in the office and available to oversee the procedure, ensuring that the patient is monitored and that safety protocols are adhered to. This requirement for supervision helps maintain a standard of care and patient safety, which is particularly important when administering any form of sedation.

In contrast, other positions, such as dental assistants, typically do not have the authority to administer nitrous oxide without appropriate supervision or training specific to that practice, which is why those options don't align with accepted dental law and regulations. Understanding these regulations helps clarify the roles and responsibilities of different dental professionals in a clinical setting.
