The permit held by dentists to administer nitrous oxide inhalation analgesia covers which services?

• A. Nitrous oxide inhalation analgesia, local anesthesia, and anxiolysis sedation.
• B. Only nitrous oxide.
• C. Only local anesthesia.
• D. Radiographs.

Answer: (B)

The main point is that the nitrous oxide inhalation analgesia permit is narrowly scoped to administering nitrous oxide-oxygen to provide analgesia and to monitor the patient during that specific form of minimal sedation. It does not authorize other procedures such as injecting local anesthetics, performing broader anxiolysis beyond what nitrous oxide achieves, or taking radiographs. Local anesthesia requires separate credentials or permits, anxiolysis or additional sedation may require different regulatory approvals, and radiographs are a diagnostic service not covered by this permit. Therefore, the permit covers only the administration of nitrous oxide inhalation analgesia.
