Nitrous Oxide Inhalation
Nitrous oxide is the most commonly used inhalation anesthetic in dentistry. When used alone, it is incapable of producing general anesthesia reliably, but it may be combined with other inhalation and/or intravenous agents in deep sedative/general anesthestic techniques.
As a single agent, it has impressive safety and is excellent for providing minimal and moderate sedation for apprehensive dental patients.
