What is another name for nitrous oxide/oxygen analgesia used in dentistry?

1. Oral sedation

2. Inhalation sedation

3. IV sedation

4. Topical sedation

The correct answer is: Inhalation sedation

Nitrous oxide/oxygen analgesia is commonly referred to as inhalation sedation in the context of dentistry. This method involves the patient inhaling a combination of nitrous oxide and oxygen, which provides a calming effect and helps alleviate anxiety during dental procedures. The inhalation route allows for rapid onset and easy monitoring of the patient's sedation level, making it a preferred choice in many dental practices. Inhalation sedation is distinguished from other forms of sedation such as oral sedation, which involves administering a sedative drug orally; IV sedation, where a medication is delivered directly into the bloodstream via intravenous injection; and topical sedation, which involves applying a local anesthetic to the surface of the tissue. Each of these methods has its own applications and considerations, but the term "inhalation sedation" specifically pertains to the use of nitrous oxide and oxygen.
