Nitrous oxide is a safe and effective conscious sedative for dental patients, reducing anxiety and pain. While its use as a general anesthetic has declined, it remains valuable in modern dentistry.

Area of Science:

  • Dentistry
  • Anesthesiology
  • Pharmacology

Background:

  • Nitrous oxide has a long history of use in dental anesthesia.
  • Current dental practices rarely use nitrous oxide for general anesthesia.
  • Its application as a conscious sedative is widespread and successful.

Purpose of the Study:

  • To review the historical and current applications of nitrous oxide in dentistry.
  • To assess the safety and efficacy of nitrous oxide as a conscious sedative.
  • To highlight its role in managing dental anxiety and pain.

Main Methods:

  • Literature review of nitrous oxide's clinical use in dentistry.
  • Analysis of its application as a conscious sedative versus general anesthetic.
  • Examination of reported side effects and patient outcomes.

Main Results:

  • Nitrous oxide is extensively used as a conscious sedative in contemporary dentistry.
  • It effectively reduces patient anxiety and provides supplemental analgesia.
  • Hypoxic general anesthetic techniques with nitrous oxide are uncommon in the US.

Conclusions:

  • Nitrous oxide is a remarkably safe and effective agent when used appropriately in dentistry.
  • Its primary role is as a conscious sedative, not a general anesthetic.
  • The agent demonstrates a low incidence of side effects given its widespread use.
