    Author: Ogawa Y, Misaki T.

    Abstract:
    Frequency of using nitrous oxide (N2O) in anesthetic field decreased recently by the influence of the environmental problems and the widespread use of intravenous agents. In dental treatment, however, inhalation sedation using low concentration of N2O has been effectively used to relax dental patients. Nitrous oxide inhalation sedation for dental treatment generally involves the use of a combination of low-dose N2O and high-dose oxygen. Low-dose N2O induces the relaxation of psychological tension in dental patients who have "dental phobia". Also, high-dose oxygen would contribute to manage "(pre) syncope" due to pain stimuli. Thus, N2O inhalation sedation is effective for the dental treatment, although the leak of N2O affects the health of dental staffs. The present review described the advantage and harmful effects of N2O in dental management.
