[Detection and prevention of nitrous oxide iatrogenic pollution in dental treatments].
Nitrous oxide (N(2)O), also known as laughing gas, is widely used in the dental offices as a common inhaled sedative analgesic gas to reduce anxiety and pain during treatment. Studies have shown that long-term exposure to higher concentrations of laughing gas may have a certain impact on the health of medical staff, while currently research on iatrogenic pollution in applications of laughing gas in oral therapy is not sufficient. ⋯ While, in China, there is little research on the health effects of laughing gas on medical staff and on how to detect and control nitrous oxide pollution. This review is about the hazards, monitoring and control of clinical application of nitrous oxide.
