Dental workers are exposed to nitrous oxide (N2O) during administration of this anesthetic gas to patients. Exposures should be minimized to prevent short-term behavioral and long-term reproductive health effects that can be produced by N2O. NIOSH research has shown controls including system maintenance, ventilation, and work practices can effectively reduce N2O concentrations in dental operations to approximately 25 ppm during analgesia administration, the exposure limit recommended by NIOSH. Uncontrolled exposures to N2O have exceeded 1000 ppm.
