Occupational exposure to nitrous oxide (N2O) was measured during dental treatment in 120 children (3 to 7 years). Whereas air conditioning of the clinic was held constant, additional suctioning at the site of surgery ( = 30), rubber dam (n = 30), both (n = 30), or neither measure (n = 30) was applied. Active suctioning with or without additional rubber dam is able to minimize pollution to a degree where recommendations (25 ppm on an eight-hours average) are met. Rubber dam alone fails to provide low N2O exposure. Without active suctioning, daily time of treatment should be limited.
