Nitrous oxide-oxygen sedation in dental treatment has been used to a limited extent at the dental schools in Oslo and Bergen since the middle of the 1970-ies. Anesthetists were responsible for the sedation until 1983. Since then two dentists at the pedodontic departments, one in Oslo and one in Bergen, have been licensed for the use of nitrous oxide. ⋯ The acceptance and cooperation from the patients were better with low concentrations of nitrous oxide than at higher levels. The side effects/complications were few and mild (4.1%). This study shows that nitrous oxide-oxygen sedation in dental treatment is excellent and safe for many patients that cannot be treated conventionally.
