The Use of Equimolar Mixtures of Nitrous Oxide and Oxygen in Oral Surgery-A Retrospective Study of Patients in a Swiss University Hospital Setting.

Inhaled equimolar nitrous oxide-oxygen procedural sedation used during dental procedures and oral surgery results in high treatment success and satisfaction rates. The administration of additional topical anesthetics helps to reduce the anxiety and stress related to infiltrative anesthesia. Further dedicated studies and prospective trials are needed to confirm these findings.
