SONOPS Multicentre Cross-Sectional Study: Study of the Nitrous Oxide Perception and Use in French Dental Students.

Introduction And Aims: EMONO (equimolar oxygen-nitrous oxide mixture) is widely used in dentistry to achieve sedation for dental care. In addition, pure nonmedical nitrous oxide (N2O) has become a very popular psychoactive substance among health students. Thus, for dental students, the perception of a same substance, N2O, which can either be used as medicine in the form of EMONO in their daily practice, or consumed illegally for recreational purposes in the form of pure nonmedical N2O, is of concern.
