Conscious sedation is a technique in which one or more pharmacological agents are employed to produce a mild depression in the central nervous system, without loss of consciousness so that verbal contact can always be maintained with the patient; this allows for certain dental procedures to be performed.
The technique is associated with a great margin of safety.
In Odontopediatrics, the sedative agents generally employed are nitrous oxide (N2O) and benzodiazepines, amongst other agents with sedative properties.
The use of nitrous oxide/oxygen (N2O) is becoming more frequent for general and pediatric procedures in dental medicine and has become common practice in many countries.

Nitrous oxide, or protoxide of nitrogen (N2O), is a colorless gas with a sweetish taste. It has an anxiolytic and sedative effect, and also promotes muscular relaxation and analgesia.
