Premedication can also lessen patients' fears and soothe both patient and practitioner. This will lead to a better treatment in a shorter time. Prior to premedication, medical history should be obtained completely and an oral, inhalation or iv method of premedication is chosen according to sex, weight and the degree of anxiety of patients.  NO2 is very safe method for premedication.

It should be taken into consideration that premedication cannot eliminate all the fears and anxiety and dentist should use other techniques of controlling fear as well.
