Abstract

The purpose of this study is to comparatively assess the effect of midazolam and nitrous oxide associated with oxygen, in lower third molar extractions, on the change in the anxiety level of patients by salivary cortisol dosage. Twenty-eight male patients underwent lower third molar extraction under sedation with midazolam and nitrous oxide. Objective (salivary cortisol dosage) and subjective (Corah Dental Anxiety Scale) data have been obtained. By salivary cortisol, 40 minutes after midazolam administration, there has been a statistically significant difference compared with the mean baseline value. Midazolam was the most effective sedation method for reducing salivary cortisol level.
