Exodontia of third molars in a single surgery using conscious sedation in an anxious patient: case report

Abstract

The conscious sedation performed by inhaling nitrous oxide gas (N2O) associated with oxygen gas (O2) provides an ideal analgesic and anxiolytic effect for patients who are insecure and anxious to undergo dental procedures. The aim of the present study is to report a clinical case of a single surgery to extract teeth 18, 28, 38, and 48 in an odontophobic patient who undergoes anxiety by using conscious sedation through the inhalation of nitrous oxide gas diluted in oxygen gas. The patient achieved a state of deep relaxation during sedation, with a decrease in his initial heart rate, high oxygen saturation, and low intraoperative bleeding. The authors concluded that conscious sedation using nitrous oxide is an important ally in oral surgeries for anxious patients.
