Context: Anxiety and fear of pain are the two major deterrents for which patients avoid dental treatment. Local anesthetic, which forms the foundation for the delivery of pain-free endodontic treatment, does not serve the purpose in anxious patients and requires augmentation with other pharmacological agents. Aims: The aim of this study is to observe the effectiveness of nitrous oxide in alleviating patient anxiety and pain during endodontic treatment of a vital tooth. Settings and Design: The present in vivo study was conducted on sixty healthy patients from the Outpatient Department of Genesis Institute of Dental Sciences and Research, Ferozepur, Punjab, India. Subjects and Methods: Sixty anxious patients having irreversible pulpitis in their lower molar were selected and divided into two groups, namely control group and intervention group, with thirty patients placed in each group. In control group, access opening and pulp extirpation was done under local anesthesia only, whereas in intervention group, access opening and pulp extirpation was done under local anesthesia and nitrous oxide sedation. The anxiety levels of patients, before and after the treatment, were measured using the Modified Dental Anxiety Scale. Pain felt by the patients during administration of local anesthesia and during access opening was measured using the Visual Analog Scale. Statistical Analysis Used: The data were analyzed using ANOVA and paired t-test, and graphical analysis of the data was done. Results: Significant reduction in anxiety and pain levels of patients during endodontic access opening including significant reduction in pain during administration of local anesthesia was observed under nitrous oxide sedation. Conclusions: Conscious sedation with nitrous oxide is a useful technique to add to the armamentarium used in the treatment of teeth with symptomatic irreversible pulpitis.
