Administering nitrous oxide can improve the effectiveness of inferior alveolar nerve block in patients with symptomatic irreversible pulpitis, according to a study published in the May issue of the Journal of Endodontics.
Researchers at The Ohio State University, working with a private-practice endodontist from North Carolina, conducted a prospective, randomized, double-blind, placebo-controlled study to determine the effect of nitrous oxide on the anesthetic success of the IAN block in patients experiencing symptomatic irreversible pulpitis.
