title: A comparison of one versus two appointment endodontic therapy in teeth with non-vital pulps.
abstract: A clinical study using upper central incisors was carried out to evaluate the incidence of postoperative pain after root canal preparation by the double-flared technique. Sixty teeth with necrotic pulps from 48 patients whose ages ranged from 12 to 65 years were prepared and filled in either one or two appointments. No difference was observed in the incidence of postoperative pain between the two groups.
