Endodontic interappointment emergency (EIE) occurs in a low incidence following treatment by qualified operators. The purpose of this study was to assess the incidence of EIE after treatment by undergraduate students and to examine its correlation with preoperative and operative parameters. Randomly selected 334 records were retrospectively surveyed for unscheduled emergency appointments following endodontic treatment by undergraduate students. Treatment included step-back canal preparation in multiple visits with formocresol interappointment dressing. The incidence of EIE was 4.2%, and unrelated to the patients' sex and age or to tooth location. It was significantly higher in nonvital than in vital teeth (p < 0.05), with the highest occurrence in nonvital teeth unassociated with periapical radiolucency. Clinically, EIE was associated with swelling in half of the cases. It is concluded that the incidence of EIE following treatment by undergraduate students is low and related to tooth vitality.
