Endodontic flare-up in patients with endodontic therapy referred to Tehran Dentistry school 2003-2004

Introduction: An ongoing and frequently vexing problem in endodontics is the development of pain and swelling (flare-up) during or after endodontic therapy. Despite significant progress in the field of endodontics, the causes of flare-up are not well defined and are a subject of controversy. The purpose of this study was to determine the incidence of endodontic flare-up. The incidence of flare-up was also examined in relation to patient factors and the quality of treatment performed. Methods: In this cross-sectional study information from the charts of 518 patients who received root canal therapy by undergraduate students in dentistry faculty of Tehran medical science university in years 2003-2004 was recorded and analyzed. All of patients were included in this study with no precondition. No intracanal medicaments were placed interappointment. The chi-square analysis was used to compare the variables and significant level was considered as p<0.05. Results: The results demonstrated 102 (25.3% ) of the 403 patients had a flare-up characterized by swelling or moderate-to-severe pain that begun after the finishing of endodontic treatment. Also 43 (10.2%) of the 518 patients had an interappointment flare-up characterized by swelling or moderate-to-severe pain during the interappointment time interval of Endodontic treatment. We concluded that some factors, such as sex of patients, tooth type. presence of preoperative pain, perforation, and number of appointments had significant effects on the incidence of endodontic flare-up. Conclusion: Because of the great incidence of endodontic flare-up. it is necessary to accentuate it in theoretical endodontic lessons.
