Pain and flare-up after endodontic treatment procedures

Eglė Sipavičiūtė, Rasmutė Manelienė

Summary

Flare-ups can occur after root canal treatment and consist of acute exacerbations of an asymptomatic pulpal and/or periradicular pathologic condition. The causative factors of interappointment pain encompass mechanical, chemical, and/or microbial injury to the pulp or periradicular tissues. Microorganisms can participate in causation of interappointment pain in the following situations: apical extrusion of debris; incomplete instrumentation leading to changes in the endodontic microbiota or in environmental conditions; and secondary intraradicular infections. Interappointment pain is almost exclusively due to the development of acute inflammation at the periradicular tissues in response to an increase in the intensity of injury coming from the root canal system. The mechanical irritation of apical periodontal tissue is caused by overinstrumentation of the root canal and filling material extrusion through the apical foramen. Incorrectly measured working length of the root canal has inherent connection with these causative factors of endodontic flare – up. This review article discusses these many facets of the flare-up: definition, incidence causes and predisposing factors.

Key words: endodontic treatment, flare-up, acute exacerbation, postoperative pain, root canal infection.
