Internal radicular reabsorption in lower premolar: clinical case report

Abstract

Internal inflammatory root resorption is a pathological condition, relatively rare, with an asymptomatic and silent clinical course, considered a challenge in the dental routine. The management used for successful therapy of a permanent tooth affected by internal resorption. Female patient, 17 years old, started endodontic treatment of the lower premolar (45) with internal root resorption, after the planning agreement and consent of the legal guardian. A protocol of 4 sessions of intracanal medication exchange with calcium hydroxide (Ultracal - Ultradent) was followed, modeling with hand files using the staggered technique, abundant irrigation of the canal with 2.5% sodium hypochlorite, and filling with gutta-percha (Denstplay Maillefer) associated with bioceramic endodontic cement (Bio-C Sealer - Angelus). For long-term endodontic success to be possible in a clinical case of internal root resorption, there are determining factors and these are related to the correct diagnosis, treatment used, use of auxiliary chemical substance, exchange of intracanal medication dressings, temporary restorative to keep the canal inert, endodontic cement chosen for filling the canal and the condensation technique used. The endodontist professional has the duty to keep up to date on advanced diagnostic techniques such as computed tomography and new materials developed to assist in the repair process of the reasorptive cavity, so that the tooth affected by the pathology continues to exercise its aesthetic function, phonetic and physiological in mouth.
