Características radiográficas dos casos encaminhados para retratamento endodôntico na UNISC.

Abstract

The present study aims to evaluate and describe the radiographic characteristics of endodontic failures that had indication of retreatment in the UNISC Dentistry School. For this, the information of the medical registers of 183 patients who received referral to the extension project with emphasis on endodontic retreatment between 2012 and 2017 were used. About this people, were excluded all that who hadn’t quality radiographic exams available on it. Retrospective dates were observed and recorded. Demographic datas such as age and sex were collected. The analyzes were realized with the primary radiographic cases’ images. They were classified according to the limit of the obturation (adequate or inadequate), quality of compaction of the obturator material (satisfactory or unsatisfactory), periapical radiolucency (present or absent), and presence of unsealed duct. After evaluating 183 cases, 53 cases of endodontic retreatment were selected, where the mean age was 49 years old, 56.60% female and 43.40% male; the obturation limit was inadequate in 54.84% of the cases; the quality of obturation was unsatisfactory in 77.42% of those evaluated; in 53.23% there was apical radiolucency; and in 32.26% of the teeth there were presence of unsealed ducts. Among the factors described, the highest percentage of failure was because of the quality of the obturation, followed by the obturation limit, the presence of periapical lesions and the presence of untreated ducts, as well as those treated unsatisfactorily were the highest frequencies in cases of retreatment. The extravasation of obturator material was the less frequent factor in cases referred for retreatment.
