Abstract: This study aims to determine radiographically the quality and the periapical status of root canal treatments performed by undergraduate students from an adult population following 6 to 36 months after treatments. The records of 674 clinical cases corresponding to 1097 canals of patients, performed by dental students in a dental faculty, between the years 2007 and 2009 were followed. Among the patients that returned, 596 charts of cases were randomly selected corresponding to 963 root canals and a follow-up of 6 to 36 months. Pré and pós-operative periapical radiographs were collected and in the follow-up radiographs were performed and examined, to classify the quality of the endodontic treatment and periapical status investigated. The treatment is more in the maxillary teeth (62.6%), than in the mandibular teeth (37.4%). The quality of length filling is significantly associate to the dental arch (^2 (1)=9.646;p=0.002); it was adequate in 90.09% in maxillary teeth whereas in mandibular teeth was 81.17%. The periapical bone was considered healthy in 86.9%. In the radiographs analyzed there was no evidence of separated instruments or root canal perforations. The quality of root canal treatment performed by undergraduate dental students was acceptable, without fractures of instruments and perforations and with a success of 86.9%.
