Several types of material have been proposed and used due to their physical, chemi- cal and biological properties. Objective: The aim of this article is to describe a successful endodontic surgical man- agement in which Portland cement was employed as root- end filling material. Methods: A 64-year-old female patient sought professional care due to moderate pain on chewing and previous episodes of swelling in the region of tooth #25. Clinical examination revealed normal periodontal structures and moderate pain during palpation. Radiographic exami- nation revealed poor root canal treatment with a separated instrument at the beginning of the apical curvature. Perira- dicular disease was also observed. Retreatment of root canal was performed and it was not possible to bypass the sepa- rated instrument. After two years, the patient returned show- ing outstanding signs and symptoms in the same region. A new radiographic examination revealed maintenance of the periradicular disease. The surgical procedure using Port- land cement was then proposed and performed. Results: The 5-year follow-up demonstrates treatment success. Conclusion: The results of this case report suggest that Portland cement has the potential to be used as a root-end filling material. Keywords: Retreatment. Oral surgical procedures.
