简要总结
Endodontic failures are not uncommonly encountered despite improvements in routine root canal therapy. Endodontic microsurgery is one way to manage such failure. The placement of a retrograde filling material is considered the most important prognostic factor in endodontic microsurgery. The aim of this study was to investigate the clinical and radiographic outcome of a fast set bioceramic root end filling material in human teeth.
详细描述
Patients who were referred to the endodontic postgraduate clinics in the period between January 2017 till August 2017 were assessed for inclusion in the study according to preset criteria. Endodontic microsurgery was performed following modern techniques including magnification, root resection with minimal angle, ultrasonic root end preparation and placement of a fast set bioceramic putty as retrograde filling material. The case was subsequently evaluated clinically and radiographically at 3, 6 and 12 months. And will be followed subsequently at 2 years and 4 years post treatment.
