This study describes 6 cases of endodontic overfilling with successful clinical outcomes during long-term (up to 35 years) radiographic follow-up. Successful endodontic treatment depends on proper shaping, disinfection, and obturation of root canals. Filling materials should completely fill the root canal space without exceeding the anatomical apex. Overfilling may occur when the filling material extrudes into the periapical tissues beyond the apex. The present case series describes 6 root canal treatments in which overfilling of root canal sealer and gutta-percha accidentally occurred. Patients' teeth were periodically checked with periapical radiographs in order to evaluate the outcomes during long-term follow-up. All cases showed healing and progressive resorption of the extruded materials in the periapex. The present cases showed that if a 3-dimensional seal was present at the apical level, overfilling did not negatively affect the long-term outcomes of root canal treatment.
本研究描述了6例根管超充病例，在长达35年的影像学随访中临床结果成功。成功的根管治疗取决于根管的适当预备、消毒和充填。充填材料应完全充满根管空间且不超出根尖解剖位置。当充填材料超出根尖孔挤入根尖周组织时可能发生超充。本病例系列描述了6例意外发生根管封闭剂和牙胶超充的根管治疗。定期用根尖片检查患者牙齿，以评估长期随访结果。所有病例均显示根尖周挤出材料愈合并逐渐吸收。本病例表明，如果根尖水平存在三维封闭，超充不会对根管治疗的长期结果产生负面影响。
