根管治疗效果与根管封闭剂密切相关，而在充填过程中，很可能存在根管封闭剂超充填的情况。商品化的根管封闭剂种类众多，iRoot SP作为一种新型生物陶瓷类根管封闭剂，因具有良好的生物相容性、封闭性和抗菌性而逐渐被重视，其超充是否会影响患牙的预后也引起了关注。本文总结了iRoot SP理化及生物学性能，以及根管封闭剂超充填的研究进展，结合随访病例分析iRoot SP超充的预后情况。

关键词: 根管充填材料, 根管充填, 预后, iRoot SP

The effect of root canal therapy is closely related to the root canal sealers, and extrusion of sealers occurs to part of cases. iRoot SP, which is a kind of bioceramic root canal sealers, attracts clinical operators′ attentions due to its superior biocompatibility, sealing and antibacterial properties. At the meantime, clinicians come to a question of whether over-obturated iRoot SP affects the tooth prognosis. This article summarized the features of iRoot SP, the research progress of sealer extrusion and several follow-up case reports, in order to analyze the prognosis of iRoot SP over-obturation.
