根管穿孔是一种不幸的事件，可能会：发生在根管治疗期间或多根牙预备后。研究表明，目前用于修复这些医源性事故的材料不足。分叉穿孔的预后不良可能是由于细菌渗漏或修复材料缺乏生物相容性所致。根据最近对新引入的三氧化二矿物质聚集体的物理和生物特性研究，该材料可能适合于关闭牙髓腔和下面的牙周组织之间的连通。这些病例报告支持了这一假设。
Furcal perforation is an unfortunate incident that can: occur during root canal therapy or post preparation of multirooted teeth. Studies have shown that the materials currently used to repair these iatrogenic accidents are inadequate. The poor prognosis of furcation perforations is probably due to bacterial leakage or lack of biocompatibility of repair materials. On the basis of the recent physical and biologic property studies of the newly introduced mineral trioxide aggregate, this material may be suitable for closing the communication between the pulp chamber and the underlying periodontal tissues. These case reports support this hypothesis.
