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.
根分叉穿孔是在多根牙根管治疗或桩核预备过程中可能发生的不幸事件。研究表明，目前用于修复这些医源性事故的材料并不理想。根分叉穿孔预后不佳可能是由于细菌渗漏或修复材料缺乏生物相容性。基于对新引入的三氧化矿物凝聚体的最新物理和生物学特性研究，这种材料可能适用于封闭牙髓腔与下方牙周组织之间的交通。这些病例报告支持了这一假设。
