中文摘要：

BioAggregate是近年来出现的一种新的根管治疗材料，可用于根管倒充填术、穿孔修补术、活髓治疗等。BioAggregate与广为熟悉的三氧化矿物凝聚体（MTA）相比，具有某些特殊的性质。本文围绕Bio-aggregate近年来的研究进展，从化学结构、生物相容性、根尖封闭能力、抗微生物能力等方面对其作一综述，并与MTA进行全面比较。

英文摘要：

BioAggregate （BA）is a newly developed material for endodontic treatment.It is recommended for clinical applications including retrograde root filling,perforation repair,vital pulp therapy,etc.Compared with the well-known mineral trioxide aggregrate （MTA）,BA possesses some distinctive features.This article reviews the re-cent research progress on BA from the aspects of chemical composition,biocompatibility,capacity of root-end sealing and antimicrobial effect.A comprehensive comparison between BA and MTA are made in this review.
