INTRODUCTION
Mineral trioxide aggregate (MTA) was developed because existing materials did not have the ideal characteristics for orthograde or retrograde root-end fillings. MTA has been recommended primarily as a root-end filling material, but it has also been used in pulp capping, pulpotomy, apical barrier formation in teeth with open apexes, repair of root perforations, and root canal filling. Part I of this literature review presented a comprehensive list of articles regarding the chemical and physical properties as well as the antibacterial activity of MTA. The purpose of part II of this review is to present a comprehensive list of articles regarding the sealing ability and biocompatibility of this material.
METHODS
A review of the literature was performed by using electronic and hand-searching methods for the sealing ability and biocompatibility of MTA from November 1993-September 2009.
RESULTS
Numerous studies have investigated the sealing ability and biocompatibility of MTA.
CONCLUSIONS
On the basis of available evidence it appears that MTA seals well and is a biocompatible material.
简介
矿化三氧化物凝聚体（MTA）的研发是因为现有的材料并不具备作为直向或侧向根管充填的理想特性。MTA 主要被推荐作为根管充填材料，但它也被用于盖髓、牙髓切断术、根尖孔未闭合牙齿的根尖屏障形成、修复根管穿孔和根管充填。本文第一部分对 MTA 的化学和物理特性以及抗菌活性进行了全面的文献回顾。本文第二部分的目的是对 MTA 的密封能力和生物相容性进行全面的文献回顾。
方法
对 1993 年 11 月至 2009 年 9 月间关于 MTA 密封能力和生物相容性的文献进行了电子和手工检索。
结果
大量研究调查了 MTA 的密封能力和生物相容性。
结论
根据现有证据，MTA 具有良好的密封性和生物相容性。
