摘要

Mineral trioxide aggregate(MTA)目前在根管治療方面已有良好的治療應用，包括牙根穿通之修補、牙根尖手術逆向充填之材料、牙根外吸收之修補、甚至牙根尖之封填。近年來，由於此材料的良好生物相容性與封閉性，逐漸擴展應用到乳牙的斷隨治療與未成熟恆牙牙根之牙根尖成形術。因為是新發展之材料，且其兒童牙科之臨床試驗報告只有少數，所以本篇報告之目的在於徹底了解MTA的性質與其在兒童牙科將來可能之應用。(Taiwan J Pediatr Dent 3(1):13-22,2003)

Mineral trioxide aggregate (MTA) has shown favorable clinical results in endodontics including repair of root perforations and root external resorption, material for retrograde filling, and even root-end filling. Recently because of its excellent biocompatibility and sealing ability, MTA had the potential to become a replacement material for treating pulptomy in the primary teeth and apexification in the young permanent teeth. However, it is still a new cement and has very few in vivo clinical studies to draw definitive conclusions. The purposes of this article were to review the physical and chemical properties of MTA, and to understand its possible clinical applications in pediatric dentistry.
