Mineral trioxide aggregate (MTA) is widely used for different perforation repairs, root-end filling, pulp capping and many other endodontic procedures. Because of potential discoloration effect of gray MTA, white MTA has been introduced into endodontic treatment for the same purposes. This study examined the dental pulp responses in dogs to both types of MTA used as a pulp-capping agent. The pulps of 24 teeth of four male dogs were exposed with a No.1 round bur and capped with either gray or white MTA. Histologic analysis was performed one and 2 weeks after treatment. Calcified bridge could be seen 1 week after treatment with both types of MTA, with no significant differences between the two treatments.
三氧化矿物凝聚体（MTA）广泛用于不同的穿孔修复、根尖充填、盖髓及许多其他牙髓治疗程序。由于灰色MTA存在潜在的变色效应，白色MTA已被引入牙髓治疗以用于相同目的。本研究检测了犬牙髓对用作盖髓剂的两种类型MTA的反应。用1号圆钻暴露4只雄性犬24颗牙齿的牙髓，并用灰色或白色MTA覆盖。在治疗后1周和2周进行组织学分析。两种类型的MTA治疗后1周均可见钙化桥，两种治疗之间无显著差异。
