MTA广泛应用于各种根管穿孔的修复、根端充填、盖髓等。由于灰色MTA的潜在变色效应，白色MTA已被引入根管治疗中用于相同的目的。本研究检查了狗的牙髓反应，这两种类型的MTA用作盖髓剂。用1号圆钻暴露4只雄性狗的24颗牙齿的牙髓，并用灰色或白色MTA覆盖。治疗后1周和2周进行组织学分析。两种MTA治疗后1周均可见钙化桥，两种MTA治疗组间差异无统计学意义。
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.
