目的比较矿物三氧化物聚合体（MTA）和氢氧化钙作为盖髓材料在人牙中的应用效果。方法对11对年龄在20 ~ 25岁的上颌第三磨牙进行机械性牙髓暴露。暴露的牙髓用MTA或氢氧化钙覆盖，用ZOE覆盖，并用汞合金修复。共14颗牙齿在1周后拔除（两颗臼齿），2个月（三颗臼齿），3个月（5颗臼齿），4个月（两颗臼齿）和6个月结果组织学检查显示MTA较氢氧化钙能减少炎症、充血和坏死，增加牙本质桥的厚度和成牙本质细胞层的形成。建议进行更多样本量更大的研究并进行更长时间的随访。
Aim To compare mineral trioxide aggregate (MTA) with calcium hydroxide when used as pulp-capping materials in human teeth.Methodology Eleven pairs of maxillary third molars in subjects between 20 and 25 years of age were subjected to mechanical pulp exposure. The exposed pulps were capped with MTA or calcium hydroxide, covered with ZOE and restored with amalgam. A total of 14 teeth were extracted after periods of 1 week (two molars), 2 months (three molars), 3 months (five molars), 4 months (two molars) and 6 months (two molars).Results Histological evaluation demonstrated less inflammation, hyperaemia and necrosis plus thicker dentinal bridge and more frequent odontoblastic layer formation with MTA than calcium hydroxide.Conclusions Although the results favour the use of MTA, more studies with larger samples and a longer follow up are suggested.
