本文报道了直接放置在猪乳牙牙髓上的各种磷酸钙材料。使用光学显微镜和未脱钙切片的显微X线检查，测试了以下盖帽剂：磷酸三钙加镁、50%磷酸三钙-50%羟基磷灰石和磷酸八钙，并以氢氧化钙为参考材料。结果表明，磷酸三钙加镁和磷酸八钙可诱导类似于牙本质发育不全甚至血管牙本质的营养不良性牙本质的形成。与氢氧化钙相比，50%磷酸三钙加50%羟基磷灰石化合物可提供最佳的牙本质生成效果，导致修复性牙本质桥更厚，正常管状牙本质形成更快。
This article reports on various calcium phosphate materials placed directly on the dental pulp of pig primary teeth. The following capping agents were tested, using light microscopy and microradiography of undecalcified sections: tricalcium phosphate plus magnesium, 50% tricalcium phosphate-50% hydroxylapatite, and octocalcium phosphate, with calcium hydroxide being used as a reference material.The results show that tricalcium phosphate plus magnesium and octocalcium phosphate induce formation of a dystrophic dentin similar to that of dentinogenesis imperfecta or even vasodentin. Compared with calcium hydroxide, the 50% tricalcium phosphate plus 50% hydroxylapatite compound provides the best dentinogenetic effects, resulting in a thicker reparative dentin bridge and quicker formation of normal tubular dentin.
