Development of Sintered apatite by SPS

我们研究了机械暴露的大鼠磨牙在烧结式碳酸钙牙髓切断术中的修复过程。然后将碳酸钙处理结果与氢氧化钙处理结果进行比较。进行活体CT、苏木精-伊红染色和巢蛋白、牙本质基质蛋白-1(DMP-1)、骨桥蛋白免疫反应分析。Micro CT观察牙髓内牙本质样钙化组织的增多。两组诱导的牙髓切断术都导致炎症相关的改变，随后是成牙本质细胞的渐进性分化。

We investigated restitution processes in mechanically exposed rat molar pulp during pulptomy with sintered calcium carbonate. The result of the calcium carbonate treatment were then compared with calcium hydroxide. In vivo CT,Hematovylinand eosin staining and immunoreactivity for nestin.dentin matrix protein-1(DMP-1),and osteopontin were also analyed.. The increment of dentin like calcified tissue in the pulp was observed by Micro CT. Both groups induced pulpotomy resulted in changes associated with inflammation followed by progressive odontoblasts differentistion.
