Development of Sintered apatite by SPS

我们研究了烧结碳酸钙对机械暴露的大鼠臼齿切除后的修复过程。并将碳酸钙处理的结果与氢氧化钙进行了比较。体内CT、血凝素和伊红染色及巢蛋白、牙本质基质蛋白-1（DMP-1）和骨桥蛋白的免疫反应性分析。显微CT观察牙本质样钙化组织在牙髓内的增加。两组诱导的牙髓切开术均导致与炎症相关的变化，随后是成牙细胞的进行性分化。

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.
