骨形成蛋白复合牙本质陶瓷修复髓室底穿孔的实验研究

Experimental study of reparative effect of bone morphogenetic protein compounded with ceramic dentin on perforation of dental pulp floor

目的：用骨形成蛋白复合牙本质陶瓷修复髓室底穿孔，以氢氧化钙作为对照组。方法：术后６个月观察骨形成蛋白复合牙本质陶瓷修复髓室底穿孔的生物学作用。结果：骨形成蛋白复合牙本质陶瓷具有诱导骨样组织形成。结论：骨形成蛋白复合牙本质陶瓷可以用于修复髓室底穿孔。

Aim: Bone morphogenetic protein compounded with ceramic dentin (BMP/CD) was used to repair the perforation of dental pulp floor, the calcium hydroxide used as control group. Methods: The biological effects of BMP/CD on the perforation of dental pulp floor were observed 6 months postoperation. Results: BMP/CD was able to induce the formation of bone-like tissues. Conclusions: It was possible to use BMP/CD to repair the perforation of dental pulp floor.
