1、氢氧化钙碘仿糊剂根尖诱导成形临床研究邢燕张新明黄红琼李海风任权枝潘佩瑜(佛山市第五人民医院口腔科528200)(佛山市医学科学技术研究项目)【摘要】目的:对氢氧化钙碘仿糊剂在根尖诱导成形过程中的作用及意义进行深入研究。方法:收集我院门诊2012年2月-2013年5月因外伤、龋坏或畸形中央尖导致牙髓或根尖周感染,牙根未能发育完全的年轻恒牙患者110人,共计124例患牙,随机分为两组,在控制根管感染及尖周炎症的基础上,实验组采用氢氧化钙碘仿糊剂进行根尖诱导成形,对照组采用氢氣化钙糊剂进行诱导,术后3个月、6个月复查拍片对比两者诱导牙根继续发育效果。结果:根尖诱导3个月拍牙片复查实验
2、组氢氧化钙碘仿糊剂根尖诱导69例患牙中47例牙根基木发育,有效率68.12%,对照组氢氧化钙糊剂根尖诱导55例患牙中牙根基木发育32例,有效率58.18%,差异有统计学意义(P<0.05);根尖诱导6个月拍牙片复查,实验组氢氧化钙碘仿糊剂根尖诱导69例患牙中45例牙根发育完成,有效率65.22%,对照组氢氧化钙糊剂根尖诱导55例患牙中28例牙根发育完成,有效率50.91%,差异有统计学意义(P<0.05)o结论:对年轻恒牙牙根未完全发育患者的根尖进行成形诱导时,釆用氢氧化钙碘仿糊剂作为诱导药剂,不仅可以减少根尖病症的岀现,同时还可以促进牙根继续发育和根尖形成,因此,氢氧化钙碘仿
