玻璃离子水门汀修复髓室底穿孔的临床观察
核心提示：
摘要：
目的: 研究LGIC修复髓室底穿孔的临床效果。方法：将60颗髓室底穿孔患牙随机分为LGIC组(38颗)和对照组(22颗), 穿孔处分别采用LGIC和氢氧化钙充填修复,然后均行根管治疗,并作永久性充填，所有治疗牙均随访观察18-24月。结果: LGIC组成功25颗,进步11颗，失败2颗,其疗效明显优于对照组(p<0.05);医源性和龋源性穿孔之间,其疗效差异无显著性 (p>0.05);穿孔直径小于2mm者及2-3mm者，其疗效均明显优于3mm以上者(p<0.05)。结论: LGIC是修复髓室底穿孔较好的一种材料,其疗效与穿孔大小有关。

Objective：To study clinical effect of
repairing perforations of pulp floor with light glass ionomer cement.Methods:60 teeth with perforations of pulp floor were divided into LGIC group(38) and control group(22). The perforations were repaired with light glass ionomer cement or calcium hydroxide.and all were treated with root canal therapy All treated teeth were followed up for 18-24 months.Results：In the LCIC group there were 25 successful teeth ，11 improved teeth and 2 failed teeth,and Its efficiency was superior to control group (p<0.05).The differences of efficiency between the originated doctors and caries were not statistically signficant (p>0.05),The differences of efficiency in the perforation diameter being smaller than 2mm,from 2 to 3mm and larger than 3mm were great statistically significant (p<0.01). Conclusions：Light glass ionomer cement is considered to be a better material for repairing perforation of pulp floor and Its efficiency related to peforation diameter.
Key words:Light glass ionomer cement perforation of pul
