【摘要】 目的 :观察生物活性玻璃微粒 (Bioglass)修复髓室底穿孔的临床疗效。 方法 :选择髓室底穿孔病例 75例 ,患牙 86个 ,随机分为两组 ,试验组采用生物活性玻璃微粒 ,对照组采用光固化玻璃离子修复。 1年后观察临床效果。结果 :试验组成功率 81.3% ,进步 13.9% ,对照组成功率 4 6 .5 % ,进步 2 3.3% ,两组间有显著性差异 (P <0 .0 5 )。其疗效与穿孔直径密切相关 ,与穿孔原因关系不明显。结论 :生物活性玻璃微粒是一种良好的髓室底穿孔的修复材料更多还原

【Abstract】 AIM:To observe the clinical effects of repairing the perforation of floor of pulp chamber with Bioglass.METHODS:86 teeth of perforating of floor of pulp chamber from 75 cases were grouped randomly into two by random. Experimental group was treated with Bioglass,the other was treated with light-cured glass cement as control.The effect was obtained 1 year after operation.RESULTS:Successful rate in experimental group was 81.3% and advancement rate was 13.9%,which was significant different from the control group (successful rate was 46.5%,advancement rate was 23.3%,P<0.05).The clinical effect was closely related with the diameter of perforation,and no obvious relationship with cause of perforating.CONCLUSION:Bioglass was a good material to repair perforation of floor of pulp chamber.更多还原
