| 观察玻璃离子水门汀和氢氧化钙联合修复髓室底穿孔的临床疗效。［方法］ 髓室底穿孔患牙73颗，用氢氧化钙糊剂和玻璃离子水门汀覆盖穿髓孔，然后行常规根管治疗及窝洞充填。［结果］ 在所有73颗患牙中，共治愈62颗，总的治愈率为84.9 %。医源性髓底穿孔患牙的治愈率为89.1 %；龋源性髓底穿孔的治愈率为77.8 %。穿髓孔径小于2 mm的患牙的治愈率为89.2 %；在穿髓孔径大于2 mm的患牙的治愈率为80.6 %。两者之间的差异均无显著性。 ［结论］ 采用玻璃离子水门汀和氢氧化钙联合修复髓室底穿孔是一种有效的治疗方法 |

| Abstract: |
| To investigate clinical effects of repairing perforations of pulp floor with glass ionomer cement and calcium hydroxide. ［Methods］ The perforations of pulp floor of 73 cases in molars were repaired with glass ionomercement and hydroxide calcium. Repaired teeth were treated for endodontics according to traditional method. ［Result］ Among the total of 73 teeth, 62 teeth were considered to be successful. The successful rate was 84.9%. ［Conclusion］ It's effective to repair perforation of pulp floor with glass ionomer cement and calcium hydroxide. |
