摘　　要：目的：探讨玻璃离子修复上颌前牙龈下牙体缺损的疗效。方法：选择上颌前牙缺损达龈下且不适合牙冠延长术的患者29例,年龄25~62岁。术前行必要的根管治疗和牙周基础治疗,待牙龈健康后行翻瓣术。翻瓣后,龈下牙体缺损采用玻璃离子修复,龈上缺损采用树脂修复,抛光后缝合。记录术前和术后1、6、12个月SBI和PD指数。结果：29例患者术后1、6、12个月SBI和PD均低于术前（P〈0.05）;术后1、6、12个月SBI和PD无显著差异（P〉0.05）。结论：对上颌前牙龈下牙体缺损病例,采用玻璃离子修复疗效良好。AIM ： To evaluate the clinical effect of glass - ionomer cement restoration in the treatment of sub- gingival defect of upper anterior teeth. METHODS ： 29 patients aged 25 - 62 years were included in this study. Surgical crown lengthening was not suitable for the treatment of subgingival defect in upper anterior teeth of the patients. The pa- tients were treated by root canal therapy and periodontal treatment before operation for the subgingival defect. When gin- gival tissue was healthy, subgingival defects were filled with glass -ionomer cement and supragingival ones with compos- ite resin . The results were evaluated by sulcus bleeding index （SBI） and probing depth （PD） at baseline, 1, 6 and 12 months after treatment. RESULTS ： In all patients, postoperative SBI and PD were significantly lower than that before op- eration （ P 〈 0.05 ）. No significant differences in SBI and PD was found among 1, 6 and 12 months after surgery （P 〉 0.05）. CONCLUSION：Subgingival defect in upper anterior teeth can be filled with glass -ionomer cement and satisfactory effect can be obtained.
