摘要

目的：比较3种不同类型牙隐裂纹树脂粘接修复术后2年的临床效果。方法：将91例患者的95颗发生隐裂的上颌第1磨牙根据隐裂纹类型分为3组，磨除隐裂纹后使用光固化复合树脂粘接修复，比较术后2年不同裂纹组的治疗效果。结果：经2年定期随访，复合树脂粘接修复成功率单端裂纹组为86.1%，贯通裂纹组为76.7%，混合裂纹组为48.1%，贯通裂纹组与其余两种裂纹组比较无显著性差异，而混合裂纹组和单端裂纹组比较有显著性差异，主要体现在牙髓保存效果和充填体保存效果两个方面。结论：隐裂牙树脂粘接修复的预后效果与隐裂纹的类型密切相关。

Abstract

Objective：To compare the efficacy of composite restoration in the treatment of three kinds of cracked teeth at 2 years after the operation. Methods：According to experimental method and types of crack，95 cracked maxillary first molars were divided into 3 groups. All the teeth were restored with a composite restoration and the curative effects of different kinds of cracked teeth were com－pared at 2 years after the operation. Results：With 2-year follow-up，the success rate of single cracked group was 86.1% while pen－etrating cracked group was 76.7% and mixed cracked group was 48.1%. Results showed that the curative effect of mixed crack was obviously lower than that of single crack after 2 years，mainly concerning pulp survival and restoration survival，but no significant difference was observed between penetrating crack and other crack. Conclusion： Prognosis of cracked tooth is closely related to the type of crack.
