中文摘要:
      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。
英文摘要:
      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.
