【摘要】 目的:比较预成根管钉和铸造桩核在老年人前后牙修复时的操作时间及成功率。方法:随机选择需做桩核或根管钉修复的老年病人,记录操作时间,随访观察成功率。结果:后牙的桩核修复操作时间均长于预成根管钉(P<0.001);前牙桩核与根管钉操作时间2组差异无显著性(P>0.05);前牙桩核修复成功率高于预成根管钉(P<0.05);后牙桩核修复和预成根管钉修复2组差异无显著性(P>0.05)。结论:在老年患者前牙首选桩核,后牙首选根管钉。更多还原

【Abstract】 Objective:To compare by-chair time and success rate between canal pins or casting post-core in restoration of anterior and posterior teeth in elderly patients. Methods:The elderly patients were randomly received canal pins or casting post-core therapy. The by-chair time was recorded. Follow-up were performed. Results: The by-chair time of casting post-core was longer than canal pins in restoration of posterior teeth (P <0.001), there was no significant difference between casting post-core and canal pins used in anterior teeth (P >0.05). The success rate of casting post-core used in anterior teeth was higher than canal pins (P <0.05), no significant difference between casting with post-core and canal pins used in posterior teeth (P > 0.05). Conclusion:Casting post-core was more appropriate than canal pins used in anterior teeth in elderly patients, and canal pins was better than casting post-core for posterior teeth in elderly patients.更多还原
