纤维桩辅桩修复前磨牙薄弱根管的临床评价

摘要

Objective To evaluate and compare the clinical effects of accessory fiber post and metal cast post-core in restoration of first premolar weakened root canal. Methods Select 48 patients(56 teeth) as the experimental object,whose maxillary first premolar was weakened root canal.All teeth were randomly divided into experimental group(32 teeth)and control group(24 teeth),the experimental group were restored with RTD fiber posts and accessory fiber posts,while the control group were restored with cast metal post-core. After 2 years followed-up the results were evaluated according to post core restoration success rate and patient satisfaction. Results In the experimental group, only 1 loosen post case,none post fall,break or root fracture?cases,the success rate was 96.9;in the control group,2 post loosen cases,2 post loss cases and1 root fracture case,the success rate was 79.2%.It was statistically significant difference between the two groups data (P<0.05).The patients satisfaction rate in experimental group is 93.7,in control group is 77.7,it was significant difference between the two groups data(P<0.05). Conclusion Accessory fiber post can be used as an effective method of restoration in premolar weakened root canals, it is worthy of clinical application.%目的：评价比较纤维桩辅桩和金属铸造桩核修复第一前磨牙薄弱根管的临床效果。方法：选择上颌第一前磨牙为薄弱根管的患者48例（56颗患牙）作为实验对象。随机分为实验组（32颗）和对照组（24颗）。实验组采用纤维桩主桩加辅桩修复，对照组采用金属铸造桩核修复，随访2年，评价桩核的修复成功率和患者的整体满意度。结果：实验组桩核仅1例出现松动，未见桩核脱落、折断和牙根折裂等情况，成功率为96.9%；对照组桩核2例松动，2例脱落，1例牙根折裂，成功率为79.2%，两组数据差异有统计学意义（P<0.05)。患者整体满意度：实验组满意率达93.7%，对照组满意率达77.7%，两组数据差异有统计学意义（P<0.05）。结论：纤维桩辅桩可以作为一种有效的修复前磨牙薄弱根管的方法，值得临床应用。
