【摘要】 目的：评估老年人牙隐裂伴慢性牙髓炎患牙根管治疗术后5年的临床疗效，并探讨其相关影响因素。方法：收集2016年1月至2016年12月牙隐裂伴慢性牙髓炎的老年患者114例，共114颗患牙，行根管治疗术。术后5年回访，采用回顾性研究评估患牙治疗效果，同时对影响因素进行相关性分析。结果：术后5年回访103例患者，老年人牙隐裂伴慢性牙髓炎患牙5年有效存留率为90.3%，患牙有效存留率与隐裂纹深度、分布、牙周状况、是否冠修复具有显著相关性(P<0.05)，与患者年龄、性别、牙位、患牙是否存在明显磨耗、根管治疗就诊次数等无相关性(P> 0.05)。结论：对于老年人牙隐裂伴慢性牙髓炎患牙，可通过患牙隐裂纹分布、隐裂纹深度、牙周状况评估该类患牙的预后，术后定期回访督促患者及时行全冠修复，提高患牙有效存留率。更多还原

【Abstract】 Objective: To evaluate the clinical efficacy of root canal therapy in elderly patients with cracked teeth complicated with chronic pulpitis for 5 years, and to explore its related influencing factors. Methods: A total of 114 teeth diagnosed as cracked teeth with chronic pulpitis were included and analyzed retrospectively. Root canal therapy effects were evaluated after 5-year follow-up. The inductive summary method and correlation analysis method were used to identify the main factors of cracked teeth with chronic pulpitis. Results: There were 103 patients evaluated after 5-year follow-up. The overall survival rate was 90.3%, The effective survival rate of the affected teeth was significantly correlated with the depth and distribution of the cracks, periodontal status, and crown restoration(P <0.05), but not with the age, gender, tooth position, tooth wear, and treatment times of root canal therapy(P>0.05). Conclusion: The therapeutic effects of cracked teeth with and chronic pulpitis can be efficiently predicted by the crack distribution, depth and periodontal status. Postoperative visit and crown restoration can increase the survival rate of cracked teeth with chronic pulpitis.更多还原
