【摘要】 目的：分析评价年轻恒牙的牙髓及根尖周病变患者采取牙髓血运重建术结合CBCT检查技术治疗的临床效果。方法：本次将佛山市顺德区第二人民医院口腔科就诊的根尖孔未闭的牙髓病变或根尖周病的年轻恒牙患者40例为研究对象，入选时间为2017年1月-2018年8月，按随机数字表法将其分为两组，分组前均于术前拍CBCT片存档，A组采取牙髓血运重建术治疗，B组采取根尖诱导成形术治疗，比较两组临床手术治疗效果。结果：A组手术成功率为90.00%，明显高于B组的45.00%，差异有统计学意义（P<0.05）。手术前，两组患牙冠根比、患牙根管壁厚度比较，差异均无统计学意义（P>0.05）;手术后，A组患牙冠根比、患牙根管壁厚度均明显优于B组，差异有统计学意义（P<0.05）。结论：在临床中，针对年轻恒牙的牙髓及牙根尖周病变患者，采取牙髓血运重建术结合CBCT检查技术治疗的效果优良，可提高手术成功率，改善病变，促进恒牙再发育，值得采纳及应用。

【Abstract】 Objective：To analyze and evaluate the clinical effect of pulp revascularization combined with CBCT in young permanent teeth with pulp and periapical lesions.Method：A total of 40 cases of young permanent teeth with pith lesions or periapical periodontal disease treated in the Department of Stomatology of the Second Peoples Hospital in Shunde District of Foshan City were selected from January 2017 to August 2018.They were divided into two groups according to random number table method.Before grouping，CBCT films were taken for archiving.Group A was treated with pulp revascularization.Group B was treated with apical induction plasty.The clinical effect of surgical treatment was compared between the two groups.Result：The success rate of operation in group A was 90.00%，which was significantly higher than 45.00% in group B，the difference was statistically significant（P<0.05）.Before operation，there was no significant difference in crown root ratio and root canal wall thickness between the two groups（P>0.05）.After active operation，the crown root ratio and the thickness of root canal wall in group A were significantly better than those in group B，the differences were statistically significant（P<0.05）.Conclusion：In clinic，pulp revascularization combined with CBCT is effective in treating pulp and periapical lesions of young permanent teeth，which can improve the success rate of operation，pathological changes and promote the development of permanent teeth.It is worth adopting and applying.

年轻恒牙牙根在发育期间，如果受到一些因素的影響，比如畸形、龋坏或外伤等，会致使出现牙髓根尖周病变，当牙根发育终止的情况下，进一步会发生较多的危害，包括：根尖孔敞开、根管壁薄弱及牙根变短等[1]。为了促进恒牙再发育，有必要针对该类疾病患者采取有效的医治方案。本研究将笔者所在医院在2017年1月-2018年8月收治的40例根尖孔未闭的牙髓病变或根尖周病的年轻恒牙患者作为研究对象，其目的是分析评价牙髓血运重建术结合CBCT检查技术在其中的应用效果，具体研究成果如下。
