摘　　要：目的探讨新型根管冲洗剂(mixture of doxycycline citric acid and detergent,MTAD)协同次氯酸钠对年轻恒牙牙髓血运重建术疗效的影响。方法选取东南大学附属中大医院江北院区2020年5月—2022年1月首次确诊为年轻恒牙牙髓病患儿120例作为研究对象,根据治疗方法将患儿分为2组,观察组与对照组,每组60例。观察组患儿采用MTAD协同次氯酸钠牙髓血运重建术治疗,对照组患儿采用MTAD牙髓血运重建术用于治疗,比较2组患儿治疗前及治疗12个月后的根管壁厚度、冠根比、咬合力、牙龈指数(gingival index,GI)、牙周指数(periodontal index,PI)、咀嚼功能,比较2组患儿的平均愈合时间、临床效果、术后并发症和满意度。结果治疗前,2组患儿的根管壁厚度、冠根比、咬合力、GI、PI和咀嚼功能差异无统计学意义(P>0.05),治疗后,2组患儿的根管壁厚度、冠根比、咬合力、咀嚼功能均增加,差异有统计学意义(P<0.05),GI、PI均降低,差异有统计学意义(P<0.05),与对照组比,观察组患儿的根管壁厚度、冠根比、咬合力、咀嚼功能均明显增加,差异有统计学意义(P<0.05),GI、PI均明显降低,差异有统计学意义(P<0.05)。与对照组比,观察组患儿的平均愈合时间和术后并发症总发生率明显减少,差异有统计学意义(P<0.05),总有效率和总满意度明显增加,差异有统计学意义(P<0.05)。结论采取MTAD协同次氯酸钠用于年轻恒牙牙髓病患儿对年轻恒牙牙髓血运重建术治疗效果比较显著。Objective To investigate the effect of a new type of root canal irrigation(mixture of doxycycline citric acid and detergent,MTAD)combined with sodium hypochlorite on pulp revascularization for young permanent teeth.Methods From May 2020 to January 2022 in Jiangbei Courtyard,Zhongda Hospital Affiliated to Southeast University,120 children with young permanent dental pulp disease diagnosed for the first time were selected as research objects.The patients were divided into 2 groups by different methods,the observation group and control group,60 cases in per group.The children in observation group were used MTAD combined with sodium hypochlorite pulp revascularization,the children in the control group were used MTAD pulp revascularization.The root canal wall thickness,crown-to-root ratio,occlusal force,gingival index(GI),periodontal index(PI),masticatory function of 2 groups were compared before treatment and after 12 months of treatment.The average healing time,clinical effect,postoperative complications and satisfaction were compared between 2 groups.Results Before treatment,there was no significant difference in root canal wall thickness,crown-to-root ratio,occlusal force,GI,PI and masticatory function between 2 groups(P>0.05).After treatment,the thickness,crown-to-root ratio,occlusal force and chewing function in 2 groups were all increased,the differences were statistically significant(P<0.05),GI and PI in 2 groups were all decreased,the differences were statistically significant(P<0.05).Compared with the control group,the root canal wall thickness,crown-to-root ratio and occlusal force and mastication function were significantly increased in the observation group,the differences were statistically significant(P<0.05),GI,PI were significantly decreased in the observation group,the differences were statistically significant(P<0.05).Compared with the control group,the average healing time,the postoperative complications rate in the observation group were significantly reduced,the differences were statistically sig
