摘要
目的探讨富血小板纤维蛋白(PRF)牙髓血运重建术与根尖诱导成形术治疗年轻恒牙牙髓坏死的效果。方法选取2019年1月至2021年6月江西省萍乡市人民医院口腔科收治的80例年轻恒牙牙髓坏死患儿作为研究对象,采用随机数字表法分为诱导组(n=40,患牙40颗)和重建组(n=40,患牙40颗)。诱导组患儿行根尖诱导成形术,重建组患儿行PRF牙髓血运重建术。比较两组患儿治疗前、治疗6、12个月牙根长度、牙根面积及根管壁厚度,患儿家属满意度评分及疗效。结果重建组及诱导组患儿治疗6、12个月牙根长度均长于两组治疗前,牙根面积大于两组治疗前,根管壁厚度高于两组治疗前,差异有统计学意义(P<0.05);重建组治疗6、12个月牙根长度长于诱导组,牙根面积大于诱导组,根管壁厚度高于诱导组差异有统计学意义(P<0.05);重建组患儿家属对咬合度、咀嚼功能、色泽、整体美观满意度评分均高于诱导组家属,差异有统计学意义(P<0.05);重建组总有效率高于诱导组,差异有统计学意义(P<0.05)。结论PRF牙髓血运重建术与根尖诱导成形术相比,对年轻恒牙牙髓坏死治疗效果更佳,有助于促进牙体发育,患儿家属满意度更高。
Objective To investigate the effects of pulp revascularization with platelet-rich fibrin(PRF)and apexification in the treatment of immature permanent teeth with pulp necrosis.Methods A total of 80 children with pulp necrosis of immature permanent teeth who were admitted to the Department of Stomatology,Pingxiang People's Hospital from January 2019 to June 2021 were selected as the research subjects.According to random number table method,the subjects were divided into induction group(n=40,40 affected teeth)and reconstruction group(n=40,40 affected teeth).Children in the induction group were treated with apexification,while children in the reconstruction group were treated with pulp revascularization with PRF.Compare the root length,root area and root canal wall thickness of the two groups before treatment,6 months after treatment and 12 months after treatment,as well as the satisfaction score and curative effect of the children's family members.Results After 6 months of treatment and 12 months of treatment,the root length of children in the reconstruction group and the induction group was longer than that before treatment,the root area was larger than that before treatment,and the thickness of root canal wall was higher than that before treatment,the differences were statistically significant(P<0.05).After 6 months of treatment and 12 months of treatment,the root length of the reconstruction group was longer than that of the induction group,the root area was larger than that of the induction group,and the root canal wall thickness was higher than that of the induction group,and the differences were statistically significant(P<0.05).The satisfaction scores of the family members of the children in the reconstruction group on the degree of occlusion,masticatory function,color and overall beauty were higher than those of the family members in the induction group,and the differences were statistically significant(P<0.05).The total effective rate of the reconstruction group was higher than that of the induction group,a
