牙髓血运重建术治疗年轻恒牙感染的临床效果探讨

The clinical effect of pulp revascularization in the treatment of infected young permanent teeth

目的分析并研究年轻恒牙感染采取牙髓血运重建术治疗的临床效果。方法64例年轻恒牙感染患儿,按分别抽样法分为对照组和研究组,每组32例。对照组采取根尖诱导成形术治疗,研究组采取牙髓血运重建术治疗。比较两组患儿临床疗效,诊疗前后牙根管壁厚度及牙冠根比,不良反应发生情况。结果研究组患儿的总有效率为96.88%,明显高于对照组的75.00%,差异具有统计学意义(P<0.05)。诊疗前,两组患儿牙根管壁厚度及牙冠根比比较,差异无统计学意义(P>0.05);诊疗后,研究组患儿牙根管壁厚度及牙冠根比均显著优于对照组,差异具有统计学意义(P<0.05)。研究组患儿的不良反应发生率为3.13%,显著低于对照组的21.88%,差异具有统计学意义(P<0.05)。结论年轻恒牙感染采取牙髓血运重建术治疗效果显著,可改善相关症状,促进牙根发育,亦能规避牙根折断等并发症,应用可行性强,值得借鉴。

Objective To analyze and study the clinical effect of pulp revascularization in the treatment of infected young permanent teeth.Methods A total of 64 children with infected young permanent teeth were divided into control group and research group according to the sampling method,with 32 cases in each group.The control group was treated with apexification,and the research group was treated with pulp revascularization.The clinical efficacy,root canal wall thickness and crown-to-root ratio before and after diagnosis and treatment,and occurrence of adverse reactions were compared between the two groups.Results The total effective rate of the research group was 96.88%,which was obviously higher than 75.00%of the control group,and the difference was statistically significant(P<0.05).Before diagnosis and treatment,there was no statistically significant difference in root canal wall thickness and crown-to-root ratio between the two groups(P>0.05).After diagnosis and treatment,the root canal wall thickness and crown-to-root ratio of the research group were significantly better than those of the control group,and the difference was statistically significant(P<0.05).The incidence of adverse reactions of the research group was 3.13%,which was significantly lower than 21.88%of the control group,and the difference was statistically significant(P<0.05).Conclusion Pulp revascularization has a significant effect for infected young permanent teeth,which can improve related symptoms,promote root development,as well as avoid complications such as root fracture.It is feasible and worthy of reference.
