摘要
目的针对年轻恒牙根尖周病变患者,研究牙髓血运重建术对牙根管壁厚度的影响。方法选取2017年1月—2018年6月在该院治疗的年轻恒牙根尖周病变患者78例,按照随机数字法分为实验组和参照组,实验组采取牙髓血运重建术,参照组采取根尖诱导形成术,对比两组治疗效果、牙根发育情况和不良反应发生情况。结果实验组治疗有效率为97.44%,参照组治疗有效率为82.05%,实验组治疗效果好于参照组,差异有统计学意义(=5.014,P=0.025<0.05);与治疗前相比,两组治疗后的牙根管壁厚度和牙冠根比均有改善,但是实验组牙根管壁厚度(2.47±0.31)mm大于参照组牙根管壁厚度(2.21±0.36)mm,差异有统计学意义(t=3.418,P=0.001<0.05);实验组牙冠根比(0.77±0.11)大于参照组牙冠根比(0.70±0.05),差异有统计学意义(t=3.618,P=0.000<0.05);实验组不良反应发生率为2.56%,参照组不良反应发生率为15.38%,实验组不良反应发生情况优于参照组,差异有统计学意义(χ^2=3.924,P=0.048<0.05)。结论在对年轻恒牙根尖周病变治疗中,牙髓血运重建术可有效改善临床症状,促进牙根发育,增加牙根管壁厚度,降低牙根折断以及根管内感染的风险。
Objective To study the effect of pulp revascularization on the thickness of root canal wall in young patients with permanent periapical lesions.Methods Seventy-eight young patients with permanent periapical lesions treated in the hospital from January 2017 to June 2018 were selected and divided into an experimental group and a reference group according to the random number method.The experimental group was treated with pulp revascularization,while the control group was treated with apical induction.The treatment effect,root development and adverse reactions of the two groups were compared.Results The treatment effective rate of the experimental group was 97.44%,and the treatment effective rate of the reference group was 82.05%.The treatment effect of the experimental group was better than that of the reference group,comparing the difference between the two groups was statistical significance(χ^2=5.014,P=0.025<0.05),Compared with before treatment,the root canal wall thickness and crown root ratio of the two groups were improved,but the thickness of the root canal wall of the experimental group(2.47±0.31)mm was greater than that of the reference group(2.21±0.36)mm,comparing the difference between the two groups was statistical significance(t=3.418,P=0.001<0.05);the crown root ratio of the experimental group(0.77±0.11)was greater than that of the reference group(0.70±0.05),comparing the difference was statistical significance(t=3.618,P=0.000<0.05);the incidence of adverse reactions in the experimental group was 2.56%,the incidence of adverse reactions in the reference group was 15.38%,and the incidence of adverse reactions in the experimental group was better than the reference group,comparing the difference between the two groups was statistical significance(χ^2=3.924,P=0.048<0.05).Conclusion In the treatment of periapical lesions of young permanent teeth,pulp revascularization can effectively improve clinical symptoms,promote root development,increase root canal wall thickness,and reduce the risk of root fracture and root canal infection.
