摘　　要：目的 探讨牙髓血管再生术与根尖诱导成形术治疗年轻恒牙外伤致牙髓坏死的临床疗效。方法 便利选取2019年1月—2022年1月济宁市第三人民医院收治的88例年轻恒牙外伤致牙髓坏死患儿为研究对象,采用随机数表法分为研究组和对照组,各44例。研究组开展牙髓血管再生术治疗,对照组开展根尖诱导成形术治疗。比较两组临床疗效、牙髓活力、牙根发育状况,记录治疗前、末次随访时患牙根管长度和根冠壁厚度,统计两组并发症发生情况。结果 研究组总有效率为90.91%,较对照组(75.00%)高,差异有统计学意义(χ^(2)=3.938,P<0.05)。末次随访时,研究组牙髓活力阳性率、牙根继续发育率较对照组高,差异有统计学意义(P均<0.05)。末次随访时,两组的牙根管长度较治疗前增长,牙根管壁厚度较治疗前增厚,且研究组优于对照组,差异有统计学意义(P均<0.05)。研究组并发症发生率较对照组低,差异有统计学意义(P<0.05)。结论 牙髓血管再生术治疗年轻恒牙外伤致牙髓坏死的临床疗效优于根尖诱导成形术,不仅能够提高牙髓活力,还能够促进牙根的继续发育,且并发症发生率较低,安全性较好。Objective To investigate the clinical efficacy between pulp angioplasty and apical induced angioplasty in the treatment of pulp necrosis caused by trauma of young permanent teeth.Methods A total of 88 young children with endodontic necrosis due to permanent tooth trauma treated in Jining Third People's Hospital from January 2019 to January 2022 were conveniently selected as the study objects and divided into study group and control group by ran-dom number table method,with 44 cases in each group.Pulp angioplasty was performed in the study group,and apical induction angioplasty was performed in the control group.The clinical efficacy,pulp activity and root development of the two groups were compared.The length of the root canal length and the thickness of the root crown wall were re-corded before treatment and at the last follow-up.The incidence of complications in the two groups was analyzed.Results The total effective rate of the study group was 90.91%,which was higher than that of the control group(75.00%),and the difference was statistically significant(χ^(2)=3.938,P<0.05).At the last follow-up,the positive rate of pulp activity and the rate of continued root development in the study group were higher than those in the control group,and the differences were statistically significant(both P<0.05).At the last follow-up,the root canal length and the wall thickness of the root canal in both groups increased compared with that before treatment,and the study group was better than the control group,and the differences were statistically significant(all P<0.05).The complication rate of the study group was lower than that of the control group,and the difference was statistically significant(P<0.05).Conclusion Pulp angioplasty has better clinical efficacy than apical induced angioplasty in the treatment of pulp ne-crosis caused by trauma of young permanent teeth.It can not only improve pulp vitality,but also promote the continu-ous development of tooth roots,and has a low complication rate and good safety.
