摘　　要：目的探讨超声根管间断荡洗在牙髓血运重建中的临床疗效。方法选取32颗牙髓、根尖周病变年轻恒牙,随机分为实验组与对照组:实验组采用超声根管间断荡洗,对照组采用次氯酸钠根管冲洗。通过观察术前术后临床症状及根尖片检查,评价根尖周病变的变化及牙根发育状况,探讨牙髓血运重建的临床效果。通过分析初诊治疗至矿化物三氧化物凝聚体(MTA)覆盖起始时间,探讨炎症控制时间。结果实验组16颗患牙与对照组16颗患牙临床症状均消失,根尖周病变消除,牙根继续发育。实验组中13颗患牙牙根形成,成功率81.25%,3颗患牙根尖孔缩小,进步率18.75%;对照组中10颗患牙牙根形成,成功率62.50%,6颗患牙根尖孔缩小,进步率37.50%,两组差异无统计学意义(P>0.05)。实验组控制炎症时间为(28.44±5.98)d,对照组控制炎症时间为(34.13±7.17)d,两组差异有统计学意义(P<0.05)。结论超声根管间断荡洗应用于牙髓血运重建,取得较好的临床疗效,并且缩短了炎症控制时间。Objective To investigate the clinical effect of ultrasonic root canal intermittent irrigation in endodontic vascular reconstruction.Methods 32 young permanent teeth with pulp and periapical lesions were randomly divided into two groups(n=32):experimental group was treated with ultrasonic root canal intermittent irrigation and the control group was rinsed with sodium hypochlorite root canal.The changes of periapical lesions and root development were evaluated by preoperative and postoperative clinical symptom observation and radiograph examination,and the clinical effect of endodontic vascular reconstruction was discussed.The time of inflammation control was discussed by analyzing the starting point from the first diagnosis to the date of mineral trioxide aggregate(MTA)coverage.Results The clinical symptoms of the 16 affected teeth in the experimental group and the control group disappeared,the periapical lesions were eliminated,and the root continued to develop.In the experimental group,root formation was observed in 13 of the affected teeth,with a success rate of 81.25%and a reduction rate of 18.75%.In the control group,root formation was observed in 10 of the affected teeth,with a success rate of 62.5%and a reduction rate of 37.5%.There was no difference in the effective rate between the experimental group and the control group(P>0.05).The control time of inflammation was(28.44±5.98)days in the experimental group and(34.13±7.17)days in the control group,with statistically significant differences(P<0.05).Conclusions Ultrasonic root canal intermittent swabbing applied to pulp revascularization can achieve good clinical effect and shorten the time of inflammation control.
