The clinical application of ultrasonic root canal intermittent irrigation in endodontic vascular reconstruction / 中国医师杂志

ABSTRACT

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.
