Abstract：Objective: To investigate the ultrasonic root canal irrigation in the treatment of patients with locally periapical inflammation and clinical results. methods: 100 cases of apical periodontitis patients admitted to hospital from June 2012 to June 2015, according to randomized, divided into two groups, 50 cases in the observation group used ultrasonic root canal irrigation operation, the control group using a handheld K file type before and after treatment were compared intervention, root canal colonies, before and after the intervention inner root canal endotoxin levels and the degree of pain the patient, filling two statistical quality and clinical effectiveness. Results: After the intervention groups root canal colonies were significantly less than before the intervention (P<0.05), and the intervention group was observed after root canal colonies after the intervention than in the control group (P<0.05), two groups within the root canal after intervention endotoxin levels and pain scores were lower than before the intervention (P<0.05), and endotoxin levels after the intervention group was observed within the root canal and post-intervention pain severity score lower than the control group (P<0.05), after treatment in the observation group appropriate charge rate was significantly higher (P<0.05), clinical healing rate of the observation group was significantly higher (P<0.05), non-healing rate was significantly lower than the control group (P<0.05). Conclusion: Ultrasonic root canal irrigation technique can effectively reduce the apical root canal colonies and endotoxin levels in patients with peripheral inflammation, relieve pain in patients, improve clinical outcomes.
