Abstract:
Objective To evaluate the effect of one-visit endodontic treatment for infected root canals with combination of nickel-titanium instruments and ultrasonic technique and warm vertical technique.Methods According to treatment,90 teeth were randomly divided into experimental and control groups.Two groups were used nickel titarlium root canal preparation.Experimental group:51 teeth for ultrasonic root canal irrigation,and warm vertical technique was employed to fill the root canal.Control group:39 teeth for rinse syringes,and warm vertical technique was employed to fill the root canal.Washing fluid was 2％ sodium hypochlorite.The root canal filling was observed after a week and one year of postoperative pain response.Results A week later,two groups of post-operative pain showed that there was significant difference in responses (x2 =15.525,P ＜ 0.05).One year later,the two groups showed no significant difference in efficacy(x2 =0.085,P ＞ 0.05).Conclusion The combination of nickel-titanium instruments and ultrasonic irrigation technique and warm vertical obturation,for the treatment of infected root canals was a method to complete the root canal filling,could reduce both the number of patients subsquent visits and the postoperative pain response,while it could improve the quality of root canal filling.
