Clinical efficacy of washing C-shaped root canal with ethylene diamine tetraacetic acid combined with sodium hypochlorite
Objective To explore the clinical effect of washing C-shaped root canals with ethylene diamine tetraacetic acid combined with sodium hypochlorite. Methods 74 cases of mandibular second molar with chronic apical periodontitis from April to August 2017 were selected. The patients treated with root canal were divided into the experimental group and the control group according to the principle of random distribution. The patients in the experimental group were treated with ethylene diamine tetraacetic acid combined with sodium hypochlorite to wash C-shaped roots tube, the control group of patients were treated with saline combined with hydrogen peroxide to wash C-shaped root canal. Results After 6 months follow-up, the recovery rate was 73% in the experimental group and 43.2% in the control group. After one year of follow-up, the efficiency of the experimental group was 85.7%, and 60% in the the control group, the difference was statistically significant (P<0.05). Conclusion The treatment of washing the C-shaped root canal with Ethylene diamine tetraacetic acid combined with sodium hypochlorite had better effect.
