Abstract
Objective To investigate the clinical effect of root canal filled epoxy resin paste in the treatment of periapical periodontitis. Methods From January 2017 to January 2018, 60 cases of periapical periodontitis in the Fourth People's Hospital of Tongxiang were selected and divided into two groups according to the random table method, with 30 cases in each group.The observation group was treated with root canal filling with epoxy resin paste, while the control group was treated with traditional root canal paste.The two groups were first examined by X ray examination before treatment, to determine the periodontal root tip condition, conventional pulp opening, root canal preparation and irrigation, and pullout.The pain effects of the two groups after 1 week of treatment were compared, and the efficacy of 6 months after treatment was compared. Results The pain level 0 in the observation group at 1 week after treatment (66.67%) was significantly higher than that in the control group (36.67%)(μ=5.41, P=0.019). The effective rate at 6 months after treatment in the observation group (90.00%) was higher than that in the control group (63.33%) (μ=5.96, P=0.013). Conclusion The root canal filling epoxy resin paste has significant clinical effect in the treatment of periapical periodontitis, and it is worthy of clinical application.
