ABSTRACT

Objective To compare the therapeutic effects of AH Plus sealer and Zinc oxide eugenol sealer in root canal treatment.Methods 206 patients with 227 teeth who needed root canal treatment were divided into observation group(103 patients with 114 teeth) and control group(103 patients with 113 teeth) randomly,and observation group and control group received AH Plus sealer and Zinc oxide eugenol sealer,respectively.Results There were 105 teeth filled exactly,4 overfilled,5 underfilled in observation group,and 103 teeth filled exactly,4 overfilled,5 underfilled in control group.No significantly differences in root canal filling was found between observation group and control group (P ＞ 0.05).In postoperative 1 d,there were 97 teeth with no response,9 with mild,6 with moderate,2with severe in observation group,and 83 teeth with no response,14 with mild,9 with moderate,7 with severe in control group.In postoperative 7d,there were 112 teeth with no response,2 with mild in observation group,and 104 teeth with no response,9 with mild in control group.The intensity of acute postoperative reaction of observation group were significantly lower than those of control group in postoperative 1d and 7d,respectively(t =2.2210,P ＜0.05 ;t =2.1711,P ＜ 0.05).In postoperative 6-month and 12-month,the number of teeth judged as being successful were 109 and 106 in observation group,and 107 and 103 in control group.No statistically significant differences in success rates were found between observation group and control group in postoperative 6-month and 12-month,respectively(P ＞ 0.05).Conclusion The root canal treatment using AH Plus sealer,which was considered to be one of ideal root canal filling materials,can significantly reduce the intensity of acute postoperative reaction.
