Effects of one-time root canal filling using AH-Plus canal sealer and iRoot SP canal sealer in patients with chronic apical periodontitis
Objective To compare the therapeutic effects of using epoxy resin-based canal sealer(AH-Plus)versus bioceramic iRoot SP in the root canal treatment for patients with chronic apical periodontitis.Methods Ninety patients with chronic apical periodontitis treated in Department of Conservative Dentistry and Endodontics,Hospital Affiliated to Yan'an University from May 2021 to October 2022 were selected for the randomized controlled trial,and were divided into a control group and an observation group by the random number table method,with 45 cases in each group.There were 24 males and 21 females in the control group;they were(28.14±6.02)years old;their disease course was(3.26±0.92)months.There were 22 males and 23 females in the observation group;they were(26.55±5.78)years old;their disease course was(3.45±0.79)months.The control group took root canal treatment with AH-Plus sealer and warm vertical compaction of gutta-percha,while the observation group were treated with iRoot SP sealer and took warm vertical compaction of gutta-percha.The efficacies,pain scores[Visual Analog Scale(VAS)],masticatory function(masticatory efficiency and absorption values in masticatory tests)before and after the treatment,and patient satisfaction were compared between the two groups.t and x2 tests were applied.Results The total effective rate in the observation group was higher than that in the control group[97.78％(44/45)vs.73.33％(33/45)],with a statistical difference(x2=10.879;P＜0.001).The scores of VAS 12,24,and 72 h after the treatment in the observation group were lower than those in the control group(1.52±0.19 vs.2.35±0.26,2.65±0.31 vs.3.80±0.29,and 3.29±0.20 vs.4.15±0.23),with statistical differences(t=15.142,18.173,and 18.928;all P＜0.05).There was no statistical difference in the mastication efficiency between the two groups before the treatment(P＞0.05).After the treatment,the mastication efficiency in the observation group was higher than that in the control group[(85.21±11.22)％vs.(72.76±10.23)％],with a statistical difference(t=5.500;P＜0.05).The total satisfaction rate with the treatment in the observation group was higher than that in the control group[95.56％(43/45)vs.77.78％(35/45)],with a statistical difference(x2=6.154;P=0.013).Conclusion Compared with AH-Plus root canal sealer,iRoot SP canal sealer in root canal treatment for patients with chronic apical periodontitis is more effective and can reduce post-operative pain,and improve masticatory function and patient satisfaction.
