一次性与多次性根管治疗慢性根尖周炎的效果比较(1)
[摘要]目的 探討慢性根尖周炎患者应用一次性根管治疗和多次性根管治疗的临床效果。方法 选取2016年2月～2017年2月我院口腔科收治的98例慢性根尖周炎患牙作为研究对象，采用随机数字表法将其分为实验组和参照组，每组各49例。参照组应用多次性根管治疗，实验组则采取一次性根管治疗。比较两组术后7 d疼痛发生情况以及1年内的根尖周临床治疗效果。结果 术后7 d，两组均无3级疼痛发生，实验组和参照组两组术后疼痛率总发生率分别为16.3%、18.4%，差异无统计学意义(P>0.05)。术后1年复诊，实验组治愈40例，有效7例，治疗总有效率为95.9%；参照组治愈40例，有效7例，治疗总有效为93.9%，两组总有效率比较差异无统计学意义(P>0.05)。结论 对慢性根尖周炎患者应用一次性根管治疗的临床效果和术后疼痛与多次性根管治疗相近，但一次性根管治能减少患者的就诊次数，缩短治疗时间，值得临床进行推广。

[Abstract] Objective To investigate the clinical effect of one-time canal therapy and multiple root canal therapy in patients with chronic periapical periodontitis. Methods A total of 98 cases of chronic periapical periodontitis were selected from February 2016 to February 2017. According the random digital table method， they were divided into experimental group and reference group， 49 cases in each group. The patients in the control group were treated with multiple root canal therapy， while the patients in the experimental group were treated with one-time root canal therapy. The incidence of 7 d pain and the effect of periapical periodontal treatment in the two groups were compared. Results On the 7 day after operation， there was no grade 3 pain in the two groups. The total incidence of postoperative pain in the experimental group and the control group was 16. 3% and 18.4%， respectively. There was no significant difference in the incidence of pain between the two groups (P>0.05). One year after operation， 40 cases were cured and 7 cases were effective in the experimental group， the total effective rate was 95.9% in the control group； 40 cases were cured and 7 cases were effective in the reference group， and the total effective rate was 93.9%. There was no significant difference in the total effective rate between the two groups (P>0.05). Conclusion The clinical effect and postoperative pain in patients with chronic apical periapical periodontitis are similar to that of multiple root canal therapy， but one-time root therapy can reduce the number of visits and shorten the time of treatment. It is worth popularizing in clinic.
