摘要:

目的 比较根管治疗一次法与多次法对感染根管的治疗效果。方法 130例急、慢性根尖周炎或牙髓坏死患者(143颗患牙)按就诊顺序随机分为两组,一次治疗组(n=95)一次性完成根管预备和根管充填,多次治疗组(n=48)则实施常规根管治疗(需复诊1~2次)。根管充填术完成后(一次法治疗组)或初诊封药后(多次法治疗组)24 h,采用视觉模拟评分法(VAS)由患者对疼痛程度进行自我评定。一次法治疗组根管充填完成后1周复诊,多次法治疗组初诊封药后1周和根管充填完成后1周分别复诊,对疼痛水平进行临床评定。根管充填完成后6个月和1年时复诊,经X线检查结合临床情况进行疗效评估。结果 两组患者疼痛情况的自我评定结果比较差异无统计学意义(P>0.05),一次和多次治疗组的急性反应发生率分别为10.53%和12.5%(P>0.05);两组疼痛情况的临床评定结果比较差异无统计学意义(P>0.05)。根管充填完成后6个月和1年,一次治疗组的治疗成功率为83.3%和88.5%,多次治疗组的治疗成功率分别为88.9%和90.5%,组间比较差异均无统计学意义(P>0.05)。结论 对于感染根管实施一次法根管治疗,术后近期疼痛发生情况及治疗效果与多次法比较无明显差异,具有临床可行性。

Abstract:

Objective To compare the short-term effects of single-visit and multi-visit root canal therapy for infected root canals. Methods One hundred and thirty patients (143 teeth) with acute and chronic periapical inflammation or pulp necrosis were randomly divided into single-visit root canal therapy group (n=95, root canal preparation and filling in one visit) and multi-visit root canal therapy group (n=48, conventional root canal therapy with 1 to 2 subsequent visits). Twenty-four hours after root canal filling (single-visit root canal therapy group) or intracanal medication in first visit (multi-visit root canal therapy group), the pain degree was self-assessed by patients with visual analogue scale (VAS). In single-visit root canal therapy group, subsequent visit was done 1 week after root canal filling, and the pain degree was clinically evaluated. In multi-visit root canal therapy group, the pain degree was clinically evaluated during subsequent visits 1 week after intracanal medication and 1 week after root canal filling respectively. Six months and 1 year after root canal filling, the therapeutic effect was determined with X-ray examination and clinical assessment. Results There was no significant difference in the degree of pain self-assessed by patients (P>0.05), and the incidences of acute reaction were 10.53% and 12.5% in single-visit root canal therapy group and multi-visit root canal therapy group respectively (P>0.05). There was no significant difference in the degree of pain in clinical evaluation (P>0.05). Six months and 1 year after root canal filling, the cure rates were 83.3% and 88.5% in single-visit root canal therapy group, and those were 88.9% and 90.5% in multi-visit root canal therapy group, with no significant difference between two groups (P>0.05). Conclusion For infected root canals, single-visit root canal therapy may yield similar short-term postoperative pain and therapeutic effect with multi-visit root canal therapy.
