摘要/Abstract

摘要： 目的　采用Light-Speed LSX根管预备系统对慢性根尖周炎患者采用一次法根管治疗和两次法根管治疗，评估术后2年随访结果，比较二者治疗成功率。方法　300例上下颌慢性根尖周炎患牙随机分为２组，Ａ组为一次性完成根管治疗，Ｂ组分次完成根管预备和根管充填，所有组内患牙均使用Light-Speed LSX根管预备器械进行根管预备，评价患牙术后2年的临床和影像学表现。结果　采用Light-Speed LSX根管预备系统进行根管预备，一次法组138例（93.88%）治愈，两次法组122例（89.05%）治愈；疗效不确定的一次法组5例（3.40%），两次法组9例（6.57%）；治疗失败的一次法组4例（2.72%），两次法组6例（4.38%）。两组治疗成功率的比较采用卡方检验，结果显示两组治疗成功率无统计学差异（P>0.05）。结论　采用Light-Speed LSX根管预备系统对慢性根尖周炎患者采用一次法根管治疗和两次法根管治疗成功率无差异。

Abstract: Abstract: Objective To evaluate and compare the outcomes of Light-SpeedLSX systems in single-visit and two-visit root canal treatment of patients with chronic apical periodontitis after a 2-year follow-up. Methods 300 maxillary and mandibular teeth with chronic apical periodontitis were randomly assigned into two groups. While the teeth of patients in group A were obturated, those in group B were temporarily sealed and obturated one week later. All canals were enlarged with Light-speedLSX root canal instruments. The healing results were clinically and radiographically evaluated 2 years after the operation. Results Of the 300 treated teeth, 138 of 147 teeth (93.88%) in the A group were healed compared with 122 of 137teeth (89.05%) in the B group, curative effects of 5 cases (3.40%) in the A group were classified as uncertain compared with 9 cases (6.57%) in the B group, 4 cases (2.72%) in the A group and 6 cases (4.38%) in the B group were classified as not healed. Chi-square test was used to compare the success rate of the two groups. Statistical analysis of the healing results did not show any significant difference between the groups (P>0.05). Conclusion There was no statistically significant difference between the single-visit and two-visit root canal treatment in patients with chronic apical periodontits prepared by Light-speedLSX root canal instruments.
