根尖周炎应用热牙胶充填和侧压充填治疗临床效果比较

Comparison of the Clinical Effect of Hot Gutta-percha Filling and Lateral Condensation in the Treatment of Periapical Periodontitis

目的比较根尖周炎应用热牙胶充填和侧压充填治疗的临床效果。方法 180例根尖周炎患者分别运用热牙胶充填(90例)与侧压充填(90例)治疗,分别作为本研究的对照组与研究组,比较两组患者的临床治疗效果。结果研究组的根管充填时间为(1.96±0.31)min,对照组的充填时间为(3.77±0.84)min,研究组治疗的总有效率为93.33%,对照组治疗的总有效率为81.11%,差异比较均具有统计学意义(P<0.05)。结论根尖周炎应用热牙胶充填治疗的临床效果比侧压充填更优。

Objective To compare the clinical effect of hot gutta-percha filing and lateral condensation in the treatment of periapical periodontitis.Methods 180 cases of periapical periodontitis patients were treated with hot gutta-percha（90 cases）and lateral condensation（90 cases）respectively,as the control group and the study group of the study. The clinical outcomes of the two groups were compared.Results The root canal filing time of the study group was（1.96±0.31）min,and that of the control group was（3.77±0.84）min. The total effective rate of study group was 93.33%,and that of control group was 81.11%,the differences were statisticaly significant（P〈0.05）.Conclusion The clinical effect of hot gutta-percha filing is better than lateral condensation in the treatment of periapical periodontitis.
