两种新型根管充填法在下颌第二恒磨牙C形根管中的应用比较

目的 比较常温流动牙胶与热牙胶垂直加压充填法在下颌第二恒磨牙C形根管中的临床应用效果.方法 将67例诊断为C形根管的患者随机分为A、B两组,A组采用常温流动牙胶充填,B组采用热牙胶垂直加压充填,比较两组的根充质量、疼痛程度及1年后的疗效.结果 两组患者的根充质量、疼痛程度及1年后的疗效比较均无显著性差异.结论 常温流动牙胶与热牙胶垂直加压充填法对下颌第二恒磨牙C形根管的充填短期内均有较好疗效.

Comparison between the Applications of Two New Root Canal Obturations in C-shaped Canal in Mandibular Second Molars

Objective To compare the clinical effect of GuttaFlow obturation and that of vertical condensation of gutta-percha obtu-ration in C-shaped canal in mandibular second molars. Methods 67 teeth of C-shaped canals in mandibular second molars were random-ly divided into 2 groups:group A and group B;GuttaFlow obturation was performed in group A while vertical condensation of gutta-per-cha obturation in group B;a comparative study between the 2 groups was made to the quality of root canal obturation, the severity of pain and the curative effect 1 year after treatment. Results There existed no obvious difference in the comparative study between the 2 groups. Conclusions GuttaFlow obturation and vertical condensation of gutta-percha obturation are both of good curative effect on C-shaped canals in mandibular second molars.
