摘　　要：目的比较年轻恒牙采用两种不同根管充填术的临床疗效。方法将120颗患牙髓病或根尖周病的年轻恒磨牙随机分为两组,每组各60颗,对照组行冷牙胶侧压充填术,实验组行热牙胶垂直加压联合热塑牙胶充填术。观察术后疼痛发生情况、充填效果及1年后牙周膜的改变。结果根充后两组患牙能自行缓解的疼痛发生率分别为11.7%和10.0%。不能自行缓解的疼痛发生率分别为5.0%和3.3%,两组间差异无统计学意义(P>0.05)。对照组适充49颗,超充3颗,欠充8颗;实验组适充50颗,超充7颗,欠充3颗(P>0.05)。术后1年牙周膜增宽分别为2.35%和1.5%,两组间差异亦无统计学意义(P>0.05)。结论两种根管充填术均能达到良好的临床疗效,差异无统计学意义。Objective To compare the clinical effect of young permanent teeth treated with different root canal filling technique.Methods One hundred and twenty young permanent teeth suffering from pulposis and periapical disease were randomly divided into two groups.Each group has sixty teeth.The control group were applied cold lateral condensation,and the experimental group were applied warm vertical condensation.Observe the incidence rate of pain,filling effect and the change of periodontal membrane.Results The incidence rates of pain which can relieve were 11.7% and 10.0% respectively in the above two groups,and the incidence rates of pain which can not relieve were 5.0% and 3.3%.The periodontal membrane became wider by 2.35% and 1.5%.There were all no significant difference between the control and experimental groups.Conclusions The two root canal filling technique had the same clinical effect.
