目的：观察 Dyad Flow 自粘接流动树脂在乳牙龋齿治疗中的临床效果。方法：纳入206个患者的317颗患龋乳磨牙，随机分成3组。所有患牙都用微创车针结合手动挖匙备洞，A 组（n ＝107）用 Dyad Flow 自粘接流动树脂充填；B 组（n ＝104）用3M流动树脂和自酸蚀粘结剂充填，C 组（n ＝106）用玻璃离子水门汀充填。1年及2年后随诊，观察效果。结果：A、B、C 3组治疗完成1年成功率分别为95．3％、96．77％和91．84％（P ＞0．05），2年成功率分别为89．19％、90．67％和79．45％（P ＞0．05）。结论：Dyad Flow 自粘接流动树脂在乳牙龋治疗中可以获得很好的效果。%Objective:To observe the effects of Dyad Flow self-adhering flowable composite in the minimal invasive treatment of decid-uous molar caries.Methods:31 7 deciduous molars caries of 206 patients were randomly divided into 3 groups and treated by minimal invasive method,the cavities of the molars were filled with Dyad Flow self-adhering flowable composite(group A,n =1 07),traditional flowable composite and self-etching adhesive(group B,n =1 04)and glass ion(group C,n =1 06)respectively.The children were fol-lowed up for 1 and 2 years after treatment.Results:1 year after treatment the success rate(%)of group A,B and C was 95.3,96.77 and 91 .84(P >0.05);2 years after treatment 89.1 9,90.67 and 79.45(P >0.05),respectively.Conclusion:Dyad Flow self-adhe-ring flowable composite is effective in the treatment of deciduous molar caries.
