摘　　要：目的:探讨儿童乳牙根管治疗后采用3种牙冠修复方式修复牙体缺损的临床效果。方法:选取2019年1月至2021年1月收治的600例乳牙根管治疗后的患儿为研究对象,采用随机列表法将其分为A组、B组和C组,每组200例。A组患儿采用铸瓷嵌体修复,B组患儿采用金属预成冠修复,C组患儿采用树脂充填修复。结果:A组、B组修复体的完好率高于C组,差异有统计学意义(P<0.05);A组、B组患儿的边缘密合性、邻接关系等牙体修复效果优于C组(P<0.05);B组治疗操作耗时显著短于A组、C组(P<0.05);A组不良反应发生率为8.00%,B组为4.00%,低于C组14.50%(P<0.05)。结论:铸瓷嵌体修复和金属预成冠修复对儿童乳牙根管治疗后缺损的效果优于树脂充填修复。Objective:To investigate the clinical effect of three kinds of crown restoration methods on children′s deciduous teeth after root canal therapy.Methods:A total of 600 children who received root canal therapy in their primary teeth in our hospital from January 2019 to January 2021 were selected as the research objects.They were randomized into Group A,Group B,and Group C,with 200 cases in each group.The ceramic inlays,metal preformed crown and resin fillings were respectively adopted to repair the deciduous teeth in children in Group A,Group B and Group C.Results:The success rate of dental treatment in Groups A and B was significantly higher than that in Group C(P<0.05),the difference was statiscally significant;the effect of dental restoration of Group A and B,including teeth edge tightness,adjacency of teeth,and the like was superior to that of Group C(P<0.05);the operation time of treatment in Group B was significantly shorter than that in Group A and C(P<0.05);the incidence of adverse reactions was 8.00%in Group A and 4.00%in Group B,which was lower than 14.50%in Group C(P<0.05).Conclusion:The effect of ceramic inlays and metal preformed crown in repairing the defects of children′s deciduous teeth after root canal therapy is better than that of resin fillings.
