【摘要】 目的 探讨儿童乳磨牙邻面龋用树脂填充、金属预成冠修复效果。方法 按随机数字表法将南阳市口腔医院行乳磨牙邻面龋修复患儿78例分为参考组和研究组，每组各纳入患者39例。参考组行传统树脂填充修复，研究组行金属预成冠修复。对比两组修复效果、咬合能力、咀嚼效率、并发症。结果 研究组修复优良率较参考组高，差异有统计学意义（P<0.05）；两组修复后6个月最大咬合面积、咀嚼效率、最大咬合力均高于修复前，而研究组最大咬合面积、最大咬合力、咀嚼效率，高于参考组差异有统计学意义（P<0.05）；研究组修复后并发症发生率较参考组低（P<0.05）。结论 金属预成冠修复乳磨牙邻面龋成功率较高，能够有效改善患儿的咬合能力，助力患儿更高效地咀嚼食物，切实提升咀嚼效率，显著降低修复体松动、脱落、继发龋等并发症的发生几率，在儿童口腔疾病治疗领域具有较高的应用价值。更多还原

【Abstract】 Objective To investigate the effect of resin filling and metal precrown on dental caries in children’s deciduous teeth.Methods According to random number table method,78 children who underwent molar dental caries were divided into reference group and study group.Selected 39 patients in each group were included.The reference group underwent traditional resin-filled restoration,and the study group underwent metal precrown restoration.The repair effect,occlusal ability,masticatory efficiency and complications were compared between the two groups.Results The excellent repair rate of the study group was,which was higher than that of the reference group,with statistical difference(P<0.05).There was no significant difference in occlusal ability and masticatory efficiency between the two groups before repair(P>0.05).The maximum occlusal area,masticatory efficiency and masticatory force of the two groups were higher than those before repair 6 months after repair,while the maximum occlusal area of the study group was mm~2,the maximum occlusal force was Ibs and the masticatory efficiency was.Higher than in the reference group,there were statistical differences(P<0.05).The complication rate of the study group was lower than that of the reference group(P<0.05).The incidence of post-repair complications in the study group,which was lower than that in the reference group,with statistical difference(P<0.05).Conclusion The high success rate of metal precrown restoration for deciduous molar proximal caries can effectively improve the occlusal ability of children,help children chew food more efficiently,effectively improve chewing efficiency,and significantly reduce the incidence of complications such as restoration loosening,loss and secondary caries,which has high application value in the treatment of children oral diseases.更多还原
