摘　　要：目的探究金属预成冠对儿童乳磨牙邻面龋修复的疗效。方法选取2022年1月至2024年1月期间在河南大学第一附属医院接受乳磨牙邻面龋修复治疗的76例患儿作为研究对象,并采用随机数字表法分为对照组(树脂填充修复)与研究组(金属预成冠修复),每组各38例,比较两组修复效果、咀嚼功能、咬合能力及近期并发症发生情况。结果研究组修复效果优良率(94.74%)高于对照组(76.32%),差异有统计学意义(P<0.05)。治疗前,两组咀嚼效率比较,差异无统计学意义(P>0.05);治疗后,两组咀嚼效率均较治疗前升高,且研究组高于对照组,差异有统计学意义(P<0.05)。治疗前,两组最大咬合力与最大咬合面积比较,差异无统计学意义(P>0.05);治疗后,两组最大咬合力与最大咬合面积均较治疗前升高,且研究组高于对照组,差异有统计学意义(P<0.05)。研究组治疗后6个月内并发症发生率(5.26%)低于对照组(23.68%),差异有统计学意义(P<0.05)。结论与树脂填充修复相比,在儿童乳磨牙邻面龋修复中应用金属预成冠的修复效果更佳,可促进患儿咀嚼功能与咬合能力恢复,降低近期相关并发症发生风险,同时具备较高的治疗有效性与安全性。Objective To investigate the efficacy of metal preformed crowns in the restoration of proximal caries in children's primary molars.Methods A total of 76 children who received restoration treatment for proximal caries in primary molars at The First Affiliated Hospital of Henan University from January 2022 to January 2024 were selected.They were randomly divided into a control group(resin filling restoration)and a study group(metal preformed crown restoration),with 38 cases in each group.The restoration effects,chewing function,occlusal ability,and occurrence of recent complications were compared between the two groups.Results The excellent restoration rate in the study group(94.74%)was higher than that in the control group(76.32%),and the difference was statistically significant(P<0.05).Before treatment,there were no significant differences in chewing efficiency between the two groups(P>0.05);after treatment,both groups showed an increase in chewing efficiency compared to before treatment,with the study group having a significantly higher efficiency than the control group(P<0.05).Prior to treatment,there were no significant differences in maximum bite force and maximum occlusal area between the two groups(P>0.05).After treatment,both groups exhibited an increase in maximum bite force and maximum occlusal area compared to before treatment,with the study group demonstrating significantly higher values than the control group(P<0.05).The incidence of complications within 6 months after treatment in the study group(5.26%)was lower than that in the control group(23.68%),with a statistically significant difference(P<0.05).Conclusion Compared to resin filling restoration,the use of metal preformed crowns in the restoration of proximal caries in children's primary molars results in better restoration outcomes,promotes recovery of chewing function and occlusal ability,and reduces the risk of related complications in the short term,while also demonstrating high treatment efficacy and safety.
