摘　　要：目的比较金属预成冠与3M350通用树脂对乳磨牙邻面龋的修复效果。方法回顾性分析2020年1月-2022年1月间南通市口腔医院收治的89例乳磨牙邻面龋修复患儿的临床资料,根据治疗方式分为观察组(金属预成冠修复治疗,49例49牙)和对照组(3M350通用树脂修复治疗,40例40牙),并比较二者的修复效果、咬合功能、牙周指标、治疗满意度和并发症等。结果观察组的修复成功率(93.88%,46/49)高于对照组(77.50%,31/40),差异有统计学意义(P<0.05)。两组治疗后最大咬合力、咀嚼效率均高于治疗前,且观察组高于对照组,差异有统计学意义(均P<0.05)。两组治疗前的牙周袋深度(PD)、菌斑指数(PLI)、出血指数(BI)比较,差异均无统计学意义(均P>0.05);治疗后,两组PD、PLI、BI均较治疗前降低,且观察组PD、PLI、BI低于对照组(均P<0.05)。观察组治疗总满意度(87.76%,43/49)高于对照组(65.00%,26/40),差异有统计学意义(P<0.05)。观察组并发症总发生率(6.12%,3/49)低于对照组(22.50%,9/40),差异有统计学意义(P<0.05)。结论金属预成冠相较于3M350通用树脂对乳磨牙邻面龋的修复效果更好,并发症发生率更低,可在临床上推广使用。ObjectiveTo compare the effect of metal prefabricated crowns and 3M350 universal resin on the dental caries of deciduous teeth.MethodsRetrospective analysis was performed on the clinical data of 89 children with proximal molar caries restoration admitted to Nantong Stomatological Hospital from January 2020 to January 2022.According to treatment methods,they were divided into observation group(metal prefabricated crowns restoration treatment,49 cases of 49 teeth)and control group(3M350 universal resin restoration treatment,40 cases of 40 teeth).The repair effect,occlusal function,periodontal index,treatment satisfaction and complications were compared.ResultsThe success rate of repair in the observation group(93.88%,46/49)was higher than that in the control group(77.50%,31/40),and the difference was statistically significant(P<0.05).The maximum biting force and masticatory efficiency of the two groups after treatment were higher than those before treatment,and the observation group was higher than the control group,and the difference was statistically significant(all P<0.05).Comparison of periodontal indexes between the experimental and control groups comparison of probing depth(PD),plaque index(PLI),and bleeding index(BI)between the two groups before treatment,the differences were not statistically significant(all P>0.05);after treatment,PD,PLI,and BI were lower in both groups,and lower in the experimental group(all P<0.05).The total satisfaction of the observation group(87.76%,43/49)was higher than that of the control group(65.00%,26/40),and the difference was statistically significant(P<0.05).The incidence of complications in the observation group(6.12%,3/49)was lower than that in the control group(22.50%,9/40),and the difference was statistically significant(P<0.05).ConclusionsCompared with 3M350 general purpose resin,metal prefabricated crowns has better repairing effect and lower complication rate on adjacent caries of deciduous teeth,so it can be widely used in clinic.
