摘要
目的比较金属预成冠与树脂充填在乳磨牙邻面龋治疗中的效果。方法收集2018年1月—2019年4月收治乳磨牙邻面龋损患儿225例,其中龈上邻面龋124例,龈下邻面龋101例,分别采用金属预成冠和树脂充填两种修复方式。比较两组治疗0.5、1、2 a后的效果。另收集新鲜拔除的乳磨牙40颗,其中金属预成冠修复组和树脂充填组各20颗,将其浸泡于碱性品红溶液中,观察其微渗漏情况。结果龈上邻面龋中,治疗0.5 a后,金属预成冠组修复成功率较树脂充填组高,但差别无统计学意义(P>0.05);治疗1、2 a后,金属预成冠组修复成功率(91.80%、86.89%)较树脂充填组(79.36%、66.67%)高,差别有统计学意义(P<0.05)。龈下邻面龋中,治疗0.5 a后金属预成冠组修复成功率较树脂充填组高,差别无统计学意义(P>0.05);治疗1、2 a后,金属预成冠组修复成功率(86.54%、80.77%)较树脂充填组(69.39%、59.18%)高,差别有统计学意义(P<0.05)。与树脂充填比较,金属预成冠修复后微渗漏情况较好(P<0.05)。结论金属预成冠修复乳磨牙邻面龋(特别是龈下邻面龋)效果较树脂充填更好,且微渗漏更小,效果更佳。
Objective To compare the effect of stainless steel crown restoration and resin filling in the treatment of approximal surface caries of deciduous molars.Methods The total of 225 children with approximal surface caries of deciduous molars were treated from January 2018 to April 2019.Stainless steel crown and resin fillings were used respectively.The two groups were compared after 6 months,1 year and 2 years of treatment.Among them,124 cases were supragingival approximal surface caries,101 cases were subgingival approximal surface caries.In addition,40 deciduous molars were extracted.Among them,20 were in the stainless steel crown group and 20 were in the resin filling group.The molars were soaked in alkaline fuchsin solution and their microleakage were observed.Results In the cases of supragingival approximal surface caries,the success rate of stainless steel crown group was higher than that of the resin filling group after 6 months of treatment,but the difference was not statistically significant(P>0.05).The repair success rate of the stainless steel crown group(91.80%,86.89%)was higher than that of the resin filling group(79.36%,66.67%)after 1 year,2 years of treatment,the difference was statistically significant(P<0.05).In the cases of subgingival approximal surface caries,the success rate of the stainless steel crown group was higher than that of the resin filling group after 6 months of treatment,but the difference was not statistically significant(P>0.05).The repair success rate of the stainless steel crown group(86.54%,80.77%)was higher than that of the resin filling group(69.39%,59.18%)after 1 year,2 years of treatment,the difference was statistically significant(P<0.05).The results of some laboratory experiments showed that compared with resin filling,the microleakage after stainless steel crown repair was generally better(P<0.05).Conclusions Compared with resin filling,the stainless steel crown is more effective in repairing deciduous molar adjacent caries,especially subgingival approximal surface caries
