金属预成冠修复大面积龋损儿童乳磨牙的临床观察

Clinical observation of metal prefabricated crown in repairing deciduous molars of children with large area caries

目的:研究观察金属预成冠修复大面积龋损儿童乳磨牙的临床效果。方法:2015年1月-2018年1月收治乳磨牙大面积龋损患儿100例,随机分为两组,各50例。对照组给予单纯固化树脂修复治疗;观察组给予金属预成冠修复治疗。比较两组治疗效果。结果:观察组术后6个月及12个月修复成功率显著优于对照组,差异有统计学意义(P<0.05)。结论:金属预成冠修复大面积龋损儿童乳磨牙的临床效果显著,有效改善了咬合关系,使修复率得以提高,且牙龈状态无不良反应。

Objective:To observe the clinical effect of metal prefabricated crown in repairing deciduous molars with large area caries in children.Methods:From January 2015 to January 2018,100 children with extensive caries of deciduous molars were selected,they were randomly divided into the two groups with 50 cases in each group.The control group was treated with solidified resin.The observation group was treated with metal prefabricated crown repair.The therapeutic effects of the two groups were compared.Results:The success rate of repair in the observation group was significantly better than that in the control group at 6 and 12 months after operation,the differences were statistically significant(P<0.05).Conclusion:The clinical effect of metal prefabricated crown in repairing deciduous molars with large area caries is significant,the occlusal relationship is effectively improved,the repair rate is increased,and there is no adverse reaction in gingival state.
