摘要/Abstract

摘要： 【摘要】目的探讨两种修复方式对乳磨牙大面积缺损的咀嚼效率的影响。方法选择乳磨牙大面积缺损的患儿60例,将其随机分成A、B两组。A组选用复合树脂修复，B组选用金属预成冠修复。采用X50测量法，比较两组患儿6个月、12个月后的咀嚼效率。结果 A、B两组6个月后的咀嚼效率无统计学意义（P＞0.05）；B组12 个月月后的咀嚼效率均明显高于A组（P＜0.05）。结论大面积缺损的乳磨牙经金属预成冠修复后咀嚼效率显著，高于复合树脂修复，且能被患儿及家长接受，在临床值得广泛推广。

Abstract: [abstract] Objective To investigate the effect of two kinds of restoration methods on masticatory efficiency of deciduous molars with large area defect. Methods 60 children with large area defect of deciduous molars were randomly divided into A and B groups. Group A was repaired with composite resin and group B was repaired with metal prefabricated crowns. The masticatory efficiency of the two groups after 6 months and 12 months was compared by X50 method. Results There was no significant difference in masticatory efficiency between group A and group B after 6 months (P > 0.05). The masticatory efficiency of group B after 12 months was significantly higher than that of group A (P < 0.05). Conclusion The masticatory efficiency of primary molars with large area defect restored by metal prefabricated crowns is remarkable, which is higher than that restored by composite resin, and can be accepted by children and parents. It is worth popularizing widely in clinic.
