摘　　要：目的探讨牙列重度磨损患者的相关临床特征。方法选择牙列重度磨损患者137例,收集其相关临床信息,利用其研究模进行磨损指数评价,应用两独立样本非参数检验进行数据分析。结果 45岁以上组患者的前牙、前磨牙、磨牙磨损指数均显著高于45岁以下组(P<0.01)。男性患者的前牙、前磨牙、磨牙磨损指数均显著高于女性患者(P<0.01)。有磨牙症史患者的前牙、前磨牙、磨牙区的磨损指数高于无磨牙症史患者(P<0.01)。结论重度磨损患者的牙齿磨损程度与年龄、性别及有无磨牙症史关系密切。Objective To investigate the clinical characteristics of severe tooth abrasion,and to analyze the clinical data of patients with severe tooth abrasion.Methods One hundred and thirty seven patients with severe tooth abrasion were involved in the present study.The related clinical data were collected.Tooth wear index（TWI） of every tooth in plaster mould was assessed.Nonparametric test was used to analyze the data.Results The TWI of anterior teeth,premolars and molars in patients older than 45 years,were higher than those in patients younger than 45 years.The TWI of anterior teeth,premolars and molars in male patients,were higher than those in female ones.The TWI of anterior teeth,premolars and molars in patients with bruxism,were higher than patients without bruxism.Conclusion The degree of tooth abrasion in patients with severe tooth abrasion,is related to age,sex and bruxism.
