摘要
楔状缺损是非龋性疾病中的常见病,是牙齿唇、颊面牙颈部硬组织发生慢性消耗所致的缺损。其缺损由两个平面相交而成,边缘整齐,表面坚硬光滑,一般均为牙体硬组织本色,有时可有不同程度的着色,好发生于前磨牙,尤其是第一前磨牙,随着年龄增长,楔状缺损有增加的趋势,年龄愈大,楔状缺损愈严重。近年来国内外学者对于楔状缺损的病因学研究更加深入、临床治疗进展的报道也越来越多,本文对楔状缺损的病因、流行情况及治疗进展进行综述。
Wedge shaped defects is common non-caries dental disease,which caused by chronic consumption of hard tissue close to lips,buccal and neck.The defects formed by the intersection of two planes,with neatly edge,hard and smooth surface;the defects general had the same color of dental hard tissue,but sometimes could also be with other different colors;the defects were commonly found in the premolars,especially in the first premolar;wedge-shaped defect increase with age growth.In recent years,there were more and more studies focusing on the etiology and clinical progress.Here,we summarized the risk factors,prevalence and clinical treatment for wedge shaped defects.
