摘　　要：目的 :调查老年人唾液流速、pH值及缓冲力的变化与牙齿颈部楔状缺损的关系。 方法 :选 84名老年人 ,采用Smith牙齿磨损指数分度检查全口牙齿颈楔状缺损 ,并据缺损程度分组 ;检测新鲜刺激唾液的流速、pH值及缓冲力。结果 :牙齿颈部楔状缺损程度不同组间与唾液流速、pH值及缓冲无差异。 结论 :牙颈部楔状缺损与唾液流速、pH及缓冲力无明显关系。Objective:The aim of the study was to investigate the relation of some saliva factors to wedge-shape defects of tooth in the elderly.Methods:The material comprised 84 subjects,whose wedge-shape defects of tooth were evaluated with Smith’ tooth wear index.According to the TWI,the subjects were divided into mild and severe group.Saliva samples in stimuli wax from subjects were measured.Results:No different was found between groups in salivary flow rate,pH and buffer capacity.Conclusion:The salivary pH and buffer capacity has no significant relation to wedge-shape defects of tooth.
