北京某大学学生志愿者牙侵蚀症患病情况及相关因素调查

目的 对北京某大学学生牙侵蚀症（又称牙酸蚀症）患病情况进行初步调研，分析其相关因素。方法对179名北京某大学在校学生志愿者，采用问卷方式调查牙侵蚀症相关因素，并用van Rijkom改良标准进行临床评估。结果该组人群牙侵蚀症患病率为45．8％，均为牙釉质病损。好发牙面为前牙唇面。牙侵蚀症的发生与碳酸饮料、果汁、冲饮饮料和香蕉等酸性饮食因素相关。结论应对我国青年人群牙侵蚀患病情况加以重视，加强口腔卫生教育和饮食指导。

Pilot study of dental erosion and associated factors in university student volunteers

Objective To investigate dental erosion and associated etiologic factors among students from one university. Methods A total of 179 student volunteers from one university were examined clinically for their dental erosion. Each was required to complete a questionnaire regarding potentially associated etiologic factors. A modified criteria was used to grade the severity of dental erosion. Results The prevalence of dental erosion of this group was 45.8% , mostly in enamel. Facial surfaces of anterior teeth were most vulnerable to erosion. Statistic analysis indicated that acidic diets, such as carbonated drink, fruit juice, fruit drink and banana were risk factors to dental erosion. Conclusions The findings strongly suggest that much attention should be given to dental erosion which was probably associated with acidic diet.
