Eating disorders are often associated with regurgitation of gastric contents into the mouth and dental erosion. In this study the dental status was evaluated in bulimic patients. Thirty-five bulimics, diagnosed in the Outpatient Departments of Psychiatry and Adolescent Psychiatry of the University Central Hospital in Helsinki, and 105 controls matched for age, sex, and educational level were examined clinically, and the factors associated with dental erosion and caries were evaluated in an interview. Severe dental erosion and dental caries were significantly commoner among bulimics than controls. Bulimics commonly had a low salivary flow rate, but other apparent risk factors of dental erosion did not differ from those of controls. A feeling of dry mouth was commoner among bulimics than controls, and bulimics had an increased tooth sensitivity to cold and touch. More should be done to protect teeth from dental erosion among bulimics, because loss of tooth tissue remains even if the eating disorder disappears.
饮食失调常常与胃内容物反流至口腔以及牙齿侵蚀有关。在本研究中，对贪食症患者的牙齿状况进行了评估。选取了35名在赫尔辛基大学中心医院精神科和青少年精神科门诊确诊的贪食症患者，以及105名年龄、性别和教育水平相匹配的对照者进行临床检查，并通过访谈评估与牙齿侵蚀和龋齿相关的因素。贪食症患者中严重牙齿侵蚀和龋齿的发生率明显高于对照组。贪食症患者通常唾液流速较低，但其他明显的牙齿侵蚀风险因素与对照组并无差异。贪食症患者比对照组更常出现口干的感觉，并且贪食症患者对冷和触摸的牙齿敏感度增加。对于贪食症患者，应采取更多措施保护牙齿免受侵蚀，因为即使饮食失调消失，牙齿组织的损失依然存在。
