There already exists a body of literature on the conduct of classical epidemiological studies. However, guidelines tend towards detailing how such studies should be conducted and may not prepare the reader for the less-than-perfect scenarios that will inevitably be encountered. The Dental Health Services Research Unit in Dundee has been involved in longitudinal studies of dental treatment and dental health since its inception in 1979. The problems encountered in this research are considered under the headings of mounting the studies, samples, data collection, external changes, internal changes, dissemination and curtailment. It is hoped that a description of the often unpredictable problems associated with a particular set of studies will provide an insight which may assist others embarking on analogous projects in health services research.
关于开展经典流行病学研究已有大量文献。然而，指南往往倾向于详细说明此类研究应如何进行，可能无法让读者为不可避免会遇到的不尽完美的情况做好准备。邓迪的牙科保健服务研究单位自1979年成立以来一直参与牙科治疗和牙齿健康的纵向研究。本研究中遇到的问题在研究开展、样本、数据收集、外部变化、内部变化、传播和缩减等标题下进行了探讨。希望对与特定一组研究相关的常常不可预测的问题的描述能提供一种见解，有助于其他从事卫生服务研究类似项目的人。
