This article assesses the impact of dentist remuneration on the incidence of potentially harmful dental X-rays. We use unique panel data which provide details of 1.3 million treatment claims by Scottish NHS dentists made between 1998 and 2007. Controlling for unobserved heterogeneity of both patients and dentists we estimate a series of fixed-effects models that are informed by a theoretical model of X-ray delivery and identify the effects on dental X-raying of dentists moving from a fixed salary to fee-for-service and patients moving from co-payment to exemption. We establish that there are significant increases in X-rays when dentists receive fee-for-service rather than salary payments and when patients are made exempt from payment.
本文评估了牙医薪酬对潜在有害牙科 X 光片照射发生率的影响。我们使用了独特的面板数据，这些数据提供了 1998 年至 2007 年间苏格兰国民保健制度牙医进行的 130 万次治疗索赔的详细信息。通过控制患者和牙医的未观察到的异质性，我们估计了一系列固定效应模型，这些模型是根据 X 光片投递的理论模型得出的，并确定了牙医从固定工资转向按服务收费以及患者从共同支付转向豁免对牙科 X 光检查的影响。我们发现，当牙医接受按服务收费而不是工资支付，以及当患者被豁免支付时，X 光照射显著增加。
