先前的医学和牙科研究记录了小地区、大地区和提供者之间服务率的巨大差异。提供者的实践模式和患者需求的根本差异被认为是这种差异的重要来源。为了控制患者需求的变化，我们根据同质、受过良好教育的中上阶层患者群体计算了华盛顿州 200 名普通牙医的服务率。许多牙科服务的费率存在很大差异。牙医的执业信念和执业特点是比率变化的来源。证据不足以确定每位患者支出最低和最高的牙医是否分别出现治疗不足或过度治疗。然而，在每位患者总支出最低的诊所中，成年患者感知的口腔健康状况低于在每位患者总支出最高的诊所中，这表明在最低支出诊所中可能发生了成年患者治疗不足的情况。
Previous studies in medicine and dentistry document wide variations in service rates across small areas, large regions, and providers. The practice patterns of providers and underlying differences in patient need are thought to be important sources of this variation. To control for variation in patient needs, we calculated service rates of 200 general dentists in Washington state based on a homogeneous, well‐educated, upper‐middle‐class population of patients. Wide variations were found in the rates for many dental services. Dentists' practice beliefs and characteristics of the practice were sources of variation in the rates. The evidence is insufficient to determine whether undertreatment or overtreatment occurred among dentists with the lowest and highest expenditures per patient, respectively. However, the perceived oral health status of adult patients was lower in practices with the lowest total expenditures per patient than in practices with the highest total expenditures per patient, suggesting that undertreatment of adult patients in the lowest‐expenditure practices may have occurred.
