This prospective study investigated the influence of professional training and method of payment on how dental practitioners planned extraction of impacted third molars. The subjects were four groups of dental practitioners in metropolitan Chicago: 1) general dentists in traditional fee-for-service practice; 2) general dentists who were members of a preferred provider organization; 3) general dentists who were members of an Independent Practice Association model of a capitation system; and 4) oral and maxillofacial surgeons, all of whom were in fee-for-service practice. A carefully selected and trained professional actress, in good health, with four unerupted, impacted, and asymptomatic third molars, brought her recently taken full mouth periapical and panoramic radiographs to randomly selected dentists for a consultation. The number of planned extractions (no treatment was ever done) was compared. Data showed that oral and maxillofacial surgeons suggested significantly more extractions than capitation dentists and the average of all general dentists, combined.
这项前瞻性研究调查了专业培训和支付方式对牙科医生计划拔除阻生第三磨牙的影响。研究对象是芝加哥大都市地区的四组牙科医生：1）采用传统按服务收费方式的普通牙医；2）优先提供者组织的成员普通牙医；3）按人头付费系统的独立执业协会模式的成员普通牙医；4）口腔颌面外科医生，他们均采用按服务收费方式。一名精心挑选并经过培训、身体健康、有四颗未萌出、阻生且无症状第三磨牙的职业女演员，带着她最近拍摄的全口根尖片和全景片随机找牙医咨询。比较了计划拔牙的数量（从未进行过治疗）。数据显示，口腔颌面外科医生建议拔除的牙齿数量明显多于按人头付费的牙医以及所有普通牙医的平均数量之和。
