This investigation was concerned with determining the optimum team mix for a dental practice utilizing expanded duty dental assistants (EDDAs). A live, surrogate practice provided the basis for a computer-simulated private practice in which one dentist worked with various combinations of chairside assistants and expanded duty auxiliaries. This "composite dentist" was of average speed as an operator, functioning under conditions of an external quality control mechanism. Results indicated that the optimum team size, from the standpoint of both productivity and economic considerations, involved one dentist, one EDDA, and two assistants, as compared with the control team of one dentist and two assistants. Experimental teams involving two EDDA's, studied both with and without chairside assistants, were counterproductive from a financial standpoint. Various factors influencing team size are discussed, but dentist operator speed emerges as a major determinant of optimum team mix.
本研究旨在确定配备扩展职责牙科助理（EDDA）的牙科诊所的最佳团队组合。一个实际的替代诊所为计算机模拟私人诊所提供了基础，在该模拟诊所中，一名牙医与不同组合的椅旁助理和扩展职责辅助人员合作。这位“综合牙医”作为操作者速度处于平均水平，在外部质量控制机制的条件下工作。结果表明，从生产力和经济考虑的角度来看，最佳团队规模是一名牙医、一名EDDA和两名助理，而对照组是一名牙医和两名助理。从财务角度来看，涉及两名EDDA且有或没有椅旁助理的实验团队产生了适得其反的效果。文中讨论了影响团队规模的各种因素，但牙医操作者的速度成为最佳团队组合的主要决定因素。
