As a public health agency, the Indian Health Service (IHS) must plan f
or the needs of the entire American Indian and Alaskan Native (AI/AN)
population and distribute resources as equitably as possible. To facil
itate this process, the IHS has developed a manpower planning model to
provide for the distribution of dental providers based upon the denta
l needs of the AI/AN population and within the limits of annual approp
riations of funds. This paper briefly describes the original IHS Denta
l Program manpower planning model and the development of modifications
over time. The need-based approach to manpower planning developed by
the IHS Dental Program has exhibited utility and flexibility over time
. It allows a determination of clinic size (number of operatories) and
dental staffing requirements, and may be generalizable to other publi
c health programs if an accurate assessment of utilization rate and tr
eatment need can be made for the defined population. Nonetheless, the
availability of resources in public programs is subject to the comprom
ises inherent in the political process; thus, the use of a manpower pl
anning model alone may not be sufficient to ensure the equitable distr
ibution of dental resources and dental providers.
