A dental work force study

Background. Many segments of the population experience one or more barriers to accessing quality oral health care, including availability of licensed dentists. The purpose of the authors’ study was to analyze the availability of dentists in Mississippi by county over four decades to determine the geographic distribution of dentists, shifts in their distribution over time and how this distribution relates to population demographics.

Methods. Dentist-to-population ratios were determined by county from 1970 through 2000. The authors analyzed these data using standardized z scores and geographic information systems (GIS) technology. Results are presented graphically and geographically.

Results. Results showed that 55 counties were designated as dental health professional shortage areas in 1970, 51 counties in 1980, 30 in 1990 and 40 in 2000. Counties that have a more favorable ratio of providers to population were determined, indicating areas in which dentists are more likely to practice.

Conclusions. Many geographic areas in Mississippi remain underserved. Identifying these areas is a critical first step when addressing the current state of Mississippi’s dental work force. This type of information is useful for decision making as well as responding to the population’s oral health care needs.

Practice Implications. Results of this study can assist current and future practicing dentists, dental school administrators and policy-makers in making informed decisions for determining suitable practice locations, dental school admissions criteria and areas to target for public health initiatives. This model also is useful for studying work force disparities in other health care professions.
