Evolving trends in size and structure of group dental practices in the United States.

In this study, the authors examined recent trends in the growth of dental establishments and dental firms, including geographic location. In this article, they also present information about the demographic characteristics of dentists who work in a dental practice that is part of a larger company that delivers dental care in multiple locations. The number of dental establishments (single locations) and the average size of these establishments grew from 1992 to 2007. Large multi-unit dental firms grew in terms of number of establishments and the percentage of total receipts. Large multi-unit dental firms represent a small but growing segment of the dental market. Dentists less than thirty-five years old were most likely to work in a practice that was part of a larger company, and females were more likely than males to work in such a setting. The percentage of dentists working in these settings was also found to vary by region and state. The authors present a typology of dental group practice and suggest that future research should take into account the differences so that appropriate conclusions can be drawn and generalizations across categories are not made.
