title: Update on imbalanced distribution of endodontists: 1995-2006.
abstract: BACKGROUND
  Past studies on the number of endodontists in the United States indicated an imbalanced distribution of private practice endodontic practitioners in most regions, states, counties, and zip code areas of the country. The availability of more recent studies by the American Dental Association (ADA) provides an opportunity to follow up on these previous studies.
  
  
  METHODS
  The 2006 and past ADA surveys on the Distribution of Dentists in the United States, Advanced Dental Education, and Dental Practice were used to evaluate the number of graduates from advanced education programs in endodontics, the changing number and distribution of endodontists, full-time and part-time work patterns, and the income of private practicing endodontists.
  
  
  RESULTS
  A gradual increase in the number of graduates from advanced education programs in endodontics is reflected in a continuing increase in the overall number of private practicing endodontists, but with ongoing differences in endodontists-to-population ratios at the regional and state levels.
  
  
  CONCLUSIONS
  The findings follow previous study results confirming the increasing numbers of endodontists and continuing differences in the endodontists-to-population ratios at both the regional and state levels. Concerns about the distribution of endodontists in the future need to be considered in terms of evolving dental disease patterns, changing demands for services, evolving third-party mechanisms, and the increased number of female practitioners (with fewer reported working hours than their male counterparts).
