Trend analysis of dental expenditures by selected dentist and practice characteristics, 1985-1995.

Using the reported gross billings from the annual ADA "Survey of Dental Practice," the authors estimated the total national dental expenditures according to various dentist characteristics for the period of 1985-1995. These selected characteristics are specialty, office time, number of dentists in the practice, sex, length of experience and U.S. region. As government agencies do not report dental expenditures by such dentist characteristics, the data presented in this article may be the first of their kind to be estimated and published.
