Estimated savings in U.S. dental expenditures, 1979-89.

The American public saved more than $39 billion (1990 dollars) in dental expenditures from 1979 through 1989 in contrast to the substantial increases in expenditures in other sectors of the U.S. health care system that have pushed the system to the brink of major reform. The dental savings were estimated after controlling for the influence of economic factors, such as changes in prices, insurance, and income, as well as noneconomic factors that could influence the extent of dental disease in the U.S. population. Results of the analysis confirm the importance of both economic and noneconomic factors in the determination of the savings in dental expenditures.
