A longitudinal analysis of dentists' attitudes toward advertising their fees and services.

Over the past five years restrictions on advertising by various categories of professionals have gradually been reduced. A study was conducted in 1976 and replicated in 1981 to provide a basis for comparison of the change in attitudes by dentists toward advertising in general, advertising of fees, advertising of services, and the effect of advertising on various public issues. The attitudes of dentists toward advertising changed significantly during this period, generally becoming more positive.
