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.
在过去五年中，各类专业人员的广告限制已逐渐放宽。1976年进行了一项研究，并于1981年重复进行，以比较牙医对一般广告、收费广告、服务广告以及广告对各种公共问题的影响的态度变化。在此期间，牙医对广告的态度发生了显著变化，总体上变得更加积极。
