title: Survey of tissue-diagnostic services in United States dental schools, 1953-1980.
abstract: A survey of tissue-diagnostic services in United States dental schools was conducted, covering the services' activities during 1980. This survey was compared to similar surveys done in 1953, 1958, 1969, and 1975. A significant increase in the number of specimens processed has occurred, and there has been a parallel increase in the number of malignant specimens. The percentage of malignancies in relation to total specimens remains stable at 2.0 percent. As could be expected, higher fees are being charged by the schools for processing specimens.
