Survey of tissue diagnostic services in United States dental schools, 1953-1975.
A survey of tissue diagnostic services in United States dental schools was conducted, covering the services' activities during 1975. This survey was compared to similar surveys made in 1953, 1958, and 1969. Most significantly, many more biopsies are being processed, with a great increase in the number of malignant specimens. As could be expected, higher fees are being charged by the schools for processing specimens.
