Survey of tissue diagnostic services in U.S. dental schools - 1990.

Tissue diagnostic services in U.S. dental schools were surveyed to determine activities during 1990. Results were compared with those of similar surveys conducted in 1953, 1958, 1969, 1975, 1980, and 1985. The information gathered from this survey reveals a progressive growth and development of tissue diagnostic services. This is seen not only in the increased numbers of biopsy accessions, which increased by 37% since the last survey, but is also reflected in the diversity of services now offered by oral pathologists.
