THE DEMOGRAPHICS OF DR WALKER,GEOFFREY CEPHALOMETRIC COLLECTION

The Bolton-Brush Growth Study Center (BBGSC) at Case Western Reserve U niversity recently acquired the radiographic collection of Geoffrey F. Walker, an orthodontist, anthropologist, and pioneer computer expert. Dr. Walker's culturally diverse collection on more than 1500 persons has added lateral and frontal cephalograms to the Bolton-Brush collect ion. In contrast to the longitudinal Bolton-Brush study, the Walker co llection contains predominantly cross-sectional samples of various tri bes and ethnic groups around the world. A computerized index (similar to the Bolton-Brush index) has been created for efficient access. The addition of this unique collection enhances the BBGSC's ability to ser ve as a resource for orthodontic students, researchers, and practition ers, as well as the physical anthropology community.
