With the support of the AAO Foundation,nine of the 11 known collections of longitudinal craniofacial growthrecords in the United States and Canada have been joined together tocreate a Web siteand database to give clinicians, craniofacial researchers, students ofhuman growth, and members of the public better access to thesematerials.

The collections represent the work of hundreds of investigators,covering more than 75 years of research. Taken together, the collectionsoffer an extensive longitudinal record of craniofacial developmentamong children who did not receive orthodontic treatment.

Documentation available in the collections includes various skullx-ray images, hand-wrist films, dental radiographs, facial photographs,and study casts. Written records on the physical and educationaldevelopment of the children of various ethnicities and growth patternsalso are available.
