American Association of Orthodontics Foundation Authorizes Second Stage of Craniofacial Growth Legacy Collection Project

June  21, 2011

A groundbreaking project known as the Craniofacial Growth Legacy Collection has been authorized by the American Association of Orthodontics Foundation (AAOF) to move forward into its second and final stage.

The Craniofacial Growth Legacy Collection, which is led in part by two faculty members at the Arthur A. Dugoni School of Dentistry, digitizes and preserves various craniofacial research collections.

The project is centered in the Craniofacial Research Instrumentation Laboratory (CRIL) at the Dugoni School of Dentistry. It is intended to preserve, digitize, and make available to the public irreplaceable materials from nine major craniofacial research collections started through the US and Canada.

The project's second stage will add to the existing collection of longitudinal X-ray images of untreated patients as they matured. In this stage, a team will compile and add records from other labs and academic institutions from throughout the United States.

The second stage of the Craniofacial Growth Legacy Collection project is funded by an $800,000 grant from AAOF. This is the final part of a $1,000,000 multi-year grant awarded by AAOF. The money will primarily be used to expand the Craniofacial Growth Legacy Collection website and fund participating universities to develop their record collections.

The Dugoni School of Dentistry's unique involvement with this project comes from the work of two professors in the school's Orthodontic Department, Drs. Sheldon Baumrind and Hee So Oh.

Baumrind is a professor in the Dugoni School of Dentistry's Orthodontic Department and serves as director of CRIL. He is also the principal investigator for the AAOF Craniofacial Growth Legacy Collection project. Oh is an associate professor in the Orthodontic Department and was recently appointed as CRIL's associate director.

 Baumrind and Oh will collaborate with colleagues from other institutions throughout the United States including Case Western University, Forsyth Institute, Oregon Health and Sciences University, University of Iowa, University of Michigan, University of Oklahoma, University of the Pacific, University of Toronto and Wright State University to compile, digitize, preserve, and make the records available online for public use.

 Once archived, the research collections are available for viewing by clinicians, craniofacial investigators, students and interested members of the public. Researchers can access various types of X-rays, growth information, models and other information from untreated patients of various ages and backgrounds.

The records consist largely of standardized X-ray images of the heads and faces of growing children taken annually between the ages of seven and 20 years. Longitudinal growth records of this kind can no longer be obtained, making the current collection literally irreplaceable. Information from these very sets of records has already provided a substantial portion of science exists knowledge of the differing patterns of craniofacial growth that characterize human development from childhood to physical maturity.

These records, which span from the 1920s to the 1970s, serve as a unique control for the field of orthodontics and clearly display what a patient's craniofacial state was without orthodontic intervention. Access to the records is available on the web at

"Congratulations to all who have supported and contributed to this unique project," said Dr. Patrick J. Ferrillo, Jr. dean of the Dugoni School of Dentistry. "I look forward to watching the Craniofacial Legacy Collection continue to grow and become an even more valuable resource for dental professionals and researchers around the world."

"Dr. Baumrind is one of the world's leading experts on clinical orthodontic study design and measurement," added Dr. Robert Boyd, Chair of the Department of Orthodontics at the Dugoni School of Dentistry. "His lifetime work consists of many classical studies on cephalometrics and orthodontic treatment outcomes. He has made a huge contribution to the science of orthodontics."
