(jointly sponsored by NIST Standards Alumni Association)

The Paffenbarger Research Center (PRC) has a distinguished 80-year history. It began as a collaborative effort between NBS and the American Dental Association to develop specifications and test methods for dental materials used by the U.S. War Department. Developed, too, were instruments and materials used in the daily practice of dentistry that have had an unparalleled impact on oral care. These inventions include the panoramic x-ray machine, the high speed handpiece, resin composite filling materials, and dental bonding systems. The PRC is a classic example of NIST’s goal to include private organizations in research of mutual interest. The presentation will provide a historical perspective of the ADA/NIST collaboration and highlight 80 years of accomplishments.
