  11. 11.   Advancement in the knowledge of dental materials and their manipulation began in 1919. during that year the U.S. Army requested the National Bureau of Standards (now known as the National Institute of Standards and Technology [NIST]) to set up specifications) For dental amalgam which will be used for federal services 9 November 2013 11
  12. 12.    This research was done under the leadership of Wilmer Souder, and an excellent report on this study was published in 1920 The contents of the Souder report was received enthusiastically by the dental profession Similar testing data were then requested for other dental materials 9 November 2013 12
  13. 13.     There were no funds with the government A fellowship was created and supported by the Weinstein Research Laboratories Sponsors have to pay the expenditure Dr sauder was the supervisor of the committee 9 November 2013 13
  14. 14.    Several research associates investigated the properties of dental wrought gold materials, casting gold alloys, and accessory casting materials This phase of the work resulted in the publication of an extensive and valuable research report In 1928 Researchers such as Wilmer Soudr, George C Paflenbargel and William T Sweeney will undoubtedly be remembered historically as the pioneers 9 November 2013 14
