title: The heat resistance of a data-encoded ceramic microchip identification system.
abstract: Samis introduced the concept of the Dentify system of personal identification. In this system, ceramic microchips embossed with metallic intelligence data are placed in teeth under dental restorations. This paper describes the results of an in vitro study aimed at testing the heat resistance qualities of this identification system when placed in teeth. Teeth were subjected to a temperature of 1,000 degrees C. The results of this study indicate that the ceramic chips and their embossed metallic intelligence data are able to withstand extremely high temperatures. The metallic identifier pins used in this study were less resistant to extreme heat. The significance of these findings is discussed.
