I am a dentistry student from the University of Manitoba, Canada. I am currently involved in a research about using dental materials to identify human corpse. The goal of the project is to construct a database of different brands of materials, which samples from crime scenes can be matched against. I am hoping to get intraoral materials from different countries to aid identify the nationalities of the deceased. The result will be used to help solve future cases. If dentists from around the world can donate some sample sealant, crowns, cement, restoration material, resin, amalgam, orthodontic wire, orthodontic brackets, implant...etc for this project, it would be a great assistance to the project. Please PM or email [Only registered and activated users can see links. ] if you are interested in donating dental materials. Thank you!
