International dental materials

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 email tsycheung@xxxxxxxxx if
you are interested in donating dental materials. Thank you!
