hi Rachie,

Check out this site, for Consumers for Dental Choice, they have some good articles that might help with your paper.

Also, try doing a Google for the research and work of Bernie Windham -- he's compiled lots of information. Don't know if it will be specific enough for your needs, but it's worth reading anyway. Here's a link to one of his articles:

Good luck.
