I don't have an answer for you I'm afraid BF, and I know that Bryanna hasn't posted in a little while, but it still might help if you were to copy this post over to the Dental Forum.

Hopefully Bryanna will be back soon, or maybe some-one else might have the answers that you seek. There's no promises of course, but it certainly wouldn't hurt to post your question over there just the same.

Here's the direct link to the Dental Forum incase you decide to give it a try....... http://neurotalk.psychcentral.com/forum89.html
