Well. I was reviewing material for a course that I am giving Wed 12/5/07 at the Mass Dental Society Headquarters and I found that I have an old blog floating on the Internet. It is drpaulf.blogspot.com . This one is drpauldentaltech.blogspot.com. I wonder which one will work better- I may stick with the drpaulf- certainly easier, although it doesn't hint at the content. Maybe I will have the class decide Wednesday.
