I just received an image from a doctor that has a red spot on the VELscope image. It is indeed been identified as a bacterial infection, and right where you would suspect one to occur, right around the interdental papilla between two teeth. So I have learned something here about the device. Thank you Jerry for seconding this finding at NYU. By the by, the original posts says : "it was not glowing red, it was white" and that was what threw me off on the thinking about this. I can't count the calls I have gotten from doctors that have the device and are overwhelmed by all the things it finds, most of which are not cancer. This was a problem with the parent company LED, that sold the unit without a proper visual manual on what to look for with decent images of all the possibilities. I finally, in a call with them, told them that I wanted a consulting fee if I was going to take this many hours a week to talk to their accounts about things! These doctors couldn't even determine what a linia alba was..... Jeez was my confidence in general dentistry going down. Needless to say, they are hot on working on a manual that is comprehensive for users....
