Waiting is the worst part. But I wanted you to know that the Vizilite test, is not really a diagnostic test, and it only help doctors see white lesions, which are not the most dangerous kinds. Also the brush cytology cell collection is not a stand alone test that is definitive, and if it comes back as a a positive, or ambiguous, the doctor is required to send you for a gold standard punch or incisional biopsy to someone like an oral surgeon. Just remember that these things that were done to you are very preliminary, and even a positive finding from them is not a gold standard black and white biopsy result.
The real biopsy is no big deal and nothing to be afraid of. The doc will numb up the area, take a very, very small little piece of it, and send it to a pathologist who will look at the sample under a microscope. THAT pathology finding is the one that you need to be concerned with. So even with what you have been though already, there still will be another step for a definitive answer.
I wish that dentists would just send suspicious things right out for a gold standard biopsy in the first place, instead of putting people though these anxiety creating procedures that do not give you a hard answer to what's going on.
But while you are dealing with this, don't hesitate to come here and vent, and please do not expect the worst outcome. Most things that dentists see in the oral environment turn out to be nothing serious, as we all have little benign abnormalities come and go in our mouths as a routine matter of life.
