Tracey,
I don't really know what dysplaysia is. I tried to look it up but didn't understand the things I found. So I don't know if this will help - some dentists now have a test for oral cancer caused Visilite. They put some stuff in your mouth and shine a special light in. Cancerous and I think pre-cancer cells show up. My dentist is screening all new patients with this now. Too bad I didn't find this dentist until after my first partial glossectomy. If it wasn't the holiday I would call her to find out the relationship with dysplaysia. I hope this can help you.
Happy 4th of July !! Karen
