Good Evening Jeff Hornaevk - New to the forum as of this evening. I also have dysplasia for the past two years. Two biopsies within the first year of diagnosis. First one in the buccal mucosa/vestibule and floor of mouth. Second biopsy left lateral of tongue. To respond of dysplasia returning I agree with Christine's comments. Mine are very visible and have never disappeared. From April 2016 I have been closely monitored by a pathologist by exams and taking photographs. Today I had an appointment with a new dentist who absolutely felt being with a pathologist was the correct route for monitoring. He also examined my oral cavity and could see the lesions. Best of Luck to you.
