Jerry Bouquot explains the different degrees of severity of dysplasia and its implications in oral precancer. He also presents new technologies and gadgets for better identifying this disease. Among such tools are the Toluidine blue test, the brush biopsy and the ViziLite technique, as well as the fluorescence test.

For each method, he provides a review of the correct steps for its implementation, along with the up and downsides implied, in addition to the precise area to test, in an effort of obtaining the best results. This lecture is enriched with images that show how each procedure would look like on a real life patient, and in the particular case of the fluorescence test, images of different types of oral dysplasia are analyzed.
