The VELscope® Vx system uses enhanced tissue fluorescence visualization technology to directly view the oral mucosa much more effectively than can be achieved with the unassisted eye.

This technology, which is backed by over $50 million in research funded by the NIH and other respected organizations, has been in place in the medical field for years. VELscope® represents the first and most widely used oral application of this technology and has had numerous papers and case studies published supporting its ability to help discover oral mucosal abnormalities, including oral cancer and pre-cancer.
