Patients diagnosed with early stage oral cancer are usually examined by their doctor for suspicious areas in the mouth and throat area. A study was conducted that tested two diagnostic aids in evaluating lesions in the oral cavity.

Chemiluminescent light, or brand name Vizilite and toluidine blue, pharmaceutical grade dye, were used in addition to the conventional, visual and manual observations of the patient.

“By combining conventional techniques with more modern techniques, we were able to better diagnose and determine the best options for patients with oral cancer,” said J.B. Epstein, lead author of the study and Professor at the University of Illinois at Chicago.
