Autofluorescence Diagnosis for Oral Squamous Cell Carcinoma

Abstract

We made spectral analysis in patients with oral SCC using a UV- excited autofluorescence photographic apparatus and found that there were a bimodal peak at 630 and 680nm at the excitation wavelength of 410nm; we found a clear difference from the autofluorescence of the oral cavity of normal human subjects and oral benign diseases. We considered that fluorescence diagnosis of oral SCC would be possible by means of this method.
