Abstract

The present study deals with the in vivo measurement of auto-fluorescence from different anatomical sites of oral cavities of healthy volunteers, using a homebuilt Laser Induced Fluorescence (LIF) Spectroscopy setup. Excitation wave length of 325 nm from a He-Cd laser was used as the source. From the 7 anatomical sites (say buccal mucosa, tongue, palate etc) of each oral cavity of 113 subjects, 1266 fluorescence spectra were recorded. The spectra were analysed using Principal Component Analysis (PCA) to see the correlation between different sites.
