[FTIR microspectroscopic investigation on the stained and unstained histotomic section of oral tissues].

In this paper, stained and unstained samples of oral tissues have been investigated using FT-microspectroscopy. The experimental results demonstrated that staining did not influence the characteristic features of the FTIR spectra of the oral tissues, thereby providing abundant opportunity of further understanding of the structural-spectral relationship of normal and malignant tissues.
