  • Title: The histochemical nature of homogeneous amorphous materials in odontogenic epithelial tumors.
    Author: Mori M, Makino M, Imai K.
    Journal: J Oral Surg; 1980 Feb; 38(2):96-102. PubMed ID: 6153217.
    Abstract:
    The homogeneous acellular materials in the adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, and calcifying odontogenic cyst were examined histochemically for specific staining of amino acids and protein groups. These materials gave a positive reaction for periodic acid-Sciff (PAS), alloxan-Schiff, and dinitrofluorobenzene-H-acid and low reaction for alcian blue, dimethylaminobenzaldehyde (method for tryptophan) and the Morel-Sisley diazotization method. They appear to have approximately the same composition as enamel matrix and are not amyloid in nature. The materials may be synthesized products from neoplastic epithelium that may originate from enamel organs.
