EPIMIСROSCOPIC AVILABLE ENAMEL-DENTIN BORDER AND INTERGLOBULAR DENTIN OF MOLARS AND PREMOLARS IN THE AGE ASPECT

Abstract

In severe physiological abrasion on enamel dried histochemical stained thin sections along the enamel-dentin bor-der, as well as directly in the dentin canals appear. Data feeds into contact with damaged dentinal tubules and dentin interglobular, and their formation is due to the change textury hydroxyapatite crystallites. A more detailed study of fluorescent epimicroskopic enamel-dentine limits found in sections of the equator and neck crown with little erasing enamel in unprizmal part of it are more shallow light channels. They anastomozing to-gether forming structure to which intertwined blades, which in turn contain basophilic substance and penetrate the en-tire thickness of the enamel in its physiological abrasion. During the subsequent epimicroskopical research found that enamel-dentinal canals fibrous layer Korf and some of them ending near interglobular dentin. It should be noted that such an arrangement channels near interglobular den-tin is found in the teeth of older people with severe physiological wear of enamel, especially in the areas of tubercles.
