Роль углеводно-белковых биополимеров и гиалуроновой кислоты в формировании резистентности твердых тканей зуба от патологических процессов кариозного и некариозного генеза

Abstract

At the series of histochemical studies hypothesis of existence of a "cationic protein" in human tooth structure and set of its amino acids components and hyaluronic acid has been checked. Taking into account histogenesis and cytogeny of tooth structure and the earlier results received from the epidermis and multilayer partly keratinous epithelium of the oral mucosa, special studies had been created, based on the original equipment preparation of paraffin sections, and thin sections of the whole teeth and modified histochemical identification technology of carbohydrate-protein biopolymers in hard dental tissues. Histological slides are prepared from extracted for orthodontic indications teeth. Sectioned and examined thin sections of teeth has investigated in transmitted light for issues related to topochemistry of carbohydrate-protein biopolymers and hyaluronic acid concerning the distribution in structures of enamel, dentin, predentin, cellular and acellular cement. Identified carbohydrate-protein biopolymers and substances of protein nature objectively fill inter prismatic enamel areas, dentin tubules and their walls, localized in the cement structure of tooth and its soft tissues forming a physiologi-cal barrier to microorganisms and their metabolic products as in the demineralizing processes as for the mechan-ical interventions during the vital activity and medical interventions.
