“…Кроме микротрещин на макропрепарате мы видим различную толщину эмали в зависимости от группы зубов и их поверхности [14]. К примеру, экватор временных зубов более выражен, но это придает зубу более тонкую «талию», в пришеечной области слой эмали незначительный, и граница эмали и цемента тоже неровная и хрупкая, поэтому дентин остается почти незащищенным против действия кислот микроорганизмов [16,25]. Вследствие этого развивается бутылочный кариес, по всей пришеечной поверхности [9].…”

Aim. Features of microscopic structure of enamel and dentin of intact temporary teeth, which are the cause of their reduced caries resistance. Materials and methods. Current information in the electronic databases Google Scholar and PubMed was examined through a systematic literature review. Articles with content related to the prevalence of dental caries in temporary teeth and the relationship between caries and tooth hard tissue structure were selected and included. Results. A total of 327 publications were reviewed. After analyzing the literature according to the inclusion criteria, the final number was 52. Conclusions. Based on the analyzed data, the structure of the hard tissues of temporary teeth is a predisposing factor for the occurrence and development of dental caries. Decreased thickness of enamel and dentin, increased concentration of organic matrix in them due to incomplete mineralization, microporosity of enamel, abnormal development of dentin layers, increased number of hypomineralized and irregular areas, underdevelopment of pulp, impaired function of odontoblasts, increased adhesion of microorganisms to the enamel surface – all these features contribute to the rapid and progressive development of caries in temporary teeth.
