“…Today, the existent theory of the exogenous nature of caries has not brought its correctness [6,7,8,9,10,13,18,21,23,25,28]. Thus, it is created a lot of contradictions, the main of them are the next facts that we find in the modern scientific literature [2,5,14,21,33].…”

To date, there is a theory that increased resistance to caries is observed in the teeth, which for any reason underwent destructive changes in the pulp. That is why there is a need to study the impact of pulp vitality on the development of the carious process. The aim of the research was to study the microscopic structure of epoxy sections of intact and carious third molars. We studied 4 intact and 6 carious third molars. For this purpose, specimens were made taking into account the free penetration of the fixative solution into the pulp. To this end, immediately after the tooth was removed, we cut off its roots almost near the crown, preserving the integrity of the latter. The method relied on the impregnation of specimens with epoxy resin, according to the method of epoxy plastination of tooth specimens, developed at the Department of Human Anatomy of Ukrainian Medical Stomatological Academy. The epoxy blocks were cut with a disk into two halves until the hard tissues of the tooth crown were exposed together with the pulp. We found that the hard tissues (dentin and enamel coating) of intact third molars did not have any structural defects. However, their pulp chamber contained mainly an amorphous substance, devoid of any typical pulp tissue structures. That is, the pulp was in a state of complete devolution. Quite the opposite presentation was observed in specimens of carious teeth. We found that their pulp chamber contained quite noticeable tissue structures typical of the dental pulp. It is interesting that in the subodontoblastic layer, in front of the carious alteration of the enamel, there was compaction of the pulp, which may be due to infiltration of perivascular connective tissue by immunocompetent cells. It was found that on the border with carious destruction of enamel, there was a compacted spot of altered dentin, whose matrix was intensely pigmented in brown colour, due to the accumulation of melanin on the dentino-enamel junction. Its excessive formation is associated with the destruction of protein-carbohydrate complexes of organic matter in the deep layers of dentin. We found that the pulp compaction and the focus of carious alteration of the enamel are projectively connected by a radial cord of altered dentin, known in the literature as “dead tracts”. Hence, there is reason to believe that the identified changes indicate a latent form of caries, with a pulpogenic mechanism of development. Thus, it can be argued that the teeth, which for any reason underwent degenerative changes in the pulp, are not prone to carious lesions, whereas in carious teeth, the pulp is active and involved in the pathogenesis of the carious process.

Objectives. Remineralizing therapy is widely used in the treatment of acute initial caries. However, when the protein matrix of the enamel is destroyed in the area of the initial caries, remineralizing therapy turns out to be ineffective, which requires the choice of a different method of treatment. One of these methods is the Icon (Infiltration Concept) enamel infiltration method, which allows to preserve the natural healthy tooth tissues as much as possible and restore the enamel affected by caries. Purpose — to analyze the comparative study of the clinical efficacy of the Icon infiltration method and the deep fluoridation method in the treatment of acute initial caries. Methodology. The article presents the results of studying the clinical efficacy of the Icon infiltration method and the deep fluoridation method in the treatment of acute initial caries of 89 teeth in 50 students of the Medical Academy. S.I. Georgievsky at the age of 18–24. Paraclinical indices were studied: hygiene index (OHI-S), the intensity of dental caries damage (CPU of teeth, CPU of cavities), means of individual hygiene for the oral cavity were selected, general remineralizing treatment was prescribed. To assess the dynamics of treatment, patients were divided into three groups of groups, taking into account the therapy. Results. Clinical application of the Icon infiltration method in the treatment of initial caries made it possible to achieve stabilization of the pathological process and restoration of enamel in 100% of cases — there was a complete disappearance of the focus of demineralization in all teeth, elimination of clinical manifestations of acute initial caries, reduction of the degree of demineralization revealed by vital staining by 83.6%. Conclusions. Our positive results allow us to recommend a wider clinical application of the Icon infiltration method in order to restore enamel in the treatment of initial caries.
