The aim of the study was to compare the obtained data of hard dental tissues destruction indices with the corresponding indications for the choice of the method of treatment by means of mathematical analysis. Materials & methods. 120 patients aged 20 to 55 were examined and 358 teeth hard tissue defects were identified in them. The data of indices was obtained and compared with the indications for orthopedic treatment according two indices in the same clinical situation. Results. The study showed that the indices had different meanings and different indications for treatment in the same situations. Such discrepancies in indications for treatment indicate the subjective data of one of the indices, which does not take into account the depth of destruction and the volume of the remaining natural tissue of the teeth. Comparison of these indices showed different figures in the same clinical situation, identifying corresponding incorrect indications for the choice of the design of the first investigated index, as well as more accurate data of the proposed index. Conclusion. The index assessment of hard dental tissues destruction serves as the main guideline for the dentist when choosing a method for tooth restoration, and can be calculated using photographs, scans and computer software.

After the periodontium of the rat was wounded, the formation of acellular extrinsic fiber cementum (AEFC) did not appear to be restricted to the hard dental tissues (pre-existing cementum, dentin, and enamel). Layers resembling AEFC were also deposited along the inner wall of the alveolar bone. At the time of observation (six weeks after being wounded), cells other than fibroblast-like cells could not be distinguished close to the newly formed AEFC-like layers. We suggest that the deposition of this material was related to the activity of periodontal ligament fibroblasts.

In the problem of solving diagnosis and treatment of hard tissue defects, a significant role is played by the choice of tactics for dental treatment of tooth decay. This work was aimed at studying the problem of diagnosis and systematization of hard tissues defects, that will contribute to the objectification of diagnostic and therapeutic approaches in dental treatment of patients with this disease. The objective of the research was to develop an anatomical and functional systematization for differentiated evaluation of tooth defects, as a basis for the application of differentiated diagnostic and therapeutic approaches to dental treatment of hard tissue defects. Materials and methods. For differential assessment of the extent of tooth defects and precise estimation of the strength of the composition “tooth-restoration”, we conducted   mechanical and mathematical modeling of contact interaction of restoration with dental tissues. We conducted anthropometric studies of all types of cavities of different groups of teeth as well.  Results. As a result of the study, there was proposed the systematization of hard tissues defects – location of defects, occlusive load, extent of defects/ depth of decay. The algorithm for choosing the method of treating hard tissues defects that is based on the systematization of location of defects, occlusive load, extent of defects/ depth of decay and may serve as a selection criterion for the treatment of such pathologies was offered. Conclusions. The proposed systematization filled the obvious gap in academic ideas of hard tissue defects, suggested the prospect of reaching a consensus on differentiated diagnostic and therapeutic approaches in treatment of patients with this disease building the methodological “bridge of continuity” between therapeutic and orthopedic dentistry in the field of hard tissue defect treatment.

The results of a study of occlusal contacts with increased abrasion of the hard dental tissues are presented in the paper. A new technique for determining supercontacts with an elevated abrasion of the teeth with the symptoms of bruxism is described. A study of high contact points will, enable in the future, to conduct therapeutic and preventive measures in order to normalize occlusal relations, when treating and preventing enhanced abrasion.

With the development of the modern concept of tissue engineering approach and the discovery of the potential of stem cells in dentistry, the regeneration of hard dental tissues has become a reality and a priority of modern dentistry. The present review reports the recent advances on stem-cell based regeneration strategies for hard dental tissues and analyze the feasibility of stem cells and of growth factors in scaffolds-based or scaffold-free approaches in inducing the regeneration of either the whole tooth or only of its component structures.

Objectives: To study the influence of environmental pollution on the mineralization of dental hard tissues by using biosubstrates: teeth and hair. :Study design: At the first stage epidemiological survey was conducted in polluted and less polluted areas of Tbilisi (Georgia). We studied 525 children aged 3 and 4 years. Caries prevalence and intensity was defined by the methodology of World Health Organization. At the second stage the chemical elements content was studied in hair and teeth hard tissues of 24 children by X - ray fluorescent spectroscopy method. Results: The prevalence of dental caries in the polluted region was 46%, caries intensity − 1.92 (± 2.842). In the less polluted region prevalence was 37%, caries intensity − 1.47 (± 2.571). These data are statistically reliable (p < 0.05). The study of hair and tooth tissues showed that the toxic elements (Pb, Hg, Sn, Ti) content in these tissues was higher in environmentally unfavorable than in favorable conditions. Conclusion: Hair and dental tissues can be used as indicators of environmental pollution. Our survey showed that toxic elements content in dental hard tissues was higher and the level of essential elements was less in polluted than in less polluted areas of Tbilisi.

Background. Periodontal tissues inflammatory diseases are widespread among young people. Objective. This study was aimed at elaborating the method to assess risks of periodontal inflammatory diseases and determining its efficacy depending on the state of dental tissues, gum tissues and sex.          Methods. The study included 182 students (93 men, 89 women) aged 19-29: 22 individuals had no lesions of hard dental tissues and no signs of periodontal disease; 51 individuals were found to have DMF index <6; 52 individuals – DMF index ≥6; 57 individuals were diagnosed with chronic catarrhal gingivitis. Primary groups were formed in autumn; re-examination was carried in spring. The research participants were assessed for detection of risks of periodontal inflammatory disease by the method developes by the authors (Patent UA 54041). Results. The study revealed that the risk of development of preiodontitis increases in individuals with high caries and gingivitis intensity. In spring, more individuals suffer from microbial imbalance in in the composition of gingival sulcus fluid and decrease in the mean stability coefficient value that indicates an increased risk of inflammatory periodontal disease development. Women were less likely to experience seasonal dysbiotic changes in the gingival sulcus fluid composition compared with men. Conclusions. The method suggested for assessment of the risk of periodontal inflammatory diseases is of high informativeness. It allows clinicians detecting early pre-nosological signs of oral microbiocenosis imbalance that enhances the effectiveness of early diagnosis of inflammatory periodontal diseases.
