The purpose of the study was to determine a number of clinical cases of dental implantation with insuficient height of the alveolar ridge based on data of consumption of the dental implants of various designs in dental healthcare institutions during 10 years. Materials and methods. The research was performed on the provided information on the sales of dental implants produced by the DENTIUM corporation, “SuperLine” and “SuperLine NEW” (Korea) from the official supplier in Ukraine (“Stamil” group of companies) for the period 2013–2022. Results and discussion. Quality and sufficient volume of bone tissue around the dental implant is an important condition to achieve an optimal level of osseointegration. In cases of a shortage of available bone an additional option in the choice of treatment tactics is the installation of short dental implants. Compared with dental implants of standard and extended length the short implants showed a higher frequency of rejection and early disintegration. The length of the dental implant body is a critical factor in the long-term successful functioning of implants which is ambiguously evaluated and described in the professional literature. The analysis in the subgroups of the use of short implants showed that in the vast majority of cases, dental implants with a length of 8.00 mm were used – in the volume of ten-year implementation, their specific weight was 24.92%. Accordingly, it can be assumed that the volume of application of such structures is identical to the specific gravity of cases of minimal deficit in the height of the bone tissue of the alveolar crest of the jaws – 2.00 mm. The use of descriptive statistics methods made it possible to calculate the average percentage of such clinical cases – 23.92 ± 5.71 mm (M=25.37 mm). In calculations per decade the specific weight of cases of the alveolar ridge height deficiency of the jaws (lack of available bone tissue) was 30.03%. The average value was 28.80 ± 6.74% (M=30.95%), the minimum – 19.11% and the maximum – 38.08%. There were only 1.42% cases of “compensation” of the short implant length by increasing its diameter (upto 6.00 and 7.00 mm) in the overall structure of the performed operations. The usage of average annual number of short dental implants of increased diameter (from 6.00 mm) was 0.67 ± 0.28% (M=0.56%). The analysis of dynamics of the usage of short dental implants (7.00 mm and 8.00 mm) over ten years period revealed unevenness. For implants with a length of 8.00 mm frequency varied between 15.00–30.00%. The usage of shorter structures (length 7.00 mm) did not have such critical changes – minor deviations near 5.00%. Conclusion. The obtained results allowed to determine indirectly the prevalence of the alveolar ridge height deficiency in patients of “implantation cohort” in Ukraine during the last 10 years
Relevance. Bone-graft materials are widely used in health care and dentistry in particular. The use of osteoplasty techniques in the oral cavity has an increased risk of contamination of the operating field with opportunistic and pathogenic microflora. A number of improvements in such materials have the potential to be used in the treatment of dental diseases. Objective: to analyze current publications devoted to the improvement of bone gratf materials that are used in health care and can be used in dentistry. Methods. An analysis of data obtained during an information search in the online databases "PubMed", "SciELO", "Medcape" and "Science of Ukraine: access to knowledge" was carried out using the keywords "osteoplasty", "bone substitute materials", " bone defects". Results: Despite the predominance in clinical practice of the use of osteoplastic materials of animal origin, the development and improvement of artificial materials looks promising. Such directions can be the improvement of composite materials based on hydrophilic gels which are able to be resorbed in the human body. Modification of ceramic materials and biological glass, improvement of their osteoconductive properties. Inclusion of antibiotics and antiseptics to osteoplastic materials. Inclusion of natural and recombinant biological growth factors in the composition of bone substitute materials. Transformation of osteoplastic material into a system of controlled long-term emission of antibiotics, antiseptics and biological growth factors. Conclusions: Modern osteoplastic materials used in dentistry are mainly high-tech medical products that continue to be improved. The creation of artificial and composite materials with additional antiseptic, antibacterial, osteoinductive and biological properties opens the way to improving the methods of dental treatment and osteoplasty for the needs of dentistry.
The purpose of the study was to compare an adhesion strength of some modern enamel sealants to the enamel of a developing tooth which occurs without adhesive preparation of tooth surface. Materials and methods. In laboratory the shear adhesion strength to human teeth enamel without adhesive system application was compared for “Fissurit FX” (VOCO), “Clinpro™ Sealant” (3M™ ESPE™) and “Jen-Fissufil” (Jendental-Ukraine LLC). 30 samples were tested on tensometric system. Tests were performed according to requirements of ISO 4049:2019 “Dentistry – Polymer-based restorative materials” and ISO 6874:2005 “Dentistry – Polymer-based pit and fissure sealants”. Results and discussion. Performed experimental studies of sealant adhesion (without the use of adhesive systems, only with acid etching) showed that it was the largest in the domestic “Jen-Fissufil” – 9.80 ± 1.17 MPa (M=10.42 MPa, min – 7.41 MPa, max – 11.07 MPa); less in “Fissurit FX” – 9.78 ± 1.33 MPa (M=9.43 MPa, min – 8.23 MPa, max – 12.62 MPa) and “Clinpro™ Sealant” – 9.55 ± 1.88 MPa (М=8.69 MPa, min – 6.35 MPa, and max – 14.73 MPa). The performed statistical tests did not reveal any significant differences between the adhesion strength in all three subgroups. Due to the changes in the concept of dental caries development and approaches to its control that have taken place in dentistry over the past 30 years, the role of enamel sealants in achieving caries control in individual and communal prevention of dental diseases has significantly increased. The tendency to expand the indications for the use of photocomposite enamel sealants in clinical practice is also worth noting. In addition to their direct purpose, the materials can be used for “repair” and restoration of individual photocomposite fillings with minor wear and used as a lining material for the restoration of teeth with carious cavities with a high C-factor. Conclusion. In modern dentistry the use of enamel photocomposite sealants is one of the most effective and reliable methods of preventing caries of the occlusal surfaces of teeth. The study of shear adhesion to acid-etched enamel for photocomposite materials “Fissurit FX”, “Clinpro™ Sealant” and “Jen-Fissufil” did not reveal any significant differences. The technology of composite tooth enamel sealants is currently successful in clinical practice and continues to improve and develop. The development of new and quality improvement of such materials is an urgent issue for science and technology
The purpose of the work was to study the world literature on the socio-economic determinants of dental health among children. Materials and methods. An online information search was performed in the databases “PubMed”, “SciELO”, “Medcape” and “Science of Ukraine: access to knowledge” using the keywords “children caries”, “dental (oral) health”, “children and adolescents”, “social and economic determinants of health” with appropriate translations in foreign languages. Results and discussion. At the global level, dental diseases lead to serious medical and economic consequences which manifest themselves in the form of a significant decrease in the quality of life. The foundations of the dental health level are laid in childhood and are strengthened in adolescence, so these age groups of the population are the main “target audience” for disease prevention measures, valeological research, sanitary and educational work and the formation of appropriate habits. Socio-economic determinants of dental health in children, adolescents and adults on a global scale have been studied unevenly. Mostly, the results of research performed in the developed countries of the world are available. Such a situation creates a need for rethinking approaches and methods for assessing the problem of health care systems in separate countries and changing the methods for developing measures to influence the dental health of children and adolescents with high individualization and adaptation of socially oriented program products in health care. Giving a priority in the development of preventive programs in the field of health care to only individual and collective training measures and communal prevention does not allow to neutralize the negative impact of socio-economic conditions, and even more – it deepens inequality in dental health in the population, which is recognized as a problem by the World Health Organization. With regard to Ukraine, the presence of martial law and the continuation of fighting in certain countries have caused a number of demographic and socio-economic processes, which will be measured and evaluated after some time. But, unequivocally, the existing economic crisis, a decrease in the level of income of the population, negative demographic processes, complications of work in the health care system and other factors that can be defined as determinants of children's dental health continue to operate. Therefore, it is expected that we should be prepared for the deterioration of dental health indicators at the national level and the negative consequences of this. Conclusion. The main socio-economic determinants of children's dental health are recognized as: the level of economic development of the country, access to medical and dental care, the level of family wealth, the age and level of education of parents, their employment, the number of children in the family, the migration status of the family and separately – parents, local peculiarities of the culture of oral cavity care and nutrition, availability and level of coverage of educational and sanitary-educational measures, local levels of development of the system of health care institutions, effectiveness of interaction between health care institutions, education and social protection management bodies
