The influence of microbial persistence of dental plaque on the pathogenesis and course of generalized periodontitis Demkovych, A. Ye.; Poliukhovych, Y. I.; Hasiuk, P. A.; Мykolenko, А. Z.; Vorobets, A. B.; Beliaiev, E. V. Introduction. In the pathogenesis of chronic inflammation of periodontum, dental plaque penetrates to the bottom of the gingival sulcus and enters the connective tissue interstitium under the epithelium, causing inflammation. Aim. The aim of this research is to conduct an analysis of modern scientific publications regarding the influence of microbial persistence of dental plaque on the pathogenesis and course of generalized periodontitis. Materials and methods. The search and selection of publications, systematic reviews and current recommendations was carried out using PubMed and Google Scholar databases. Results. Іnflammation increases the outflow of cerebrospinal fluid and in this way significantly improves the conditions for the reproduction of microorganisms in the area of the newly created peculiar pathological ecological niche – the periodontal pocket. In addition, inflammation stimulates the vegetation of the epithelium in the direction of the apex of the root part of the tooth, which is limited by the compact plates of the periodontal gap. It is the vegetation of the epithelium that causes a defect in the epithelial cover of the bottom of the gingival sulcus and cuts off the periodontal ligaments. The periodontal ligaments are replaced by granulation tissue, significantly increasing the surface area of the outer covering infiltrated with plaque microbiota. P. gingivalis is one of the main pathogens involved in periodontitis. The predominance of Porphyromonas gingivalis in tissues is a bad prognostic sign in typical forms of periodontitis. After Aggregatibacter actinomycetemcomitans, it is the most prevalent causative agent of chronic generalized periodontitis. It is especially often found in fresh lesions of the periodontal complex. Among all representatives of the oral microbiocenosis and pathogens, Porphyromonas gingivalis shows the strongest correlation with chronic periodontitis. Conclusions. Microbiological diagnostics allows obtaining the necessary information for the selection of the drug and the method of systemic therapy using antibiotics, as well as for monitoring and evaluating the effectiveness of the selected method of antibacterial therapy.

The use of 3D printers for the manufacture of complex multi-component dentures in dentistry Domysche, M.; Terekhov, S.; Astapenko, O.; Vefelev, S.; Tatarina, O. Introduction: three-dimensional (3D) printing has transformed dentistry by enhancing precision, efficiency, and reducing material waste in prosthesis manufacturing. The objective of this study is to evaluates (3D) printing effectiveness and operational parameters by assessing technology used, workflow efficiency, patient outcomes and complications in dental procedures, focusing on its clinical applicability and impact on patient care. Method: a systematic literature review was done for articles from 2015 to 2024. A systematic search of multiple databases, including PubMed and Google Scholar, yielded 3785 studies, which were narrowed to 15 studies that focused on 3D printing technology in multi-part dental prostheses. Results: the 3D-printed material was compared with conventional rapid prototyping material, and good strength characteristics of the prostheses were achieved. 3D-printed prostheses’ long-term performance depends on constantly developing techniques and technologies. 3D-printed prosthesis accuracy was relatively high, but patient throughput, complexity, and limited precision needed to be more satisfactory. Literature reviews, randomized controlled trials, single-centre clinical trials, and in vitro and observational studies were also included in this study. Conclusions: although limitations about material properties, production costs, and accuracy still exist, the prospects of 3D printing for clinical application in dental prosthetics are very encouraging. Enhanced digital workflows have positively impacted patient engagement, yet additional research is needed to improve such practices in the clinic for maximal patient satisfaction.

Evaluating the impact of modern laser technologies on dentistry in European union countries Chertov, S.; Тatarina, O.; Karkimbayeva, G.; Rysbayeva, Z.; Dovzhuk, N. Introduction: in dentistry, understanding laser wavelength interactions with oral tissues enhances patient management. Over two decades, lasers have been used in dental practices for diagnostics, caries detection, calculus identification, hard tissue cutting, and root canal disinfection. They reduce patient anxiety and the need for anesthesia in hard tissue applications. Aim: the objective of this research is to provide a review on how European dentistry has been affected by the use of modern laser technology between 2020 and 2024. This was done by classifying the types of lasers, examining their uses in different dental treatments, investigating the problems that may arise as a result, and appraising the benefits for oral health and patient outcomes. Method: a systematic literature review was conducted from 2020 to 2024, focusing on modern laser technologies in dentistry within European countries. Using the PRISMA flow diagram, studies were identified, screened, and included based on keywords related to dentistry and laser technologies. Initial searches identified 17,130 records, narrowed down to 27 relevant studies through various criteria. Inclusion required studies to focus on dental laser applications in specified European countries, published between 2020 and 2024, and be peer-reviewed. Results: the review covered studies from 2020 to 2024, highlighting various dental specialties and laser technologies like Erbium, CO2, Diode, Nd, Excimer, and Fiber lasers. Finding indicated lasers improved precision, reduced discomfort, and enhanced patient outcomes with minimal postoperative pain and faster recovery times. Noted risks included thermal damage and specific complications like bleeding and pain. Conclusions: the review highlights lasers’ transformative potential in EU dental care, offering precision and improved outcomes. Future research should standardize protocols, assess long-term benefits and risks, focus on safety, and integrate patient-centered outcomes to enhance the evidence base supporting laser technologies in routine dental care.

Correlations of teleradiometric “dental” indicators according to the Ricketts method with the sizes of teeth and dental arches in Ukrainian young men and young women with physiological occlusion without and taking into account the type of face Brotskyi, N. O.; Dmitriev, М. О.; Beliaiev, E. V.; Piliponova, V. V.; Kyrychenko, I. M. Annotation. Studying the relationship between the morphological characteristics of the dentofacial system and the parameters of the craniofacial region is important for understanding the mechanisms of formation of a harmonious bite. Analysis of such correlations allows predicting the features of the development of dental arches and developing personalized approaches to orthodontic treatment. Taking into account individual variations in the size of teeth and their correlation with craniofacial parameters contributes to the optimization of diagnostics and planning of orthodontic intervention. The study of these parameters in representatives of the Ukrainian population allows identifying characteristic morphological features and their variability. The aim of the study was to establish qualitative and quantitative features of correlations between “dental” teleradiometric indicators according to the Ricketts method with the sizes of teeth and dental arches in Ukrainian young men and young women with physiological occlusion without and taking into account the type of face. The computed tomographic sizes of teeth, dental arches and “dental” teleradiometric indicators according to the Ricketts method (distances 6u-6l, Overjet, Overbite, 1l-OcP, 3u-3l and angle Max1-Mand1) were determined from the data bank of the Research Center and Department of Pediatric Dentistry of the National Pirogov Memorial Medical University, Vinnytsya from primary computed tomograms of 41 Ukrainian young men (aged 17 to 21 years) and 68 Ukrainian young women (aged 16 to 20 years) with physiological occlusion. The Garson face types of this contingent were also determined. The assessment of correlations between “dental” teleradiometric indicators according to the Ricketts method and computed tomography dimensions of teeth and dental arches in young men and young women without and taking into account the type of face was carried out in the licensed package “Statistica 6.0” using nonparametric Spearman statistics. As a result of the analysis of reliable and medium-strength unreliable correlations between “dental” teleradiometric indicators according to the Ricketts method with the dimensions of teeth and dental arches, the following was established: in young men and young women without taking into account the type of face - respectively 4.76 % and 14.29 % of connections with the dimensions of the teeth of the upper jaw, respectively 11.43 % and 16.67 % of connections with the dimensions of the teeth of the lower jaw and respectively 8.33 % and 6.48 % with the dimensions of the dental arches; in young men and young women with a wide face type – respectively 13.81 % and 14.29 % of connections with the size of the teeth of the upper jaw, respectively 21.90 % and 12.38 % of connections with the size of the teeth of the lower jaw and respectively 16.67 % and 17.59 % of connections with the size of the dental arches; in young women with a very wide face type – 19.05 % of connections with the size of the teeth of the upper jaw, 19.05 % of connections with the size of the teeth of the lower jaw and 17.59 % of connections with the size of the dental arches. In young men and young women, both regardless of facial type and in representatives with a wide facial type, pronounced manifestations of sexual dimorphism of the relationships between “dental” teleradiometric indicators according to the Ricketts method and computed tomography dimensions of teeth and dental arches were established in terms of the strength, number, and direction of reliable and medium-strength unreliable correlations.
