(1) Background. Nanotechnology offers significant alternative ways to solve scientific, medical, and human health issues. Dental biomaterials were improved by nanotechnology. It manufactures better materials or improves the existing ones and forms the basis of novel methods for disease diagnosis and prevention. Modern nanotechnology makes oral health care services more acceptable for patients. Nanotechnology is now important area of research, covering a broad range of applications in dentistry. (2) Methods. Relevant literature from Scopus published in English was selected using the keywords “nanoparticle” and “dentistry”. To the selected articles we applied the inclusion and exclusion criteria to choose the relevant ones. (3) Results. Based on the relevant articles, a literature review was prepared. This review provides an insight into the applications of nanotechnology in various branches of dentistry. We applied several regression models to fit number of papers versus time and chose the best one. We used it to construct the forecast and its 95%-confidence interval for the number of publications in 2022–2026. (4) Conclusions. It shows that a significant rise in papers is expected. This review familiarizes dentists with properties and benefits of nanomaterials and nanotechnology. Additionally, it can help scientists to consider the direction of their research and to plan prospective research projects.

Background: Clinical success depends on the contact strength and wear resistance of medical devices made of polymer materials. The scientific goal resulted from the problem of using different methods of surface evaluation of materials used in the production of orthodontic appliances. The purpose of the work was an experimental comparative assessment of indentation hardness and scratch hardness and the sliding wear of four selected polymeric materials used in the manufacture of orthodontic appliances. Methods: Four commercial materials were compared. Shore hardness tests and a scratch test with a Rockwell indenter were performed. A sliding wear test was performed using the ball-on-disc method. Statistical PCA and correlation analyses were performed. Results: The results of scratch hardness measurements using a contact profilometer correlated with the Shore hardness to a greater extent than measurements made using an optical microscope. PCA showed that Shore hardness explains 45% of the total variance in all the results across the materials. Conclusions: The scratch hardness method allows for a more explicit ranking of orthodontic polymeric materials when measurements are made with a profilometer. The ranking of sliding wear resistance should be made separately.

Aim: This study provides a comparative analysis of oral dysbiosis of patients with periodontal diseases: chronic catarrhal gingivitis and generalized periodontitis, associated with various systemic pathologies, using a combination of the enzymatic method and interval scale. Studying the differences in the oral microbiota of patients with periodontal diseases and systemic pathologies can help comprehend the underlying mechanisms and create successful treatments. Methods: An enzymatic method was used to diagnose and monitor the degree of oral dysbiosis of patients with different systemic pathologies and periodontal diseases. We applied particular inclusion and exclusion criteria to include patients in a study. The level of microbial presence in the oral cavity can be measured by analyzing urease enzyme activity. Results: The research established that oral dysbiosis is observed in all groups of patients with periodontal diseases and systemic pathology: chronic colitis, chronic pancreatitis, and primary hypothyroidism. The article discusses an express method of diagnosing the microbiota of the oral cavity in combination with an interval scale. This combination makes it possible to classify patients according to the level of oral dysbiosis and prescribe further recommendations for treatment. Conclusions: The association of periodontitis and linked comorbidities is a complex interplay involving common risk factors, pathophysiology, and bidirectional causal relationships. The imbalance of microorganisms in the oral cavities of patients with systemic and periodontal diseases highlights the need for a personalized medical treatment approach. Correcting dysbiosis of the oral cavity should complement antimicrobial treatment for periodontal diseases and the normalization of metabolic processes in the periodontium. It has been confirmed that there is a correlation between patients’ microbial colonization of the oral cavity and the values obtained by the enzymatic method, suggesting that this approach can serve as a rapid assessment of the oral cavity’s microbiocenosis.

Aim: The aim is to analyze the microbiome of gingival sulcus and periodontal pockets of patients with periodontal disease associated with systemic diseases. Methods: A microbiological study

Large areas become unsuitable for full-fledged life after mining activity. To improve the state of environmental safety of post-industrial landscapes and the rational use of disturbed territories, a Decision Support System (DSS) should be created. This system should also contain proposals for restoring the soil cover and plant communities that are proposed in this article. The purpose of this study is to determine the influence of arbuscular mycorrhizal fungi on the process of vegetation formation in the post-industrial landscape of a sulfur quarry. During reclamation works in human-made ecotopes, vegetation has already formed there in a certain way due to natural succession processes. We assessed the level of vegetation self-restoration and, on the basis of the obtained data, the need and direction of phytoreclamation in relation to specific ecotopes. The set of restoration of soil cover and plant communities makes it possible to solve the problem of reusing post-industrial landscapes. The positive effect of the treatment of seedlings with a spore remedy of arbuscular, mycorrhizal fungi on the studied breeds’ height increase was observed. In the process of the revitalization of disturbed landscapes through the mycorrhization of planting material, there is a tendency to restore and increase phytodiversity at the floristic and coenotic levels.

Numerous studies indicate that periodontal diseases affect a large portion of the adult population, and gum disease is a primary cause of losing teeth in the future. Periodontal diseases are a global health concern. Periodontal diseases are the most common and serious oral illnesses, affecting not only the gums but also the tissue and bone that support the teeth. It begins as gingivitis, a slight swelling of the gums resulting from the buildup of bacterial plaque. If not treated appropriately, it may advance to periodontitis, where the inflammation and infection spread deeper, causing damage to the tissue and bone. The scientific data that deals with stress is vast; it covers different theories of the influence of stress, the consequences of stress on the body and the brain, and the other contributors of stress. The scientific data contains heterogeneous findings about stress's causes, nature, and subsequent effects. Aim: Since stress is a prevalent problem in modern life, the present work aims to estimate the association between stress and periodontal diseases, investigating the central relations highlighted in the scientific data. Methods: The search comprised electronic databases: MEDLINE (PubMed), and Google Scholar, open access journals published by Elsevier. The keywords for the search were "stress," "periodontal diseases," "cortisol," and "saliva" in different combinations. The search considered works published from 2014 until December 2024. The procedure is shown in the PRISMA flowchart. Conclusion: This review highlights the links between physiological stress, the stress hormone cortisol, and periodontal diseases, emphasizing the importance of considering stress as a risk factor in oral health. Understanding these relationships can help clarify discrepancies in treatment effectiveness and inform future healthcare practices.
