The active introduction of innovative technologies, namely 3D printing in dentistry, is of great interest from dentists of various specialties. The use of virtual modeling and printing is actively implemented not only in the work of dental technicians, but also dental surgeons, orthopedists, orthodontists, and doctors of other specialties. Modern technologies allow you to print a surgical template for more accurate and predictable implant placement, plan dental interventions and see the result even before the start of treatment, transfer a prototype of future structures using temporary materials. The article is devoted to the possibility of using a 3D printer for the manufacture of long-wearing crowns. The application of new technologies in dentistry is considered using the example of 3D printing. Possibilities of this technology and the specifics of working with it. Objective: to assess the possibilities of clinical application of long-term wearing crowns made by 3D printing. Methodology. Based on the literature review, and the use of scientific search bibliographic databases: PubMed, eLibrary, Medline, Google Academy, the availability and prevalence of 3D printing technology in dentistry was determined, and in particular its application for printing long-term crowns. Clinical fabrication of long-term crowns was carried out. Conclusions. The emergence of innovative technologies in dentistry, in particular 3D printing, and new materials, are currently attracting active interest from the dental community. 3D modeling and printing are becoming more and more confident in our daily life every day. A thorough study of this method is undoubtedly promising, but it requires deep immersion in the problem, clinical and laboratory observations of structures made of materials for long-term wear.

Introduction. Despite the notable and rapid progress in the development of medical 3D printing in recent years, not much is known about the use of this technology in obstetrics and gynecology.The purpose of our review of scientific literature was to determine the current level of 3D printing development, discuss the closest and long term prospects for using this technology in obstetrics and gynecology, and analyze its potential advantages and disadvantages.Materials and methods. We searched for scientific literature. 378 papers passed a three-step screening, as a result of which 42 sources were selected for the final scientific review.Results and discussion. The main areas in which dimensional printing can be used in this area of medicine is the creation of simulation models and training for students, the creation of anatomical models for preoperative preparation, the surgical instruments, the creation of new dosage drug forms (including transvaginal ones), and bioprinting of organs and tissues.Conclusion. The presented literary review allows us to conclude that 3D printing the obstetrics and gynecology is a current rapidly developing direction. The organization of 3D modeling and printing laboratories can significantly increase the efficiency of teaching students and residents. In addition, obstetricians-gynecologists and surgeons should be informed about the possibility of 3D printing surgical instruments according to an individual design. It can inspire them to implement their own ideas and develop domestic innovative developments. Three-dimensional printing of dosage forms and bioprostheses requires more complex technological solutions, and is not yet used in clinical practice. However, given the enormous prospects for these areas, various grants should be envisaged for their development in Russia

Subject. With the advent of advanced imaging technology and CAD/CAM technologies, the possibility of guided surgery has become of wide interest among implantology. The article is devoted to the use of surgical template implantation in the rehabilitation of a dental patient. It provides information about some advantages and disadvantages of the digital protocol in comparison with traditional dental implantation. The main stages of navigation surgery in a clinical case are described. Goal. To evaluate the actual clinical advantages and disadvantages of dental implant placement using a surgical template compared to the traditional treatment protocol. Methodology. The literature search was conducted in scientific search bibliographic databases such as PubMed, eLIBRARY, Medline, and Google Academy. More than 384 studies up to 2014 were found under the thematic headings "Dental implantation" and "Surgical template". During the study of these works, the sample included 56 articles and literature reviews. Conclusions. Recently, implant placement using a surgical template has become a popular treatment method among dental surgeons. The study of modern literature allowed us to formulate the main advantages and disadvantages of this method. Advantages of the method: precise positioning of implants; flap-free surgery reduces the operation time and is characterized by a favorable postoperative course; integration of restoration determinants in surgical planning, which leads to a more aesthetic, functional and predictable result of prosthetics; the possibility of pre-manufacturing a prosthesis based on the planned position of the implant; simplification of the surgical procedure for the dentist. However, this method is not without its drawbacks: the surgeon's inability to visualize anatomical structures; the risk of axis and depth deviation during implant placement; requires additional digital planning.

A Review of: Clarke, M. A., Belden, J. L., Koopman, R. J., Steege, L. M., Moore, J. L., Canfield, S. M., & Kim, M. S. (2013). Information needs and information-seeking behaviour analysis of primary care physicians and nurses: A literature review. Health Information & Libraries Journal, 30(3), 178-190. http://dx.doi.org/10.1111/hir.12036 Abstract Objective – To improve information support services to health practitioners making clinical decisions by reviewing the literature on the information needs and information seeking behaviours of primary care physicians and nurses. Within this larger objective, specific questions were 1) information sources used; 2) differences between the two groups; and 3) barriers to searching for both groups. Design – Literature review. Setting – SCOPUS, CINAHL, OVID Medline, and PubMed databases. Subjects – Results from structured searches in four bibliographic databases on the information needs of primary care physicians and nurses. Methods – Medical Subject Heading (MeSH) and keyword search strategies tailored to each of four databases were employed to retrieve items pertinent to research objectives. Concepts represented in either controlled or natural language vocabularies included “information seeking behaviour, primary health care, primary care physicians and nurses” (p. 180). An initial yield of 1169 items was filtered by language (English only), pertinence to study objectives, publication dates (2000-2012), and study participant age (>18). After filtering, 47 articles were examined and summarized, and recommendations for further research were made. Main Results – Few topical differences in information needed were identified between primary care physicians and nurses. Across studies retrieved, members of both groups sought information on drugs, diagnoses, and therapy. The Internet (including bibliographic databases and web-based searching) was the source of information most frequently mentioned, followed by textbooks, journals, colleagues, drug compendiums, professional websites, and medical libraries. There is insufficient evidence to support conclusions about the differences between groups. In most research, information needs and behaviours for both groups have been discussed simultaneously, with no real distinction made, suggesting that there may not be significant differences even though a few studies have found that nurses’ emphasis is on policy and procedures. Barriers to access include time, searching skills, and geographic location; for the last, improvements have been made but rural practitioners continue to be adversely affected by limited access to people and resources. Conclusion – Both primary care physicians and nurses seek information on diagnosis and treatment. The Internet is of increasing utility for both groups, but all resources have advantages and disadvantages in identifying evidence based information for use in practice. Further research is required to support access and use of evidence based resources, and to explore how focused, evidence based information can be integrated into electronic health record systems.

Objetivo: Bio-Oss is a xenogene bone graft in which all organic components are removed while retaining their natural mineral architecture. Therefore, the aim of this study was to evaluate, through a literature review, the benefits of using Bio-Oss for tissue regenerative treatment prior to implant placement. Material and Methods: a search was performed in Pubmed (Medline) in order to identify articles published in English between January 1, 2000 and June 31, 2018, where the Bio-Oss graft was used prior to implantation of implants in humans. A total of 40 studies were selected for detailed analysis. From this analysis, 18 articles were identified for inclusion in this review. Results: the articles analyzed in the review showed several beneficial effects of this xenograft, such as: positive osteoconductive properties, recovery of bone heights at sites with severe atrophies, slow xenograft reabsorption suggesting long term stability, survival rates and success of implants placed in grafted sites ranging from 91 to 100% in several studies. Conclusion: the use of bio-oss as a bone substitute is a viable alternative in the placement before dental implants, being used in clinical practice and with proved efficacy in several studies, due to its similarity with the bone and its high level of osteoconductivity.KeywordsBio-Oss; Bone Graft; Implants.

Subject. Since the mid-20th century, there has been an increase of interest in implantation for the treatment of partial and complete loss of teeth. P. I. Branemark was one of the first pioneers who developed an implant that forms osseointegration. Anatomical restrictions and restorative requirements prompt the implantologist to achieve the accuracy of planning and surgical positioning of dental implants. The ideal placement of the implant facilitates the creation of favorable forces on implants and prosthetic structures, and also provides an aesthetic result. Therefore, it is advisable to establish a logical continuity between the planned restoration and the surgical stages, it is important to use the transmitting device, which undoubtedly increases the effectiveness of the implantation. In 1987, M. J. Edge et al. recommended the use of surgical guides before the implantation operation. Currently, surgical templates have become increasingly used. The article presents data on the features of planning of implant placement and the technology of applying a surgical template for positioning the dental implant unit. Goal. To show the value of using surgical templates for the rational installation of dental implants and preventing possible errors and complications. Methodology. A search for literature using search engines such as Google, Yahoo and scientific bibliographic databases such as PubMed, Medline and textbooks was conducted until September 2017 using medical thematic headings like «Dental Implants», «Surgical Templates». More than 300 sources of literature were identified, after studying which they reduced to 28 sources of articles and literary reviews. Conclusions. The study of available to us literature, revealed the advantages and disadvantages of using surgical templates. The main advantages: precise placement of implants, preservation of anatomical structures; three-dimensional technology allows to accurately estimate anatomical points, such as the size of the maxillary sinus in the upper jaw and the location of the alveolar nerve in the lower jaw, high observable accuracy of 0.1 mm, reduction of the time of surgical intervention. Disadvantages: lack of visibility and tactile control during the surgical procedure, insufficient opening of the mouth jeopardizes the result of complex treatment, there is a risk of damage to vital anatomical structures.

AbstractAssume that a researcher uncovers a major problem with how social media are currently used. What sort of challenges arise when they must subsequently decide whether or not to use social media to create awareness about this problem? This situation routinely occurs as ethicists navigate choices regarding how to effect change and potentially remedy the problems they uncover. In this article, challenges related to new technologies and what is often referred to as ‘Big Tech’ are emphasized. We present what we refer to as the AI ethicist’s dilemma, which emerges when an AI ethicist has to consider how their own success in communicating an identified problem is associated with a high risk of decreasing the chances of successfully remedying the problem. We examine how the ethicist can resolve the dilemma and arrive at ethically sound paths of action through combining three ethical theories: virtue ethics, deontological ethics and consequentialist ethics. The article concludes that attempting to change the world of Big Tech only using the technologies and tools they provide will at times prove to be counter-productive, and that political and other more disruptive avenues of action should also be seriously considered by ethicists who want to effect long-term change. Both strategies have advantages and disadvantages, and a combination might be desirable to achieve these advantages and mitigate some of the disadvantages discussed.

The objective of the present study was to carry out a literature review on “self-care” or, in English, “Over-the-counter” (OTC) bleaching products, consulting articles in the Pubmed and Scielo databases, between the years 2000 and 2019, in order to evaluate its characteristics, advantages and disadvantages of use. We can conclude that the majority of whitening dentifrices and rinses on the market do not have a clinically significant whitening action; in relation to dental strips or strips, they have satisfactory whitening efficacy. However, it is important to emphasize the need for further long-term studies to affirm whether these products are really safe and efficient, since their advantages and disadvantages become doubtful and questionable. Therefore, guidance and monitoring by the dental surgeon in the handling and prescription of such products is extremely important, after all, if used in an indiscriminate and erroneous way, they can cause potentially harmful data to the patient.
