Recent Trends and Future Direction of Dental Research in the Digital Era.

The digital transformation in dental medicine, based on electronic health data information, is recognized as one of the major game-changers of the 21st century to tackle present and upcoming challenges in dental and oral healthcare. This opinion letter focuses on the estimated top five trends and innovations of this new digital era, with potential to decisively influence the direction of dental research: (1) rapid prototyping (RP), (2) augmented and virtual reality (AR/VR), (3) artificial intelligence (AI) and machine learning (ML), (4) personalized (dental) medicine, and (5) tele-healthcare. Digital dentistry requires managing expectations pragmatically and ensuring transparency for all stakeholders: patients, healthcare providers, university and research institutions, the medtech industry, insurance, public media, and state policy. It should not be claimed or implied that digital smart data technologies will replace humans providing dental expertise and the capacity for patient empathy. The dental team that controls digital applications remains the key and will continue to play the central role in treating patients. In this context, the latest trend word is created: augmented intelligence, e.g., the meaningful combination of digital applications paired with human qualities and abilities in order to achieve improved dental and oral healthcare, ensuring quality of life.

Commentary: Challenges and Opportunities for Women in Dental Research.

This commentary integrates and expands on the preceding articles in this issue that document and celebrate a century of women's achievements in the International Association for Dental Research (IADR). The increasing participation and leadership of women in dental and craniofacial research and within the IADR were viewed from the perspective of a changing culture of science. The steps that have been taken by the IADR to develop greater inclusiveness are acknowledged, and some of the challenges that remain are discussed in terms of obstacles that are most often social or cultural in origin. Comparisons are made across countries, and the social determinants that lead to differences in women's participation are described. Recommendations are made for developing strategies to change elements of our institutional cultures that have provided advantages to some groups of researchers more than to others. The unconscious biases and a lack of commitment to diversity, equity, and inclusion that limit the participation of members of some groups limit the progress and achievements of science in general.

Empowering Women Researchers in the New Century: IADR's Strategic Direction.

Gender inequality in science, medicine, and dentistry remains a central concern for the biomedical research workforce today. Although progress in areas of inclusivity and gender diversity was reported, growth has been slow. Women still face multiple challenges in reaching higher ranks and leadership positions while maintaining holistic success in these fields. Within dental research and academia, we might observe trends toward a more balanced pipeline. However, women continue to face barriers in seeking leadership roles and achieving economic equity and scholarship recognition. In an effort to evaluate the status of women in dental research and academia, the authors examined the role of the International Association for Dental Research (IADR), a global research organization, which has improved awareness on gender inequality. The goal of this article is to review five crucial issues of gender inequality in oral health research and academics-workforce pipeline, economic inequality, workplace harassment, gender bias in scholarly productivity, and work-life balance-and to discuss proactive steps that the IADR has taken to promote gender equality. Providing networking and training opportunities through effective mentoring and coaching for women researchers, the IADR has developed a robust pipeline of women leaders while promoting gender equality for women in dental academia through a culture shift. As knowledge gaps remained on the levels of conscious and unconscious bias and sexist culture affecting women advancement in academics, as well as the intersectionality of gender with race, gender identity, ability status, sexual orientation, and cultural backgrounds, the IADR has recognized that further research is warranted.

[Changes in the "classical" factors influencing dental implant-osseointegration in recent decades]. / A fogászati implantátumok csontbeépülését befolyásoló "klasszikus" tényezok változásai az elmúlt évtizedekben.

Nowadays, it is almost naturally taken among dentists that seemed unimaginable a few decades ago, namely that an inorganic material (titanium) inserted in an organic environment (bone) can be integrated and become a permanent pillar of prosthetics. Bone integration - meaning a structural and functional connection between the implant and the bone - itself was discovered and described in the late 1960s. This provides the basis of dental implantology. In those days, the conditions affecting the positive or negative course of bone integration have been formulated. This process is investigated at the level of basic research and rarely mentioned in the daily clinical practice. The material, form, and surface of the implant all contribute to success if we design well and apply the correct surgical technique. Our goal is to present the changes that have taken place over the past decades, which have resulted in an increasingly perfect integration and clinical success of implants.

Health Data in Dentistry: An Attempt to Master the Digital Challenge.

BACKGROUND: Biomedical research has recently moved through three stages in digital healthcare: (1) data collection; (2) data sharing; and (3) data analytics. With the explosion of stored health data (HD), dental medicine is edging into its fourth stage of digitization using artificial intelligence (AI). This narrative literature review outlines the challenge of managing HD and anticipating the potential of AI in oral healthcare and dental research by summarizing the current literature. SUMMARY: The basis of successful management of HD is the establishment of a generally accepted data standard that will guide its implementation within electronic health records (EHR) and health information technology ecosystems (HIT Eco). Thereby continuously adapted (self-) learning health systems (LHS) can be created. The HIT Eco of the future will combine (i) the front-end utilization of HD in clinical decision-making by providers using supportive diagnostic tools for patient-centered treatment planning, and (ii) back-end algorithms analyzing the standardized collected data to inform population-based policy decisions about resource allocations and research directions. Cryptographic methods in blockchain enable a safe, more efficient, and effective dental care within a global perspective. Key Message: The interoperability of HD with accessible digital health technologies is the key to deliver value-based dental care and exploit the tremendous potential of AI.

Proceedings of the American Association of Oral and Maxillofacial Surgeon's 2017 Clinical and Scientific Innovations in Oral and Maxillofacial Surgery (CSIOMS).

The sixth biennial Clinical and Scientific Innovations in Oral and Maxillofacial Surgery, formerly the Research Summit, of the American Association of Oral and Maxillofacial Surgeons and its Committee on Research Planning and Technology Assessment was held in Rosemont, Illinois from April 28 to 30, 2017. The goal of the symposium is to provide a forum for the latest clinical and scientific advances to be brought to the specialty. It also nurtures collaboration and the development of relationships between oral and maxillofacial surgeons and researchers to bridge the gap between clinical and basic science. The goal is to improve the care of oral and maxillofacial surgical patients through the advancement of translational and clinical research.

Clinical studies in restorative dentistry: New directions and new demands.

Clinical research of restorative materials is confounded by problems of study designs, length of trials, type of information collected, and costs for trials, despite increasing numbers and considerable development of trials during the past 50 years. This opinion paper aims to discuss advantages and disadvantages of different study designs and outcomes for evaluating survival of dental restorations and to make recommendations for future study designs. Advantages and disadvantages of randomized trials, prospective and retrospective longitudinal studies, practice-based, pragmatic and cohort studies are addressed and discussed. The recommendations of the paper are that clinical trials should have rational control groups, include confounders such as patient risk factors in the data and analysis and should use outcome parameters relevant for profession and patients.

Clinical studies in restorative dentistry: Design, conduct, analysis.

OBJECTIVE: Clinical studies should be one main aspect underlying dentists' decision-making towards dental materials. Study design, conduct, analysis and reporting impact on the usefulness of studies. We discuss problems with current studies and highlight areas where improvement might be possible. METHODS: Based on systematically and non-systematically collected data, we demonstrate where and why current studies in clinical dentistry deliver less-than-optimal results. Lending from general medicine, we suggest ways forward for clinical dental material science. RESULTS: Randomized controlled (efficacy) trials remain a major pillar in dental material science, as they reduce selection bias and, if well-designed and conducted, have high internal validity. Given their costs and limited external validity, alternatives like practice-based or pragmatic controlled trials or observational studies can complement the evidence-base. Prior to conduct, researchers should focus on study comparators and setting (answering questions with relevance to clinical dentistry), and pay attention to statistical power, considering the study aim (superiority or non-inferiority trial), the expected event rate, and attrition. Study outcomes should be chosen on the basis of a core outcome set or, if not available, involving patients and other stakeholders. Studies should be registered a priori, and reporting should adhere to standards. Possible clustering should be accounted for during statistical analysis. SIGNIFICANCE: Many clinical studies in dental material science are underpowered, and of limited validity and usefulness for daily decision-making. Dental researchers should mirror existing efforts in other medical fields in making clinical studies more valid and applicable, thus contributing to better dental care.

Trends in restorative composites research: what is in the future?

Clinical trials have identified secondary caries and bulk fracture as the main causes for composite restoration failure. As a measure to avoid frequent reinterventions for restoration replacement, composites with some sort of defense mechanism against biofilm formation and demineralization, as well as materials with lower susceptibility to crack propagation are necessary. Also, the restorative procedure with composites are very time-consuming and technically demanding, particularly concerning the application of the adhesive system. Therefore, together with bulk-fill composites, self-adhesive restorative composites could reduce operator error and chairside time. This literature review describes the current stage of development of remineralizing, antibacterial and self-healing composites. Also, an overview of the research on fiber-reinforced composites and self-adhesive composites, both introduced for clinical use in recent years, is presented.

Oral Health Research and Scholarship in 2040: Executive Summary.

This executive summary for Section 6 of the "Advancing Dental Education in the 21st Century" project provides an overview of five background articles that address the role of research and scholarship in dental education in the year 2040. Beginning with a historical account of research and discovery science in dentistry's evolution as a profession, the article then reviews the role of early thought leaders and organized dentistry in establishing research as a cornerstone of dental education and dental practice. The dental research workforce faces an uncertain future fueled by a volatile funding environment and inadequate mentoring and training of research faculty. Dental schools must forge stronger academic and scientific ties to their university and academic health centers and will be challenged to develop sustainable research and patient care collaborations with other health professions. The changing health care environment will create new opportunities for oral health care providers to expand their scope of practice and focus on prevention and screening for non-communicable chronic diseases. Dental practitioners in the future are likely to place greater emphasis on managing the overall health of their patients while promoting closer integration with other health professionals. All dental schools must develop a sustainable research mission if they hope to graduate dentists who function effectively in a collaborative health care environment. The changing scientific and health care landscape will dramatically alter dental education and dental practice. Dental schools need to reconsider their research and educational priorities and clinical practice objectives. Until dental schools and the practicing community come to grips with these challenges, a persistent attitude of complacency will likely be at the dental profession's peril.

Evaluation of scientific output in Dentistry in Spanish Universities

Background: The aim of this study was to assess the scientific output of Spanish universities that offer a bachelor’s degree in dentistry through the use of various bibliometric indicators. Material and Methods: A total of 21 universities offered a bachelor’s degree in dentistry in academic year 2016- 2017. The search for papers published by authors associated with these institutions was carried out using the selection of journals listed in the Journal Citation Reports (JCR) and the Web of Knowledge database for the period 1986-2017. On the basis of these data, we determined the output, the h-, g- and hg-indexes, the most productive authors, international collaborations, and the most relevant journals. Results: Public universities obtained better results than private universities. The University of Valencia was ranked first, followed by the Complutense University of Madrid and the University of Granada. The most productive author was José Vicente Bagán, but the author with the highest h-index was Mariano Sanz and Manuel Toledado. The universities with the greatest output and highest citation rates had more international collaborations. The most developed fields in Spanish universities were Oral surgery, Oral medicine and Dental materials. The universities had different models of production. At universities such as Barcelona or Valencia, the production was focused on very few departments and authors. At the other extreme, the University of Granada had various sources of research and authors, which meant that its output and citation rate could increase more. Conclusions: University faculties must provide suitable academic and research training, and therefore must be assessed using objective criteria and bibliometric tools. Although the number of university schools and faculties that teach dentistry has increased, and particularly the number of private universities, there is no correlation between their quality and output and the number of places offered on their courses (AU)

Utilizing three-dimensional data in orthodontic practice and research.

The recent prevalence of three dimensional (3D) images of soft and hard tissues provides a wealth of new data from which the clinician can evaluate these changes. However, evaluating this new data presents new and significant challenges. Current approaches utilizing multi-dimensional data for the precise evaluation of changes related to treatment and growth sets are reviewed. The results of current validation studies exploring approaches to these problems are reviewed, including the registration of longitudinal data using maxillary and mandibular regions of reference. Challenges related to the consistent selection of points on complex three-dimensional structures are circumvented using an automated, shape analysis based approach. Imaging using these new modalities yields a tremendous amount of data. Analysis of large data sets from cross-sectional studies with multiple variables are simplified using a principle components analysis, from which a reduced set of variables is constructed. Examples of this approach are presented. The use of advanced methods to process and interpret data from 3D imaging modalities highlights critical aspects of craniofacial growth and form.
