Global Dental Publications in PubMed Databases between 2009 and 2019-A Bibliometric Analysis

Estimating the use of ChatGPT in dental research publications

INTRODUCTION

Generative artificial intelligence (GenAI) Large-language models such as ChatGPT have become increasingly popular in various fields. However, the impact of ChatGPT on dental research writing has yet to be quantified. This study aimed to assess ChatGPT's usage in dental research writing and discuss potential advantages and challenges.

METHODS

Using a bibliometric design, we performed a keyword analysis of specific 'signaling words' indicative of ChatGPT use in the titles/abstracts of 299,695 dental research abstracts indexed PubMed 2018-2024. Statistical comparisons using normalized ratios per 10,000 dental publications compared changes in word frequency before and after the ChatGPT release on November 30, 2022.

RESULTS

Before ChatGPT's release, the frequency of abstracts with signaling words was 47.1 per 10,000 papers. After the release, this increased to 224.2 per 10,000 papers, an increase of 177.2 per 10,000 papers (p = 0.014, 95 % CI 53.5-300.7). The word 'delve' showed the most significant usage increase (increased ratio=17.0).

CONCLUSIONS

This study is among the first to systematically assess the use of GenAI, specifically ChatGPT, in dental research. We found evidence of the use and growth of ChatGPT in dental research publications. This trend indicates the widespread adoption of GenAI-assisted writing in scientific communication, consistent with other scientific fields. While GenAI can potentially increase productivity and inclusivity, it raises concerns such as bias, inaccuracy, and distortion of academic incentives. Therefore, our findings support the need for clear AI guidelines and standards for academic publishing to ensure responsible use and maintain scientific integrity.

A bibliometric analysis of the research hotspots and frontiers related to cell death in spinal cord injury

Background

Spinal cord injury (SCI) is a severe central nervous trauma that can cause serious consequences. Cell death is emerging as a common pathogenesis after SCI. In the last two decades, numerous studies have been published in the field of cell death after SCI. However, it is still rare to find relevant bibliometric analyses. This bibliometric study aims to visually represent global research trends in the field of cell death after SCI.

Methods

Bibliometric data were sourced from the Web of Science Core Collection (WoSCC) database. VOSviewer, CiteSpace, and R software ("bibliometrix" package) were used to analyze and visualize bibliometric data. Annual scientific production, countries/regions, institutions, authors, journals, highly cited papers, keywords, and literature co-citation were evaluated to determine research performance.

Results

An analysis of 5,078 publications extracted from the WoSCC database revealed a fluctuating yet persistent growth in the field of cell death after SCI over the past 23 years. China and the United States, contributing 69% of the total publications, were the main driving force in this field. The Wenzhou Medical University from China contributed to the most papers. In terms of authors, Salvatore Cuzzocrea from the University of Messina had the highest number of publications. The "Journal of Neurotrauma" was the top journal in terms of the number of publications, however, the "Journal of Neuroscience" was the top journal in terms of the number of citations. The theme of the highly cited articles mainly focused on the mechanism of cell death after SCI. The keyword and literature co-citation analysis mainly focused on the mode of cell death, mechanism research of cell death, and functional recovery after SCI.

Conclusion

This study analyzes the research hotspots, frontiers, and development trends in the field of cell death after SCI, which is important for future studies.

A bibliometric review of biochar for soil carbon sequestration and mitigation from 2001 to 2020

To mitigate global warming and the greenhouse effect, biochar (BC) has been regarded as an important way of carbon sink. Therefore, this research explored the development trend of BC for soil carbon sequestration and mitigation from 2001 to 2020 based on bibliometric analysis. The results show that Yong Sik Ok and Johannes Lehmann are the top 2 high-impact authors. China, America, and Germany are the most widely collaborated countries, but China's research impact is lower than that of America. The Chinese Academy of Sciences has far more publications than any other institution, but Cornell University and Kangwon National University lead the way in terms of impact. Research hotspots can be divided into five clusters: (1) pyrolysis, nutrient, and microbial communities; (2) the immobilization of heavy metals; (3) crop yield and soil properties; (4) greenhouse gas, meta-analysis, and field experiment; (5) carbon fraction and sequestration. Reviews account for 60 % of the top 10 most highly cited papers, and eight of the top 10 focus on the early research period, setting the stage for the development of the BC field. Science of the Total Environment has the highest number of publications and total citations, and literature published in Soil Biology and Biochemistry is to some extent more likely to be cited. In the future, we need to carry out research in the following aspects: (1) Interaction mechanisms between BC, soil, and soil microbial communities. (2) Designing low-cost, high-yield, and high-effect optimization methods to improve the characteristics of BC. (3) Effect of BC on the environment and human health in long-term localization experiments. (4) Carbon sinks of BC need to be further evaluated on a global scale.

Knowledge and attitudes toward evidence-based cariology and restorative dentistry among Egyptian dental practitioners: a cross-sectional survey

BACKGROUND

This is the first study to assess Egyptian dental practitioners' knowledge about conservative caries management approaches and investigate whether this knowledge transfers into clinical practice and the barriers to translating research into evidence-based practice.

METHODS

A sample of dental practitioners was surveyed using an online questionnaire. Convenience and snowball sampling were used to collect data from February to June 2022. We included graduated dentists from Egyptian universities who practiced in Egypt. Data were analyzed with descriptive statistics, and the associations between variables were checked using Kruskal Wallis and Chi-Square tests.

RESULTS

This study included 396 participants from throughout Egypt. There were significant correlations between specialty and participants' knowledge and behaviors toward evidence-based caries management (p = 0.002) and between specialization and tools used to detect carious lesions (p < 0.001). Most participants (59.1%) used G.V Black's classification, and (80.8%) removed caries based on the feature of dentin hardness and color, whereas (67%) removed caries until hard dentine remained. The participants' primary hurdle to staying up-to-date was their belief that the newly gained information would not be clinically applicable due to a lack of equipment or working in low-economic areas. Patient-related barriers were the major obstacles for participants in implementing evidence-based practice.

CONCLUSION

Egyptian dentists did not fully embrace minimal invasive approaches for caries management, and practitioners' experiences continue to shape decision-making. It emphasizes the imperative to practically educate dentists using effective knowledge translation dissemination to promote evidence adoption in daily practice and advocate value-based dental care to address the economic crisis's impact on Egypt's healthcare.

Systematic Reviews in Dental Research: A Bibliometric Analysis of Contribution from Indian Dentists During 1948-2022

AIMS AND OBJECTIVE

Although systematic reviews (SRs) are the backbone of evidence-based dentistry, they have appeared infrequently in dental literature and their importance may not be recognized by dentists. So, this study aimed to identify SRs in dental research contributed by Indian dentists to the PubMed database during 1948-2022 and describes their epidemiological and descriptive characteristics.

MATERIALS AND METHODS

An electronic search of the PubMed database was performed from 1948 through September 2022. SRs were considered for inclusion if they were related to oral health and published by Indian dentists as the first author. From this collection, the following characteristics of SRs were described: name of the journal, type of journal (e.g., general dentistry, specialty dentistry, non-dental), year of publication, author's affiliation, and focus of the SR.

RESULTS

The search identified 439 SRs in dentistry indexed in the PubMed database during 1948-2022. There were only 5 SRs published from 2007 to 2010 with maximum publications during the year 2021 (n = 114; 25.97%). About 32.35% of the SRs (n = 142) were published in 10 journals with the maximum contribution from the Journal of Conservative Dentistry (n = 22; 5.01%). The majority of the SRs were published in the field of Pedodontics and Preventive Dentistry (n = 72; 16.40%), followed by Conservative Dentistry and Endodontics (n = 63; 14.35%).

CONCLUSION

The contribution of SRs in dental research from India is small but growing. There is a clear need to improve SRs in dental research qualitatively and quantitatively.

A Bibliometric Analysis of the International Dental Journal (2011-2020)

INTRODUCTION

Bibliometrics is an area that allows for the evaluation of scientific publications by means of different indicators. The aim of this research was to perform a bibliometric study of the scientific production of the International Dental Journal (IDJ) between 2011 and 2020.

METHODS

All publications of the journal between 2011 and 2020 extracted from the Scopus database were included. The number of publications, most productive institutions, type of collaboration, most productive countries, most cited articles, and authors with the highest academic production were used as bibliographic indicators. It was exported to the SciVal tool for analysis.

RESULTS

A total of 630 documents published in IDJ by 1947 authors were collected, with a total of 7212 citations (11.4 citations per document). The United States was the country with the highest number of documents (100). The University of Adelaide (Australia) was the institution with the highest scientific production (16 publications), whilst the institution with the highest impact was the Universidade de São Paulo (Brazil), with 12.2 citations per paper. Marc Luiz Tennant was the author with the highest number of published manuscripts (13). Finally, most of the publications had international collaboration (146 documents).

CONCLUSIONS

IDJ is a high-quality journal and, in the dental field, it has a high impact worldwide, which allows for a greater number of citations of its articles and placing it in the forefront of future research.

The 100 most-cited articles in orthodontic journals in the last 20 years

INTRODUCTION

This study aimed to identify and analyze the 100 most-cited articles published in orthodontic scientific journals in the past 21 years.

METHODS

The research was conducted in the Thomson Reuters Web of Science data citation index, considering articles from 2000 to 2020 and the category of dentistry, oral surgery, and medicine. Information about the number of citations, citations per year, title, authors, year of publication, the title of scientific journals, type of study, keywords, and thematic field were extracted for each article. Descriptive statistical analyses were performed to evaluate the collected data. The Pearson correlation analysis was used to explore the relationship between publication and the number of citations received. The VOSviewer software (Leiden University Center for Science and Technology Studies, Leiden, the Netherlands) was used to generate the keyword cooccurrence network.

RESULTS

The number of citations of the 100 selected articles ranged from 122 to 547. The journal with the largest number of cited articles was the American Journal of Orthodontics and Dentofacial Orthopedics. Most of the papers were cross-sectional and longitudinal studies, and the most frequent thematic fields among the selected articles were anchorage, root resorption, and rapid maxillary expansion. Orthodontic treatment, anchorage, and root resorption were the most frequent keywords.

CONCLUSIONS

Bibliometric analysis of citations revealed a greater centralization of orthodontic studies. Most of the articles were published in a single journal and by one country. Anchorage is a trending topic in orthodontics, and cross-sectional and longitudinal studies are the most-cited types of papers.

Information-seeking behaviors and barriers to the incorporation of scientific evidence into clinical practice: A survey with Brazilian dentists

The aim of this online cross-sectional study is to identify the sources of scientific information used by Brazilian dentists in clinical decision-making and the barriers that they perceive as important to the incorporation of scientific evidence into clinical practice. A pretested questionnaire created in Google Forms which was made available to participants through links sent by e-mail or shared on Facebook® and Instagram® was used to collect the data between October 2018 and May 2019. Only dentists who were involved in direct or indirect care of patients (i.e. clinicians who performed dental procedures or dental educators who participated in the clinical training of graduate or postgraduate dental students) were asked to complete the questionnaire. The sample was comprised of 528 dentists (the response rate from the alumni database was 6.9%); their mean age was 45.2 years (±12.5) and 30.9% had an academic position. The majority were women (68.0%) and lived in Southern or Southeastern Brazil (96.0%). The sources of scientific information more frequently used by them in clinical decision-making were clinical guidelines (65.1%; 95% CI: 60.9, 69.2), scientific articles (56.8%; 95%CI: 52.5, 61.1) and bibliographic databases (48.3%; 95% CI: 43.9, 52.6). The information resource less frequently used was social media. The most important barriers to the clinical use of scientific evidence were: difficulty in determining whether scientific contents found on the Internet were reliable or not (41.8%; 95% CI: 37.6, 46.2), high cost of access to scientific papers (37.7%; 95% CI: 33.5, 41.9), and lack of time for reading scientific articles (32.4%; 95% CI: 28.4, 36.6). Although Brazilian dentists show a positive attitude towards obtaining scientific evidence from reliable sources, there still remain important barriers to the translation of evidence into practice. This can have significant implications for quality of care and should be further investigated.

The Top 100 Most Cited Articles Published in Dentistry: 2020 Update

This bibliometric review is aimed to analyze the top 100 most-cited publications in dentistry and to compare its outcomes. A literature search was performed using Elsevier's Scopus, without any restriction of language, publication year, or study design. Of 336,381 articles, the top 100 were included based on their citation count, which ranged from 638 to 4728 citations (Feijoo et al., 326 to 2050). The most productive decade was the 2000s, with 40 articles on the list (Feijoo et al., 1980s: 26). Marx RE (7%) was the major contributor in this study (Feijoo et al., Socransky SS: 9%), and almost half (48%) of articles were from the USA. Of the top 100 articles, 26% focused on periodontology (Feijoo et al., periodontology: 43%), while 17% of the total were published in the Journal of Dental Research (Feijoo et al., Journal of Clinical Periodontology: 20%). Most of the publications were narrative reviews/expert opinion (36%), (Feijoo et al., case series: 22%), and were within the evidence level V (64%) (Feijoo et al., 54%). The citation count that a paper secures is not necessarily a reflection of research's quality, however, the current analysis provides the latest citation trends in dentistry.
