Predictors of societal and professional impact of Endodontology research articles. A multivariate scientometric analysis

Does Reader Engagement with Neurosurgery Journal Websites Correlate with the Number of Citations Received by Articles?

BACKGROUND

Medicine has begun adapting to new information-sharing paradigms in the hyper-connected social media era. In this milieu, the role of journal websites in the dissemination of clinical and research information needs to be reevaluated.

OBJECTIVE

We sought to explore whether reader engagement with neurosurgical journal websites, reflected by the number of article views and downloads, correlated with the eventual number of citations received by the articles.

METHODS

The websites of all Medline indexed neurosurgical journals were screened to identify those that provided information regarding the number of abstract and full text views and downloads. Articles published in these journals between July 2010 and June 2011 were included in this analysis. Various article attributes were identified and the number of citations per article was obtained from Google Scholar. The impact factors of the selected journals for the year 2010 were obtained from the Journal Citation Reports.

RESULTS

Twenty-two journals that had published 2527 articles were finally included in this analysis. The number of abstract views, full-text views, and downloads all correlated strongly with the journal impact factors in 2010 as well as the eventual citations per article. The number of article downloads independently predicted the citations per article on multivariate analysis. Neurology India had significantly higher article views and downloads but lower citations per article than the other journals.

CONCLUSIONS

Readers were found to engage significantly with neurosurgical journal websites and therefore, open access to articles would lead to increased visibility of articles, resulting in higher citation rates.

Factors associated with scientific production citations in dentistry: Zero-inflated negative binomial regression and hurdle modelling

Background: The global scientific literature in dentistry has shown important advances in the field, with major contributions ranging from the analysis of the basic epidemiological aspects of prevention to specialised results in the field of dental treatments. The present investigation aimed to analyse the current state of the scientific literature on dentistry hosted in the Web of Science database. Methods: The methodology included two phases in the analysis of articles and indexed reviews in all thematic areas. During the first phase, the following variables were analysed: scientific production by the publisher, the evolution of scientific output published by publishers, the factors associated with the impact of scientific production, and the modelling of the impact of scientific production on dentistry. During the second phase, associations, evolutions, and trends in the use of keywords in the scientific literature in dentistry were analysed. Results: The first phase shows that scientific production in dentistry will increase between 2010 and 2021, reaching 12,126 articles in 2021. Publishers such as Wiley and Elsevier stand out, but Quintessence Publishing has the most citations. Factors such as pages, authors, and references influence the number of citations. Phase 2 analyzes trends in the dental literature using the WoS database. Topics such as "dental education", "pediatric dentistry", and "pandemic" stand out. The intersection of technology and dentistry and the importance of evidence-based education are highlighted. Conclusions: In conclusion, the study shows that the most studied topics include the association of dental education and the curriculum, the association of pediatric dentistry with oral health, and dental care. The findings show that more recently emphasised topics also stand out, such as evidence-based dentistry, the COVID-19 pandemic, infection control, and endodontics, as well as the need for future research to expand current knowledge based on emerging topics in the scientific literature on dentistry.

Mapping out the bibliometric characteristics of classic articles published in a Taiwanese academic journal in dentistry: A scopus-based analysis

Background/purpose

Since its inception, the Journal of Dental Sciences (JDS) has aimed to publish quality articles relevant to all fields in dentistry. The purpose of this study was to analyze the bibliometric characteristics and dissected associated factors correlated with citation counts of classic articles published in the JDS.

Materials and method

Scopus® database was used to search the qualified articles published in JDS from 2009 to 2021. The bibliometric parameters, including journal impact factor (JIF), self-citation, study design, research field, geographic, country and institute of origin, inter-institute, inter-nation collaboration, keywords hotness and associated factors correlated with citation counts of classic articles were analyzed.

Results

One hundred and eight articles from Scopus® database were eligible for analysis. The citation counts of classic articles ranged from 12 to 192, the average citation was 22.02. The most common study design was the in vitro/in vivo, followed by the cross-sectional study, and the major research field were Dental Materials. The most productive country and institute is Taiwan, and Chung Shan Medical University, respectively. The trend of inter-institute (71.03%) and inter-nation (11.22%) collaboration steadily increased since 2009. By using the multivariable linear regression model, Preventive and Community Dentistry in the research field significantly increased the citation counts.

Conclusion

Despite its limitations, the escalating trends in JIFs, and JIFs without self-citations, and inter-nation and inter-institute collaboration of classic articles were noticed. Of all the dissected associated factors, Preventive and Community Dentistry in the research field significantly increased the citation counts of classic article.

Supporting grant reviewers through the scientometric ranking of applicants

INTRODUCTION

Comparing the scientific output of different researchers applying for a grant is a tedious work. In Hungary, to help reviewers to rapidly rank the scientific productivity of a researcher, a grant decision support tool was established and is available at www.scientometrics.org. In the present study, our goal was to assess the impact of this decision support tool on grant review procedures.

METHODS

The established, publicly available scientometric portal uses four metrics, including the H-index, the yearly citations without self-citations, the number of publications in the last five years, and the number of highly cited publications of a researcher within eleven independent scientific disciplines. Publication-age matched researchers are then ranked and the results are provided to grant reviewers. A questionnaire was completed by reviewers regarding utilization of the scientometric ranking system. The outcome of the grant selection was analyzed by comparing scientometric parameters of applying and funded applicants. We compared three grant allocation rounds before to two grant allocation rounds after the introduction of the portal.

RESULTS

The scientometric decision support tool was introduced in 2020 to assist grant selection in Hungary and all basic research grant applicants (n = 6,662) were screened. The average score of funded proposals compared to submitted proposals increased by 94% after the introduction of the ranking. Correlation between ranking scores and actual grant selection was strong in life and material sciences but some scientific panels had opposite correlation in social sciences and humanities. When comparing selection outcome to H-index across all applicants, both type I and type II errors decreased. All together 540 reviewers provided feedback representing all eleven scientific disciplines and 83.05% of the reviewers (especially younger reviewers) found the ranking useful.

CONCLUSIONS

The scientometric decision support tool can save time and increase transparency of grant review processes. The majority of reviewers found the ranking-based scientometric analysis useful when assessing the publication performance of an applicant.

Scientific production on silicate-based endodontic materials: evolution and current state: a bibliometric analysis

OBJECTIVES

To perform a bibliometric analysis on silicate-based biomaterials in endodontics; to elucidate the evolution and distribution of scientific production regarding research on these biomaterials, the authors and institutions involved, and the most used descriptors/keywords in this field.

MATERIALS AND METHODS

A general advanced broad search was performed in Web of Science Core Collection, using the terms "Silicate" and "Endod*." By means of the "Analyze Results" and "Citation Analysis" tools from Web of Science, bibliometric data were extracted. Bibliometric networks on co-authorship and keyword co-occurrence were illustrated using VOSviewer software tool.

RESULTS

Research in the field of silicate-based endodontic materials in endodontics has followed an exponential crescent tendency over the period between 1995 and 2020. Two major co-authorship networks lead the research production in the field, headed by Gandolfi MG and Prati C, and Rodríguez-Lozano FJ and Forner L; respectively. "Mineral trioxide aggregate," "MTA", "Biocompatibility," "Biodentine," and "In vitro" were the terms with the highest occurrence. The modal study type in this research area are laboratory studies, representing 77.7% of the total number of records. The relationship between keywords illustrates the recent tendency to assess biological properties of MTA and Biodentine, which could be extrapolated to other silicate-based materials.

CONCLUSIONS

The results from the present study highlight the exponential increase and distribution of scientific production on silicate-based materials in endodontics, along with the modal keywords used as descriptors and the major authorship networks involved. The predominance of laboratory studies in this research field reinforces the need for clinical studies, to extrapolate the reported performance and characteristics of silicate-based materials into the clinical setting.

CLINICAL RELEVANCE

The present study may aid the clinician's continuing education and evidence-based practice by providing knowledge and facilitating the literature search on the field of silicate-based biomaterials in endodontics.
