Saudi Dent J 2023; 35:812-818. [PMID: 38025592 PMCID: PMC10658367 DOI: 10.1016/j.sdentj.2023.06.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 06/16/2023] [Accepted: 06/17/2023] [Indexed: 12/01/2023] Open
Abstract
Objectives The Level of Evidence (LOE) ranking system is used to measure the methodological quality of research. This study aimed to analyze and evaluate the trends of LOEs in articles published in the Saudi Dental Journal (SDJ) between 2012 and 2021. Methodology The bibliometric details of all articles published from 2012 to 2021 were extracted from the SDJ website. All articles, expect editorials, were included in the analysis. The articles were divided based on LOEs, dental specialties, number of authors, and centers. The citation metrics were obtained from Google Scholar, and the statistical analysis was performed using JMP Pro 15.2.0 software. Results Five hundred twenty-two articles were selected for analysis. They had an average of 21.19 citations per article, and a growing trend in the number of articles was observed. Authors from 40 countries contributed to the articles, with the most contributions from the Kingdom of Saudi Arabia. Most articles (n = 269; 51.53%) were LOE IV and V, while a low proportion (5.56%) were LOE I articles. Aside from miscellaneous articles, periodontics composed most of the LOE I studies, followed by endodontics, and oral and maxillofacial Surgery (OMFS). Orthodontics had the highest number of LOE II studies, pediatric dentistry had the most LOE IV, and prosthodontics had the most LOE V studies. No significant correlations were found between LOE and the number of authors or centers. However, a significant correlation was found in the distribution of LOE contributed by academic institutes. Conclusion The study results highlight that most articles were LOE IV and V, whereas nominal LOE I articles were found. Furthermore, there is a need to encourage dental scientists to carry out high-quality evidence studies. Professional dental societies can play a pivotal role in this regard.

Yu X, Chen Y, Li Y, Hong J, Hua F. A Bibliometric Mapping Study of the Literature on Oral Health-related Quality of Life. J Evid Based Dent Pract 2023; 23:101780. [PMID: 36707159 DOI: 10.1016/j.jebdp.2022.101780] [Citation(s) in RCA: 19] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Revised: 08/10/2022] [Accepted: 08/29/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Oral health is an indispensable component of overall health, and oral health status significantly influences people's physical, mental, and social well-being. Oral health-related quality of life (OHRQoL), an important and widely used dental patient-reported outcome (dPRO), is attracting more and more researchers' attention and interest. This study aimed to analyze and map the existing scientific literature regarding OHRQoL through a bibliometric approach, including a summary of the characteristics of OHRQoL-related publications, the identification of prolific entities, high-frequency keywords analysis, and research trend analysis via periodic high-impact keywords. METHODS A literature search was conducted in the Web of Science Core Collection to collect OHRQoL-related original research and review articles. After examination and deduplication, the following bibliometric information was extracted from each article: title, abstract, keywords, authors, affiliations, geographic origin (countries/regions), year of publication, journal name, and references. Various scientometric mapping tools including Microsoft Office spreadsheet, VOSviewer, Biblioshiny R-package software, and Scimago Graphica were used to analyze basic bibliometric parameters, leading producers, high-impact keywords, and research trends. RESULTS A total of 3324 OHRQoL-related articles (3119 original research articles and 205 review papers) were collected, which received 65,704 citations. A total of 9950 authors from 2429 organizations contributed to this body of research. Prolific authors from Europe, USA, Brazil, New Zealand, China, and Canada were identified, and they also centered collaboration clusters in the co-author network. Community Dentistry and Oral Epidemiology was the most prolific journal. Twenty-one keywords with more than 200 occurrences, and 23 keywords with more than 150 occurrences, were identified for publications of 1994-2021 and 2012-2021, respectively. Keyword analysis revealed hot topics such as instrument development and validation, studies targeting children and adolescents, as well as clinical studies in operative dentistry, implantology, orthodontics, and community dentistry. Oral Health Impact Profile is the most commonly used instrument in OHRQoL-related research. CONCLUSIONS OHRQoL is an impactful topic in dental health care as it is not only useful in dental research and patient-centered clinical outcome measures but also provides valuable guidance in dental public health administration and policy making. OHRQoL-related research presents a dynamic landscape and is expected to continue presenting high productivity and broad application in the future.

Doğramaci EJ, Rossi-Fedele G. Predictors of societal and professional impact of Endodontology research articles. A multivariate scientometric analysis. Int Endod J 2021; 55:312-325. [PMID: 34958490 DOI: 10.1111/iej.13676] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Accepted: 12/26/2021] [Indexed: 11/30/2022]
Abstract
AIM To identify factors that are predictive of short-term professional and societal impact of research within the specialty of Endodontology, and to identify the top-10 articles that achieved the greatest societal impact and describe their characteristics. METHODOLOGY Research articles in the field of Endodontology published in 2019 were eligible for inclusion, with the sample identified using Medline. Following screening of titles and abstracts, bibliometric data of the identified articles were exported into a spreadsheet, where further data related to continental origin, type of article, type of journal (endodontic or non-endodontic) and grant-funding were collated, with additional data concerning presence of journal impact factor, citations, news mentions and Altmetric-tracked-mentions and scores compiled using Clarivate, Scopus, ProQuest and Altmetric Explorer, respectively. Data analysis comprised descriptive statistics, frequency distributions, cross-tabulations and un/adjusted negative binomial regression models (P<0.05). RESULTS The search retrieved 30,443 articles; 951 were included for analysis. Most articles originated from Asia (43.2%) with over 51.5% of articles published in endodontic journals and 80% published in a journal with an impact factor. Over three-quarters of articles were primary research, 141 were grant-funded, 165 had a news mention, 338 achieved an Altmetric Attention Score and 808 were cited. The five-highest ranked articles were mentioned in general news bulletins, five of the top-10 articles were primary research and six of the top-10 were published in endodontic journals. The highest Altmetric Attention Score and citation count were 100 and 87, respectively. Adjusted models demonstrated that the type of article, publication in a journal with an impact factor, absence of grant-funding and coverage within general news bulletins predicted the Altmetric Attention Scores (P<0.001). Article type, publication in an impact-factor journal and presence of an Altmetric Attention Score were predictive of citations (P<0.001). CONCLUSIONS Article type and publication in a journal with an impact factor were significant predictors of both societal and professional impact of research articles within Endodontology in the short-term. Non grant-funded research and coverage in general news bulletins achieved greater societal impact, whereas an article achieving an Altmetric Attention Score was also strongly related to professional impact.

Abstract
AIM To identify the top 100 most-cited case reports and case series published in Endodontic journals and to analyse their bibliometric characteristics. METHODOLOGY The Clarivate Analytics' Web of Science (WoS), Scopus and PubMed databases were used to identify the top 100 most-cited case reports and case series in Endodontic journals. Complete bibliographic records of the selected case reports and case series were exported in plain text or BibTeX format and imported into the R environment for statistical computing and graphics. The following parameters were then analysed: names and affiliations of the authors, title, year of publication, journal of publication, first author, corresponding author, literature cited within reports, language, citation counts, impact factor of the journal, keywords, Keywords Plus and research topic. RESULTS In total, 88 case reports and 12 case series published in English between 1977 and 2016 were identified as the most-cited reports in the field of Endodontics. The terms "case report(s)" or "case series" were not included in the title of 57 articles. The number of authors per report ranged from one to seven, with the average number of co-authors per report being 3.14. The most-cited author was M Trope (University of Pennsylvania, USA). The University of Washington and Private Practice, Cetraro, Italy, were the most productive institutions. The country whose case reports received the largest total number of citations was the United States. The largest number of the most-cited reports appeared in 2002, 2004 and 2007 (n = 7, respectively). According to the WoS database, the total number of citations ranged from 42 to 453, with the average number of citations per report being 79.97. The majority of the top 100 most-cited articles were published in the Journal of Endodontics and the International Endodontic Journal. The most frequently used author keywords were revascularization and mineral trioxide aggregate. The majority of the case reports and case series dealt with topics related to pulp regeneration. CONCLUSION This bibliometric study provides a comprehensive overview on the progress, trends and current directions in clinical practice within the field of Endodontics.

Root Canal Disinfection Articles with the Highest Relative Citation Ratios. A Bibliometric Analysis from 1990 to 2019. Antibiotics (Basel) 2021; 10:antibiotics10111412. [PMID: 34827350 PMCID: PMC8614753 DOI: 10.3390/antibiotics10111412] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 11/11/2021] [Accepted: 11/15/2021] [Indexed: 11/30/2022] Open
Abstract
The relative citation rate (RCR) is a normalized article-level metric useful to assess the impact of research articles. The objective of this bibliometric study is to identify and analyze, in root canal disinfection, the 100 articles having the highest RCRs in the period 1990–2019, then compare them with the top 100 articles most cited. A cross-sectional study was performed, and the search strategy ((Disinfection AND root canal) AND ((“1990/01/01”[Date-Publication]: “2019/12/31”[Date-Publication]))) relied on PubMed (n = 4294 documents), and article data were downloaded from the iCite database. The 100 articles with the highest RCRs and the top 100 cited were selected and evaluated in bibliometric terms. Among the 100 articles with the highest RCRs, there were no differences in the three decades for RCRs values, but there were in citations, being 2000–2009 the most cited. The USA was the predominant country (n = 30), followed by Brazil (n = 14). The most frequent study designs were reviews (n = 27) and in vitro (n = 25) and ex vivo (n = 24) studies. All subfields were well represented, although they varied over time. In 2010–2019, regenerative procedures and irrigation/disinfection techniques were predominant. Considering the RCR’s top 100 articles, 76 were common with the 100 most cited articles. Using the RCR metric allowed us to identify influential articles in root canal disinfection, a research field with topics of significance that fluctuate over time. Compared to citations, RCR reduces the time from publication to detection of its importance for the readership and could be a valid alternative to citation counts.

Abstract
INTRODUCTION Bibliographic analysis using quantitative measurements such as citation number and citation density is a common method used to evaluate the impact of previously published studies on current research. Several bibliographic endodontic studies ranking publications based on their number of citations have been published. However, to date, a focus on the most cited articles related to the outcome of endodontic treatment is lacking. The purpose of this study was to identify the most cited publications and their citation density as related to the outcome of nonsurgical root canal treatment (NSRCT), nonsurgical root canal retreatment (NSRCR), and root canal surgery (RCS). METHODS A search of all citations regarding the outcome of NSRCT, NSRCR, and RCS was performed using the Web of Science platform. The search included key words covering all relevant categories. Only publications in the English language published between May 1960 and July 2021 were included. The publications were divided into the following groups: NSRCT, NSRCR, and RCS. Each group was further subdivided into experimentation studies and review studies. The publications were analyzed and sorted in descending order according to the number of citations that each publication has received. Only publications with 100 citations or more were included. Citation density was also assessed. RESULTS The total number of NSRCT citations found was 257; 221 (86%) were experimentation studies, and 36 (14%) were review studies. Of the 221 NSRCT experimentation studies, 41 (18.55%) had 100 citations or more. Of the 36 NSRCT review studies, 9 (25%) had 100 citations or more. The total number of NSRCR citations found was 61; 51 (83.6%) were experimentation studies, and 10 (16.4%) were review studies. Of the 51 NSRCR experimentation studies, 5 (9.8%) had 100 citations or more. Of the 10 NSRCR review studies, 2 (20%) had 100 citations or more. The total number of RCS citations found was 119; 90 (75.6%) were experimentation studies, and 29 (24.4%) were review studies. Of the 90 RCS experimentation studies, 11 (12.2%) had 100 citations or more. Of the 29 RCS review studies, 2 (6.9%) had 100 citations or more. In total, 70 publications on the outcome of endodontic treatment had 100 or more citations. Fifty publications (71.4%) pertained to the NSRCT groups, 7 publications (10%) to the NSRCR groups, and 13 publications (18.6%) to the RCS groups. CONCLUSIONS Bibliographic analysis is a beneficial aid for assessing the impact of publications studying the outcome of endodontic treatment on the field of endodontics.

Abstract
Objectives This study aimed to analyze the main features of the 25 most-cited articles in minimally invasive access cavities. Materials and Methods An electronic search was conducted on the Clarivate Analytics' Web of Science ‘All Databases’ to identify the most-cited articles related to this topic. Citation counts were cross-matched with data from Elsevier's Scopus and Google Scholar. Information about authors, contributing institutions and countries, year and journal of publication, study design and topic, access cavity, and keywords were analyzed. Results The top 25 most-cited articles received a total of 572 (Web of Science), 1,160 (Google Scholar) and 631 (Scopus) citations. It was observed a positive significant association between the number of citations and age of publication (r = 0.6907, p < 0.0001); however, there was no significant association regarding citation density and age of publication (r = −0.2631, p = 0.2038). The Journal of Endodontics made the highest contribution (n = 15, 60%). The United States had the largest number of publications (n = 7) followed by Brazil (n = 4), with the most contributions from the University of Tennessee and Grande Rio University (n = 3), respectively. The highest number of most-cited articles were ex vivo studies (n = 16), and ‘fracture resistance’ was the major topic studied (n = 10). Conclusions This study revealed a growing interest for researchers in the field of minimally invasive access cavities. Future trends are focused on the expansion of collaborative networks and the conduction of laboratory studies on under-investigated parameters.

Abstract
INTRODUCTION Research on clear aligner treatment (CAT) has increased in recent years. In this study, we aimed to perform a bibliometric and visualized analysis to identify and critically assess the 50 most highly cited articles on CAT. METHODS Web of Science was selected as a data source and consulted until March 2020 to identify all articles potentially relevant to the analysis. All the eligible articles were collected until 50 manuscripts were listed. Article-based parameters, journal-based parameters, and author-based parameters were registered to perform the bibliometric analysis. Keywords were automatically harvested from the selected articles to implement the visualized analysis. RESULTS The search identified a total of 378 articles; the total number of citations of the selected articles varied from 15 to 112. The average number of citations per year varied from 1.15 to 13.83. The predominant study design was clinical (31.7%). Over the 15 journals in which the most cited articles were published, the American Journal of Orthodontics and Dentofacial Orthopedics published the majority of those included in the list (14) and also received the greatest number of citations (671). A total of 195 authors contributed to the 50 most cited articles; a significant portion of them (26) were unaffiliated with academic institutions. A total of 184 keywords were gathered from the article list. CONCLUSIONS The number of citations on CAT is expected to grow steadily in parallel with the rising number of research projects. The present work identifies the most influential articles on CAT and their characteristics, placing emphasis on the journals, the authors, and the topics addressed.

Medicine (Baltimore) 2020; 99:e22885. [PMID: 33126338 PMCID: PMC7598835 DOI: 10.1097/md.0000000000022885] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Publications regarding the 100 top-cited articles in a given discipline are common, but studies reporting the association between article topics and their citations are lacking. Whether or not reviews and original articles have a higher impact factor than case reports is a point for verification in this study. In addition, article topics that can be used for predicting citations have not been analyzed. Thus, this study aims to METHODS:: We searched PubMed Central and downloaded 100 top-cited abstracts in the journal Medicine (Baltimore) since 2011. Four article types and 7 topic categories (denoted by MeSH terms) were extracted from abstracts. Contributors to these 100 top-cited articles were analyzed. Social network analysis and Sankey diagram analysis were performed to identify influential article types and topic categories. MeSH terms were applied to predict the number of article citations. We then examined the prediction power with the correlation coefficients between MeSH weights and article citations. RESULTS The citation counts for the 100 articles ranged from 24 to 127, with an average of 39.1 citations. The most frequent article types were journal articles (82%) and comparative studies (10%), and the most frequent topics were epidemiology (48%) and blood and immunology (36%). The most productive countries were the United States (24%) and China (23%). The most cited article (PDID = 27258521) with a count of 135 was written by Dr Shang from Shandong Provincial Hospital Affiliated to Shandong University (China) in 2016. MeSH terms were evident in the prediction power of the number of article citations (correlation coefficients = 0.49, t = 5.62). CONCLUSION The breakthrough was made by developing dashboards showing the overall concept of the 100 top-cited articles using the Sankey diagram. MeSH terms can be used for predicting article citations. Analyzing the 100 top-cited articles could help future academic pursuits and applications in other academic disciplines.

[PMID: 33081141 PMCID: PMC7587529 DOI: 10.3390/molecules25204747] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2020] [Revised: 10/10/2020] [Accepted: 10/10/2020] [Indexed: 12/28/2022] Open
Abstract
The objective of this study was to evaluate the publications in the field of dentistry on the PubMed database over a span of 10 years, from 2009 to 2019. Articles published between January 2009 to December 2019 were searched for in the MEDLINE database via PubMed. Data analysis was done using R-base packages, including the specialized R-packages Bibliometrix and String. For descriptive statistics and sequence charting, SPSS version 23.0 was used. A total of 104,975 articles were extracted, with a total of 153,530 authors in the given time frame. The proportion of articles steadily increased from 2009, plateauing at its peak from 2010 to 2016, and then seeing a decline from 2017 to 2019. Journal articles (60.58%), comparative studies (16.05%) and case reports (10.8%) were recorded as the most reported type of publication globally, accounting for 81.43% of the total documents extracted. All the articles came from 81 countries, with the USA reporting the greatest number of published articles (45,911). Dentistry proves to be a multi-faceted arena and many researchers and authors around the globe are contributing to the burgeoning literature over time.
