The 100 most cited articles in prosthodontic journals: A bibliometric analysis of articles published between 1951 and 2019

STATEMENT OF PROBLEM

Bibliometric studies to determine the characteristics of the most cited articles in prosthodontic journals are lacking.

PURPOSE

The purpose of this study was to analyze the characteristics of the 100 most cited articles in prosthodontic journals between 1951 and 2019.

MATERIAL AND METHODS

The Google Scholar database was used to retrieve the list of journals with titles containing the term "Prosthodontic" or "Prosthetic." Twelve journals were filtered, and of these, only 8 were related to dentistry and hence were included in the study. A search was then performed for each of the selected journals under "Publication Name," and articles were arranged by the category "Times Cited." The 100 most cited articles from the 8 journals were selected and analyzed with regard to journal name, year of publication, authors and their country, type of study, and area of research.

RESULTS

The 100 most cited articles were published between 1958 and 2013, with the numbers of citations ranging between 2368 and 343. The journal with the largest number of the articles cited was the "Journal of Prosthetic Dentistry" with 72 articles, followed by the "International Journal of Prosthodontics" with 25 articles. The decade with most articles published was the 1990s with 33 articles. Many of the authors of most cited articles were from the United States or Sweden. Most articles reported reviews (35 articles), followed by experimental studies (34); the most commonly cited area of research was related to dental implants.

CONCLUSIONS

This bibliometric analysis of the 100 most cited articles revealed interesting facts about scientific progress in the field of prosthodontics.

The 100 Top-Cited Articles Published in Emergency Medicine Journals: A Bibliometric Analysis

Background

The number of citations that an article has received can reflect its importance in a specialty. The purpose of this study was to analyse the characteristics of top-cited articles published in 24 emergency medicine (EM) journals in the Thomson Reuters Web of Science (WoS).

Method

WoS were used to identify the 100 top-cited articles published in EM journals. Basic information, including title, authors, country of origin (based on the first author), institution, publication year, journal name, language, document type, citation times and impact factor, was collected and analysed.

Results

The 100 top-cited articles in EM journals, cited from 175 to 530 times, were published between 1979 and 2010, with most articles published between 2001 and 2005. All articles were written in English, and the United States contributed the most. The articles were distributed in seven different EM journals, led by Annals of Emergency Medicine with 45 articles. Resuscitation medicine was the most discussed topic.

Conclusion

The bibliometric analysis on the 100 top-cited articles in EM journals from WoS demonstrates some significant points, which can have important implications for researchers in evaluating and orienting their research.

Bibliometric analysis of the top-cited articles on islet transplantation

AIMS

To identify and characterize the top-cited articles in the field of islet transplantation.

METHODS

We used the Science Citation Index Expanded database to identify the most frequently cited articles published after 1900. Articles were evaluated using the following characteristics: citation number, publication year, study design, references, country and institution of origin, authorship, and journal. Keyword analysis and citation networks were used to analyze research trends.

RESULTS

The most frequently cited articles received between 146 and 2988 citations; the median was 291. All of the most frequently cited articles were published between 1972 and 2012, and 85 articles were published after 1990. The most popular study design involved basic science (75 articles). The leading countries were the United States (US) and Canada, and the leading institutions were the University of Alberta, Canada, and the University of Minnesota, in the US. Journals specializing in diabetes or transplantation published more than half of the articles (n = 53, 52%), with the journal Diabetes publishing the largest number (n = 30). No association was found between a journal's impact factor and the number of top-cited articles it published. There was no correlation between the number of citations and the number of years since publication, authors, participating institutions, or countries involved. Top-cited articles focused on 2 themes: the use of antirejection immunotherapy or biocompatible encapsulations to prolong graft survival, and assessments of the efficacy of islet transplants, in particular, islet allografts.

CONCLUSIONS

Our study can help researchers to identify and decipher the characteristics of top-cited articles in the field of islet transplantation. Just as clinically successful allografts are carried out using the Edmonton protocol, autografts and xenografts should be similarly strengthened to solve problems relating to immune rejection and islet sources, respectively.

Potential risks of orthodontic therapy: a critical review and conceptual framework

This review examines some of the potential risks of orthodontic therapy along with their evidence base. The risks of orthodontic treatment include periodontal damage, pain, root resorption, tooth devitalization, temporomandibular disorder, caries, speech problems and enamel damage. These risks can be understood to arise from a synergy between treatment and patient factors. In general terms, treatment factors that can influence risk include appliance type, force vectors and duration of treatment whilst relevant patient factors are both biological and behavioural. Hence, the natural variation between orthodontic treatment plans and patients gives rise to variations in risk. A good understanding of these risks is required for clinicians to obtain informed consent before starting treatment as well as to reduce the potential for harm during treatment. After considering each of these risks, a conceptual framework is presented to help clinicians better understand how orthodontic risks arise and may therefore be mitigated.

Top cited articles in urology from Turkey

OBJECTIVE

Citation is the name given for a scientific publication in order to be used as a reference by another publication. In this study, we reviewed the most frequently cited publications in urology from Turkey. Although the number of citations is not completely definitive on its own, it shows the importance and effect of the publication. Besides the number of citations directly determines the impact factor of the journals and this factor is generally used in the evaluation of the quality and importance of the journal.

MATERIAL AND METHODS

On March 7-14, 2016, 51 studies with highest number of citations from Turkey are determined from Science Citation Index Expanded database index and the journals in which studies are published, the authors of the publications, their cities and departments, study types, publication date of the studies and the number of citations are recorded.

RESULTS

The most frequently encountered subjects in the publications that are mostly cited from Turkey are urolithiasis (23.5%), infertility (15.6%), benign prostatic hyperplasia (11.7%), sexual dysfunction (11.7%) and bladder carcinoma/urothelial carcinoma (9.8%). Distribution of 51 publications is as follows: 18 case series, 11 randomized study, 7 non-randomized study, 6 study, 3 review, 3 cross-sectional studies and 3 survey studies. Of all the studies, 68.6% are from Ankara, İstanbul and İzmir and 72.5% of them have originated from the university hospitals.

CONCLUSION

It is important to show the most cited Turkish publications in order to show the contribution in the world literature regarding to urology. The most cited publications in Turkey belong to urolithiasis and andrology areas. When the citation analysis publications in urology and different areas both in Turkey and in the world, it is observed that the number of our qualified publications is at acceptable levels.

Analysis of the 100 most-cited articles in periodontology

AIM

The aim of the present study was to analyze two distinct biomedical electronic databases for the 100 most-cited articles in the field of periodontology.

METHODS

Two electronic databases (Scopus [SCO] and Web of Science [WOS]) were used to retrieve lists of the 100 most-cited articles using appropriately-chosen keywords. The correlation between the number of citations and age of publication was evaluated statistically.

RESULTS

Sixty-three papers could be found in both lists. The mean number of citations in SCO was 476.7 ± 361.9 and 371.2 ± 249.7 in WOS. The mean age of publication in the SCO list was 21.4 ± 9.4 years and 18.6 ± 6.5 years in the WOS list. No correlation was found between age of publication and number of citations for both databases.

CONCLUSIONS

There is a lack of evidence of the correlation between age of publication and number of citations. The concordance between the two databases that were reviewed was relatively significant, even though the rankings of the most-cited articles are dependent on the number of journals covered by one database. The actual value of the number of citations to measure the quality of one article should be carefully evaluated.

This can be used as a potential knowledge base for specialists in training or to produce relevant knowledge defining the direction of future research.

The fifty most cited Italian articles in the orthopaedic literature

PURPOSES

It is widely known that in Orthopaedics, as in each specialty, the academic influence of an article is also determined by the number of times the article is cited. The aim of this study was to identify the 50 most frequently cited Italian orthopaedics journal articles and to analyse the characteristics that might have made them more citable.

METHODS

Science Citation Index Expanded was searched for the 50 most frequently cited Italian orthopaedics journal articles between 1988 and 2013 in the subject category "Orthopaedics".

RESULTS

The 50 most frequently cited articles were all published in English and were published in 12 of the 67 journals in the subject category "Orthopaedics" in the Institute for Scientific Information Web Science (Thomson Reuters, New York, New York, USA). One half of the articles were published before 2000 and the other half later. The number of citations ranged from 423 of the first article (mean citation/years 21.15) to 83 of the fiftieth (mean citation/years 16.60). The articles were all categorized under orthopaedic field, but each of them spanned from orthopaedics to a specific sub-specialty. The majority was clinical articles (n = 39), and the most common fields were sport orthopaedic surgery (including arthroscopy and cartilage) (n = 19) and biomechanics (n = 12).

CONCLUSIONS

This list of 50 most frequently cited Italian articles is, to our knowledge, significantly important for the general orthopaedic scientific community, particularly for the Italian orthopaedic community. Researchers and doctors may use this work to make their future publications more influential and citable.

Exploring the publications in three major orthodontic journals: a comparative analysis of two 5-year periods

OBJECTIVE

To analyze the types of articles and authorship characteristics of three orthodontic journals--American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), The Angle Orthodontist (AO), and European Journal of Orthodontics (EJO)--published between 2008 and 2012 and to assess the differences in content within this period and an earlier period of 1998 to 2002.

MATERIALS AND METHODS

Each journal's content was accessed through the web edition. From each article, the following parameters were recorded: article type, number of authors, number of affiliations, source of article (referring to the first author's affiliation), and geographic origin. Descriptive statistics were performed and selected parameters were analyzed with the Pearson chi-square or Fisher exact test for independence at the .05 level of significance.

RESULTS

Review of differences between the two periods showed that the number of publications was almost double. The percentages of multi-authored articles increased. Fewer studies derived from the United States/Canada and European Union countries. Increases for articles from non-European Union countries, Asia, and other countries were found. Characteristics of the second period showed that the EJO and AO published more research articles, whereas the AJODO regularly published case reports and other articles. Approximately 75% of all studies derived from orthodontic departments.

CONCLUSIONS

The publications from 1998-2002 and 2008-2012 were significantly different both in terms of numbers and characteristics. Within 2008-2012 there were notable differences between the three journals concerning the type and origin of the publications.

The top 100 cited articles in essential tremor

Background

The impact of scientific articles is proportional to the citations they have received. Our aim was to identify and analyze the top 100 cited articles on essential tremor (ET).

Methods

The Institute for Scientific Information Web of Knowledge Database and the 2012 Journal Citation Report Science Editions were used to retrieve the 100 top-cited articles published about ET from 1960 to April 2013. Information was collected by the Analyze Tool on the Web of Science, including number of citations, publication title, journal name, publication year, and country and institution of origin. Additional analyses were then performed to determine authorship, article type, study design, and level of evidence.

Results

Almost half of the articles were retrieved from two journals: Neurology (n = 31) and Movement Disorders (n = 18). The top 100 articles were published between 1960 and 2010, with case series being the most common study design (n = 34). According to their countries of origin, more than half of the articles were generated in the United States (n = 54), which led the list. Columbia University in the United States produced the largest number of ET articles (n = 19), followed by the University of Kansas (n = 18). The most frequent first authors of the top-cited articles in ET were E.D. Louis (n = 27) and W.C. Koller (n = 15), who together accounted for 42% of the articles on the list.

Discussion

It is important to acknowledge the top-cited articles as they mark key topics and advances in ET.
