Aim\ud \ud To identify and analyse the main features of the top 100 most‐cited randomized controlled trials, systematic reviews and meta‐analyses published in endodontic journals from 1961 to 2018.\ud \ud \ud Methodology\ud \ud The Clarivate Analytics’ Web of Science ‘All Databases’ was used to search and analyse the 100 most frequently cited randomized controlled trials, systematic reviews and meta‐analyses having ‘randomized’, ‘randomised’, ‘randomized controlled’, ‘randomised controlled’, ‘randomized controlled trial’, ‘randomized controlled trials’, ‘clinical trial’, ‘systematic’, ‘systematic review’, ‘meta‐analysis’, and ‘meta‐analyses’ in the title section. The ‘International Endodontic Journal’, ‘Journal of Endodontics’, ‘Oral Surgery Oral Medicine Oral Pathology Oral Radiology and Endodontology’, ‘Australian Endodontic Journal’, ‘Endodontics & Dental Traumatology’, ‘Endo‐Endodontic Practice Today’ and ‘European Endodontic Journal’ were included in the publication name section. After ranking the articles in a descending order based on their citation counts, each article was cross‐matched with the citation counts in Elsevier's Scopus and Google Scholar. The articles were analysed, and information on citation counts, citation density, year of publication, contributing authors, institutions and countries, journal of publication, study design, topic of the article and keywords was extracted.\ud \ud \ud Results\ud \ud The citation counts of the 100 most‐cited articles varied from 235 to 20 (Web of Science), 276 to 17 (Scopus) and 696 to 1 (Google Scholar). The year in which the top 100 articles were published was 2010 (n = 13). Among 373 authors, the greatest number of articles was associated with three individuals namely Reader A (n = 5), Beck M (n = 5) and Kvist T (n = 5). Most of the articles originated from the United States (n = 24) with the greatest contribution from Ohio State University (USA) (n = 5). Randomized controlled trials were the most frequent study design (n = 45) followed by systematic reviews (n = 30) with outcome studies of root canal treatment being the major topic (n = 35). The Journal of Endodontics published the largest number of included articles (n = 70) followed by the International Endodontic Journal (n = 27). Among 259 unique keywords, meta‐analysis (n = 23) and systematic review (n = 23) were the most frequently used. \ud \ud \ud Conclusion\ud \ud This study has revealed that year of publication had no obvious impact on citation count. The bibliometric analysis highlighted the quantity and quality of research, and the evolution of scientific advancements made in the field of Endodontology over time. Articles before 1996, that is prior to the CONSORT statement that encouraged authors to include specific terms in the title and keywords, may not have been included in this electronic search.

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 342. 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 (36 articles), followed by experimental studies (35); 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.

An examination of top-cited articles is a tool that can be used to identify and monitor outstanding scientific research. The goal of this study was to identify and analyze the characteristics of the 100 top-cited articles published in international journals dedicated to psychiatry. The Science Citation Index Expanded provided by the Thomson Reuters Institute for Scientific Information Web of Knowledge was searched in December, 2011, and 128 journals were identified in the subject category "Psychiatry." Each journal was searched on the Web of Science under "Publication Name" and the results were sorted by category "Times Cited." The 100 top-cited articles were recorded, and the list was analyzed with regard to journals, number of citations, authors, year, institution, and country of origin. The original research articles of the 100 top-cited articles were classified into one of five categories: scale/measurement, descriptive/epidemiology, mechanism, management, and imaging. The 100 top-cited articles were cited between 26,578 and 781 times; they were published between 1957 and 2005, with the largest number (35) published in the 1990s. The articles appeared in 24 journals, with more than half published in the Archives of General Psychiatry (56), followed by the American Journal of Psychiatry (6), and Psychological Medicine (6). Articles that dealt with the development, application, or validity of measurements led the list of top-cited psychiatric publications (43) and had a significantly higher number of citations compared with the rest of the articles. The time and language of publication, field of study, country of origin, and journal in which the paper appeared are possible determinants of the likelihood of citation and impact.

The media affects individuals' behaviors, especially by means of news and advertisements. In this study, we evaluated health content of organ donation and transplantation news in the printed media and on television programs for a 1-year period in Turkey. We examined 2449 news items in 230 newspapers and magazines; 1179 news programs on 45 television channels, all concerning organ donation and transplantation. The news obtained from the Media Pursuit Center were transferred to an electronic file to evaluate the format and content of the news. Nine variables were examined about the scope and the formal characteristics of the news: the publication name, its type, the province, the date, the headline, the title length, the presence of a photograph, or its kind, the news size, and the page number. In the content analysis of the news, we also examined 9 variables: the topic, the message of the headline, the property of the words in the title, the identification of photographs in the news, the age, gender of actors in the news, as well as donor or recipient. In a summary, print media and television channels, failed to show sufficient information about organ donation and transplantation. The percentage of news about organ donation and transplantation was small and mostly negative items in the media. On television channels, sufficient place was not given to organ donation and transplantation. The news in printed media and on television channels was not about motivated or altruistic behavior. The pattern of organ donation and transplantation news is important in terms of perception and comment by the public. Furthermore it directly affects the perception of the news by the reader.
