Abstract
This study analyzes the characteristics of the top-100 most cited articles published in international dental journals with at least one coauthor affiliated to Brazil. A search in Scopus database for articles published between 1996 and 2017 was carried out in the 178 journals belonging to the category "Dentistry" identified in SCImago Journals & Country Rank. From the top-100 most cited articles, variables related to the journal, article, and authors were collected. Annual citation averages (ACA) and relative citation ratios (RCR) were calculated. Data were analyzed descriptively. There were 75 original reports and 25 reviews in the sample. The number of citations ranged between 124 and 657 (mean=202, median=168). The papers were published in 31 different journals (46% in only four journals), none based in Brazil. The most frequent subjects (61%) were Dental Materials, Endodontics, and Periodontology, which accounted for 63.6% of the total citations. The subject with the highest ACA was Oral and Maxillofacial Surgery and the subject with the highest RCR was Oral Radiology. Only 12 articles were cited more than 300 times. International collaboration was present in 61 articles and funding was reported in 49 articles. The first author was from Brazil in 70% and corresponding author in 55% of the papers. Southeast (83%) and South (20%) were the regions of Brazil with most presence of coauthors. This top-100 list is presented to provide an overview of the most cited articles and aid in supporting further analyses regarding publication and citation behaviors of Brazilian dentistry.
Highlights
Bibliometric studies apply mathematics and statistics to quantitatively evaluate the scientific literature in many different ways and for a varied of purposes (1)
Many bibliometric tools were developed in the last decades, most considering the number of citations received by an article in a given database and timeframe
Search Strategy and Eligibility Criteria In this cross-sectional study, the 178 journals belonging to the category “Dentistry” that were identified in SCImago Journals & Country Rank, which is powered by the Scopus database, were investigated
Summary
Bibliometric studies apply mathematics and statistics to quantitatively evaluate the scientific literature in many different ways and for a varied of purposes (1). Many bibliometric tools were developed in the last decades, most considering the number of citations received by an article in a given database and timeframe. Research supporting agencies use citation rates and other publication metrics to evaluate budgetary spending and distribute financial resources (4). It has been debated whether the number of citations received by an article may reflect or not its actual influence in the literature or whether it is a fair appraisal since it does not represent the whole complexity of the research work (5,6). Other scientific indicators consider the absolute number of citations and the length of time that an article has been available to possible citers (7) or the number of articles published in a given timeframe (8,9). In 2017, a total of 1,876 dental citable documents were published in Scopus database with coauthor(s) based in Brazil
