The top 100 most-cited clinical trials and systematic reviews related to children and adolescents' oral health: A bibliometric analysis / Os 100 ensaios clínicos e revisões sistemáticas mais citados relacionados à saúde bucal de crianças e adolescentes: uma análise bibliométrica

Aim: To identify and analyze the 100 most-cited clinical trials (CTs) and systematic reviews (SRs) related to children and adolescents' oral health. Methods: A search was conducted in the Web of Science Core Collection (WoS-CC), using a specific search strategy. Papers were ranked in descending order, considering number of citations. Only CTs and SRs were considered. Two reviewers selected the papers and collected the bibliometric data: year of publication; number and density of citations; study designs; journals; authors; countries and institutions; topics of study; and keywords. Poisson regression was performed to verify associations between the number of citations and bibliometric parameters. Results: The 100 most-cited papers were published between 1982 and 2018 and received a total of 8,702 citations in the WoS-CC (ranging from 52 to 177). Fifty-three papers were CTs and 47 SRs. The American Journal of Orthodontics and Dentofacial Orthopedics published the most papers (n=20). Twetman S contributed the highest number of papers (n=7). The United States of America was the most prolific country (n = 17), followed by the Netherlands (n=11). The University of Nijmegen (Netherlands) presented 8 papers among the most-cited. The main topic of interest was Cariology (n = 40). "Dental Caries" was the most frequent keyword (n = 20). The citations' number from WoS-CC decreased by 1.3% each year (RP: 0.987, 95%CI: 0.975­1.000, p = 0.048). Conclusion: This bibliometric study allowed an analysis of the most-cited CTs and SRs related to children and adolescents' oral health, highlighting the most prolific authors, institutions and countries based on the number of citations.

Objetivo:Esta revisão analisou os 100 ensaios clínicos (EC) e revisões sistemáticas (RS) mais citados relacionados à saúde bucal de crianças e adolescentes. Métodos: Realizou-se uma busca na base de dados Web of Science Core Collection (WoS-CC), utilizando uma estratégia de busca específica. Os artigos foram classificados em ordem decrescente, considerando o número de citações. Foram incluídos apenas ECs e RSs. Dois revisores selecionaram os artigos e coletaram os seguintes dados bibliométricos: ano de publicação; número e densidade de citações; desenhos de estudo; periódico; autores; países e instituições; tópicos de estudo; e palavras-chave. Regressão de Poisson foi conduzida para verificar associações entre o número de citações e os parâmetros bibliométricos.Resultados: Os 100 artigos mais citados foram publicados entre 1982 e 2018 e receberam um total de 8.702 citações na WoS-CC (variando de 52 a 177). Cinquenta e três artigos eram ECs e 47 RSs. O American Journal of Orthodontics and Dentofacial Orthopaedics publicou a maioria dos artigos (n = 20). Twetman S contribuiu com o maior número de artigos (n = 7). Os Estados Unidos da América foram o país mais prolífico (n = 17), seguido pelos Países Baixos (n = 11). A Universidade de Nijmegen (Holanda) apresentou 8 artigos entre os mais citados. O principal tema de interesse foi Cariologia (n = 40). "Cárie dentária" foi a palavra-chave mais frequente (n = 20). O número de citações na WoS-CC diminuiu 1,3% a cada ano (RP: 0,987, IC 95%: 0,975­1,000, p = 0,048).Conclusão: Este estudo bibliométrico permitiu analisar os ECs e RSs mais citados relacionadas à saúde bucal de crianças e adolescentes, destacando os autores, instituições e países mais prolíficos com base no número de citações.

Endodontic therapy in primary teeth: a bibliometric analysis of the 100 most-cited papers

Abstract: The purpose of this review was to identify and analyze the main characteristics of the 100 most-cited papers in the field of endodontic therapy in primary teeth. A search for the most-cited articles was conducted in the Clarivate Analytics Web of Science 'Core-Collection' (WoS-CC) database up to December 2020. Papers were ranked in descending order, by number of citations, and each paper was matched with the citation count on Scopus and Google Scholar. Two independent reviewers selected the most-cited papers and analyzed it according to the number and density of citations, year and journal of publication, authors, countries and contributing institutions, study design, topic of the paper, and keywords. Spearman's correlation and Poisson regression were used to determine associations between the number of citations and study characteristics. The citation count varied from 15 to 135 (WoS-CC), 8 to 141 (Scopus), and 14 to 317 (Google Scholar). Of the 306 contributing authors, most paper contributions were from Sakai VT, Oliveira TM, and Machado MAAM (5 each). Most of the papers originated from the USA (n=21) and Brazil (n=18). Randomized trials were the most common study design (n=32), and "pulpotomy" was the most frequently used keyword (n=35). Poisson regression showed that the number of citations decreased by 1.5% each year, and increased by 9.7% for each unit of impact factor. This bibliometric analysis highlighted papers, authors, and institutions that have contributed to endodontic therapy in primary teeth. Common terms of interest in this research area was also identified, representing the first bibliometric analysis on this subject.
