Longitudinal bibliometric investigation of published orthodontic research 2013-23: are we investigating patient-reported outcomes?

BACKGROUND: The published literature represents the fundamental basis of any academic specialty, including orthodontics. Orthodontic research outputs provide useful insight into clinical and research priorities, which can help inform future research efforts and resource outputs. In recent years, the need for more patient-reported outcomes in orthodontic research has been highlighted. OBJECTIVES: To identify the most common reported research subjects in orthodontics between 2013-23; (2) identify the main outcomes and types of study design associated with this research, including study design related to patient-reported outcomes; and (3) identify trends in this research activity based upon these findings. MATERIAL AND METHODS: A literature search was performed in a single electronic database (Scopus) to return all indexed publications with relevance to orthodontics published from 2013 to 2023. The 50 most-cited publications per year were then identified. Publication characteristics were extracted using a data collection sheet. Descriptive statistics including frequency distributions were calculated. RESULTS: A total of 14 397 publications were identified. Publications on orthodontic bonding made up 7.02% of all output, followed by materials (5.88%) and tooth movement (5.42%). Subsequent analysis of the most-cited publications per year revealed the most frequently published subjects were aligners (12.5%), orthodontic tooth movement (9.45%), and digital workflow (9.09%), and the most common study designs were in vitro (19.09%) and retrospective observational studies (15.45%). The most common outcome type was morphological features of malocclusion (26.9%). Conversely, patient-focused measures were only reported in 12.7% of studies. CONCLUSIONS: Orthodontic research outputs are dynamic but do show consistent research interest in certain subjects. There is a predilection for the reporting of clinician-focused outcomes; whilst these have some value, more efforts should be focused on conducting rigorous and robust studies that include patient-reported outcomes.

Top 100 most-cited papers on diabetes mellitus in Dentistry: a bibliometric study.

This study assessed the features of the 100 most-cited papers on diabetes mellitus (DM) in dentistry using bibliometric measures. A search of the most cited papers on DM using journals included in the category "Dentistry, Oral Surgery and Medicine" in the Web of Science database up to January 2023 was performed. The complete bibliographic records of the selected papers were exported in plain text or Research Information Systems (RIS) file format. The following bibliometric indicators were collected: title, year, authors, number of citations, mean number of citations, institution, country, continent, study design, journal, impact factor, and keywords. Graphical bibliometric networks were created using the VOSviewer software. The number of citations for the 100 most-cited papers in DM research ranged from 111 to 566. Six papers each had more than 400 citations. Most were observational studies (n = 50) from the United States (USA) (n = 23) and were published in the Journal of Periodontology (30%; n=30). Robert Genco was the most cited author and contributed the most to the top 100 articles (3,653 citations; n = 13). The VOSviewer map of co-authorship showed the existence of clusters in research collaboration. The most prolific institutions were the Universities of Buffalo and Michigan (n = 6 each). "Diabetes mellitus" was the most frequent keyword, with 31 occurrences. In conclusion, the most cited studies that investigated the relationship between dentistry and DM were in periodontology. Observational studies, primarily from the USA, have been the most cited thus far.

Spin in dental publications: a scoping review.

The aim of this review was to map the practice of spin in scientific publications in the dental field. After registering the review protocol (osf.io/kw5qv/), a search was conducted in MEDLINE via PubMed, CENTRAL, Embase, Scopus, LILACS, ClinicalTrials.gov, and OpenGrey databases in June 2023. Any study that evaluated the presence of spin in dentistry was eligible. Data were independently extracted in duplicate by two reviewers. After removing duplicates, 4888 records were screened and 38 were selected for full-text review. Thirteen studies met the eligibility criteria, all of which detected the presence of spin in the primary studies, with the prevalence of spin ranging from 30% to 86%. The most common types of spin assessed in systematic reviews were failure to mention adverse effects of interventions and to report the number of studies/patients contributing to the meta-analysis of main outcomes. In randomized controlled trials, there was a focus on statistically significant within-group and between-group comparisons for primary or secondary outcomes (in abstract results) and claiming equivalence/noninferiority/similarity for statistically nonsignificant results (in abstract conclusions). The practice of spin is widespread in dental scientific literature among different specialties, journals, and countries. Its impact, however, remains poorly investigated.

Noncarious cervical lesions: A bibliometric analysis and future research trends.

OBJECTIVE: The present bibliometric review analyzed the literature on non-carious cervical lesions (NCCLs) to explore the current state and propose future research topics. DATA: An electronic search was performed, only full scientific papers published in English were included. SOURCES: A search was conducted of all databases in the Web of Science (WOS) platform for available publications on the topic of NCCLs. STUDY SELECTION: 959 publications were retrieved, and the following data were extracted and analyzed: number of publications, study topics, keywords, study type, authors, affiliations, countries, funding agencies, journals and citations. Articles on NCCLs have been increasing in count, ever since they were first mentioned in the literature. Therapy alternatives account for 628 with few on prevention, and the majority were clinical. Brazil has published the most on NCCLs as well as has the highest number of authors and the most funded articles. The three journals that published the most on the topic were Operative Dentistry, Journal of Dentistry and Clinical Oral Investigations. CONCLUSION: The findings of this study provide a full picture of the current literature on NCCLs, research trends, knowledge gaps, and areas requiring further investigation. CLINICAL SIGNIFICANCE: By highlighting evolving treatment strategies and potential gaps in prevention, researchers can contribute to the advancement of clinical practice. This can improve patient care and outcomes in the management of NCCLs, while also providing valuable insights for policymakers to prioritize research funding and policy initiatives.

Evaluating global research trends in special needs dentistry: A systematic bibliometrix analysis.

OBJECTIVES: Special needs dentistry (SND) is a vast and fragmented field of study. This comprehensive bibliometric analysis aimed to evaluate the scope of SND, including the existing knowledge base, distribution structure, quantitative relationships, and research trends. MATERIAL AND METHODS: A systematic search was conducted on March 10, 2022, using the Web of Science Core Collection database, covering the period from 1985 to 2021, focusing on studies reporting on special needs populations in a dentally relevant context. Records were title-screened and analyzed for key bibliometric indicators. RESULTS: Among 48,374 articles, 13,869 underwent bibliometric analysis. Peak SND research occurred during 1985-1997. United States led in productivity, trailed by Brazil and Japan. University of Sao Paulo excelled in Brazil, University of Washington and University of North Carolina in the United States. The Journal of Dental Research was the most productive source of research and also had the highest number of citations, followed by Community Dentistry and Oral Epidemiology. Keyword analysis revealed that "elderly", "caries", and "epidemiology" were the most commonly used author keywords. CONCLUSIONS: This study represents the first bibliometric analysis of SND literature. It emphasizes the need for increased collaboration between institutions and authors. Furthermore, it suggests focusing on research input from non-dental disciplines and populations with rarer intellectual or developmental conditions.

Dental research related to COVID-19 in Brazil: research presented at the 38th SBPqO Meeting.

The aim of this study was to identify and describe the characteristics of coronavirus (COVID-19)-disease related dental research in Brazil presented at the 38th Annual Meeting of the Brazilian Division of the International Association for Dental Research (SBPqO). A search was carried out in the proceedings of the meeting to retrieve all abstracts. Those containing the term "COVID-19" in titles, abstracts, or keywords, and/or those of which the scope approached a COVID-19-related topic were included. The variables extracted from abstracts were: presenter category, field of study, design, data collection method, population, affiliation, and authors' gender. Descriptive and inferential statistics were used, with a significance level of α = 0.05. The search retrieved 185 abstracts, 5 did not meet study eligibility criteria and were excluded. COVID-19-related research was presented by either aspiring/associate members (67.8%) or beginner members (32.2%). Data collection methods were predominantly digitally mediated (65%), followed by secondary data use (25%), and in-person data collection (7.2%). Irrespective of the role of authorship, there were a ratio of two female authors to each male. Among the last authors, the ratio was three females to each male. Female lead authors more frequently came from the Southeast region (71.8%; p = 0.470). There was an association between presenter category and study design (p = 0.012), clinical and epidemiological studies were more concentrated among experienced presenters. In conclusion, female dental researchers affiliated to southeastern institutions approached the topic of pandemic more frequently than male colleagues. The use of digital technology for data collection may have long-lasting impacts on the teaching and publication of dental research.

Research interest on dental sealant in dentistry based on the 100 most cited articles: bibliometric analysis.

The aim of this study was to identify and analyze the characteristics of the 100 most cited articles about dental sealants (DS) in dentistry. In September 2023, a search was performed in the Web of Science Core Collection (WoS-CC) database. The following information was extracted from each article: number and density of citations, year of publication, authorship, journal, impact factor, keywords, study design, theme, continent, country, and institution. The citations of the WoS-CC were compared with those of the Scopus and Google Scholar databases. The VOSviewer software was used to generate collaborative networks. The number of citations ranged from 33 to 205. The articles were published between 1961 and 2016. Buonocore MG (7%) was the most prominent author among the most cited. The Journal of the American Dental Association was the most frequent journal (25%) and Journal of Dental Research (7.6) had the highest impact factor. Most studies had interventional (41%) and laboratory (31%) designs, mainly addressing DS effectiveness in the prevention and control of dental caries (86%). There was a predominance of publications from North America (46%) and the USA was the country with the highest number of articles (44%). The most frequent institutions were the Centers for Disease Control and Prevention (USA) and the University of Rochester (USA) (6% each). "Retention" was the most frequent keyword. In conclusion, the 100 most cited articles were mostly interventional and laboratory studies, addressing the retention and efficacy of DS. Most of the articles were concentrated in North America and Europe, demonstrating a little collaboration from other continents.

Five decades of research on immediate implant therapy: A modern bibliometric network analysis via Altmetric and level of evidence mapping.

AIM: To conduct a bibliometric network analysis to explore the research landscape of immediate implant placement (IIP) and provide insights into its trends and contributors. MATERIALS AND METHODS: The Scopus database was utilized as the bibliographic source, and a search strategy was implemented to identify relevant research articles. Various bibliometric parameters were extracted, including publication year, journal, authors, citations, and funding. The analysis involved examining authorship patterns, international collaborations, level of evidence, Altmetric data, and funding analysis. RESULTS: We identified a steady annual growth rate of 6.49% in IIP research. The top three countries contributing to research output were the USA, Italy, and China. Prolific authors were identified based on publication and citation metrics. International collaborations among different countries were observed. The level of evidence analysis revealed that over 30% of the articles fell into higher levels of evidence (levels 1 and 2). Altmetric data analysis indicated no significant correlations between citation counts and Altmetric Attention Score (AAS), and conversely a significant association with Mendeley readers count. Funding and open access did not significantly impact the bibliometric indices of the papers. CONCLUSIONS: The focus of research on IIP has been evolving as indicated by an exponential growth rate in this study. Only approximately 16% of the articles fit into level 1 evidence, therefore, emphasizing on higher quality level research study shortage in this field. Modern indices can be used as new bibliometric indicators as they also cover social media and online attention scores.

Reporting characteristics of systematic review abstracts published in the proceedings of the SBPqO meeting

Aim: This study aimed to assess the reporting characteristics of systematic review abstracts published in the proceedings of the Sociedade Brasileira de Pesquisa Odontológica (SBPqO) meeting. Methods: We selected abstracts published in the SBPqO meeting proceedings of 2019 and 2020, mentioning that a systematic review was conducted in the title, objective or methods sections. One researcher performed the screening and the data extraction after a pilot test training. The following data were extracted: affiliation of the primary author, dental specialization, the term "systematic review" mentioned in the title, reporting of the objective, reporting of eligibility criteria, reporting of information sources, reporting of the number of included studies and if a meta-analysis was performed. A descriptive analysis of the data was performed with data summarized as frequencies. Results: We included 235 abstracts. A total of 20 studies were from the Universidade de Uberlândia (8.5%), and the main specialization was Restorative and Esthetic Dentistry, with 47 studies (20%). Most of the studies mentioned the term "systematic review" in the title (n=219; 93.2%) and reported the objective (n=231; 98.3%). A great majority of studies did not report the eligibility criteria (n=97; 41.3%) or it was classified as unclear (n=96; 40.8%). The great majority of studies only reported the databases searched (n=103; 43.8%) or databases and date of search (n=74; 31.5%). Most of the studies reported the number of included studies (n=204; 86.8%). Conclusion: Based on this study, the reporting characteristics of systematic review abstracts published in the proceedings of the SBPqO meeting are satisfactory. However, there is room for improvement

How sample size influences research outcomes

Sample size calculation is part of the early stages of conducting an epidemiological, clinical or lab study. In preparing a scientific paper, there are ethical and methodological indications for its use. Two investigations conducted with the same methodology and achieving equivalent results, but different only in terms of sample size, may point the researcher in different directions when it comes to making clinical decisions. Therefore, ideally, samples should not be small and, contrary to what one might think, should not be excessive. The aim of this paper is to discuss in clinical language the main implications of the sample size when interpreting a study.

O cálculo amostral faz parte dos estágios iniciais de realização de um estudo epidemiológico, clínico ou laboratorial. Há indicações éticas e metodológicas para o seu emprego na elaboração de um trabalho científico. Duas pesquisas, realizadas com a mesma metodologia obtendo resultados equivalentes, e que diferem apenas no tamanho da amostra, podem apontar para diferentes direções no processo de tomada de decisão clínica. Portanto, as amostras estudadas idealmente não devem ser pequenas e, ao contrário do que pode-se pensar, não devem ser excessivas. O objetivo desse artigo é discutir, numa linguagem clínica, as principais implicações do tamanho das amostras na interpretação de um estudo.

Research training in dental undergraduate curriculum in Chile / Formación en investigación en las mallas curriculares de odontología en Chile

Research plays a central role in professional training in dentistry. There is a clear recommendation to include a minimum training in biomedical research at undergraduate level. In Chile, there is no standardized curriculum structure including research training for undergraduate students. Objective: To describe the presence of research courses in the undergraduate dental curriculum in Chile during 2014. Methodology: A descriptive cross-sectional study. The curriculum for all Chilean universities teaching dental careers and updated during 2014 were analyzed. Results: The dental curriculum for twenty Chilean universities was analyzed. On average, each university has 4.05+/-2.06 research courses (semesterly) from which 1+/-0.92 are thesis courses. In the private universities, these numbers were 4.64+/-1.91 and 1.18+/-0.87 respectively. Meanwhile, these numbers were 3.33+/-2.12 and 0.78+/-0.97 respectively in the traditional universities. Sixty percent of universities have thesis or research project courses. Conclusion: There is a disparate presence of research courses in the undergraduate dental curriculum in Chile, with a higher presence in private institutions. However, this does not actualize a greater scientific production by them.

La investigación juega un rol central en la formación del profesional en Odontología. Existe una clara recomendación de incluir en el pregrado una cantidad mínima de formación en investigación biomédica. En Chile no existe una estructura curricular estandarizada que incluya investigación a alumnos de pregrado. Objetivo: Identificar la presencia de asignaturas de investigación en las mallas curriculares de las carreras de odontología dictadas en Chile para el año 2014. Metodología: Estudio descriptivo de corte transversal, la unidad de análisis correspondió a las mallas curriculares de la carrera odontología, de todas las universidades dictantes en Chile y actualizadas al año 2014. Resultados: Se analizaron las mallas curriculares de las carreras de odontología de 20 universidades chilenas. En promedio cada universidad tiene 4,05+/-2,06 ramos (semestrales) de investigación y de los cuales 1+/-0,92 son ramos de tesis. En las universidades privadas estas cifras son 4,64+/-1,91 y 1,18+/-0,87 respectivamente, mientras que en las tradicionales fueron de 3,33+/-2,12 y 0,78+/-0,97 respectivamente. El 60 por ciento de las universidades tiene algún ramo de tesis o proyecto de investigación. Conclusión: Existe una dispar presencia de ramos de investigación en los programas curriculares de odontología en Chile, con una mayor presencia en instituciones privadas. Sin embargo, esto no se materializa en una mayor producción científica por parte de ellas.

Bibliometric analysis of scientific articles published in Brazilian and international orthodontic journals over a 10-year period

Objective: This study aimed at describing the profiles of Brazilian and international studies published in orthodontic journals. Methods: The sample comprised 635 articles selected from two scientific journals, i.e., Dental Press Journal of Orthodontics and American Journal of Orthodontics and Dentofacial Orthopedics, which were analyzed at three different intervals over a 10-year period (1999 - 2004 - 2009). Articles were described in terms of knowledge domain, study design, and country of origin (or state of origin for Brazilian papers). Results: The most frequent study designs adopted in international studies were cohort (23.9%) and cross-sectional (21.7%) designs. Among Brazilian papers, cross-sectional studies (28.9%) and literature reviews (24.6%) showed greater frequency. The topics most often investigated were dental materials (17%) and treatment devices (12.4%) in international articles, with the latter topic being addressed by 16% of the Brazilian publications, followed by malocclusion, with 12.6%. In all cases, the most frequent countries of origin coincided with the countries of origin of each journal. Conclusions: The majority of the studies analyzed featured a low level of scientific evidence. Moreover, the findings showed that journals tend to publish studies produced in their own country of origin, and that there are marked discrepancies in the number of papers published by different Brazilian states. .

Objetivo: determinar o perfil das publicações nacionais e internacionais nos periódicos de Ortodontia. Métodos: foram avaliados 635 artigos da Revista Dental Press de Ortodontia e Ortopedia Facial e American Journal of Orthodontics and Dentofacial Orthopedics, em três tempos distintos, dentro de um intervalo de 10 anos (1999, 2004 e 2009), caracterizando as áreas de conhecimento, os delineamentos utilizados e identificando países e estados brasileiros com maior produção científica. Resultados: os delineamentos dos estudos internacionais mais utilizados foram estudos de coorte (23,9%) e transversal (21,7%). Em estudos nacionais, destacam-se os delineamentos transversais (28,9%) e revisão de literatura (24,6%). Nas publicações internacionais, as categorias temáticas mais pesquisadas foram materiais dentários (17%), além de dispositivos de tratamento (12,4%); essa mesma categoria esteve presente em 16% das publicações nacionais, e a má oclusão dentária em 12,6%. A nacionalidade das publicações mais observada foi a do próprio país de origem do periódico. Conclusões : a maioria dos artigos publicados refere-se a estudos de menor potencial para estabelecer evidências científicas. Além disso, a situação detectada ilustra a propensão das revistas publicarem os artigos produzidos dentro de seu país de origem, bem como as disparidades entre os estados do Brasil quanto ao número de publicações. .

Queilite actínica- perfil da produção científica em odontologia do Brasil nos últimos dez anos / Queilitis actínica- perfil de la producción científica en odontología de Brasil en los últimos diez años / Actinic cheilitis profile of the scientific production in dentistry of Brazil in the last ten years

A queilite actínica é uma lesão cancerizável por conseqüência da exposição prolongada e contínua ao sol, afetando preferencialmente o lábio inferior. Objetivo: traçar o perfil da pesquisa odontológica desenvolvida no Brasil durante os últimos 10 anos, no que diz respeito à queilite actínica. Métodos: realizou-se um estudo transversal, por meio da observação indireta dos resumos dos trabalhos apresentados nas reuniões da Sociedade Brasileira de Pesquisa em Odontologia- SBPqO, no período de 2001 a 2011, resultando 42 resumos, os quais continham as palavras queilite actínica, ceratose actínica do lábio, queilose actínica e/ou actinic cheilitis. Os dados foram organizados e analisados com o software Epi Info versão 3.5.1 e apresentados por meio da estatística descritiva e analítica. Nas análises bivariadas, utilizou-se o teste do Qui-quadrado (p < 0,05). Resultados: obteve-se um pico de trabalhos apresentados no ano de 2006 e 2008; concentração da produção científica na região sul e sudeste, porém, com singela contribuição do estado da Bahia; predomínio de estudos de natureza observacional com corte transversal. Observou-se que 35,7 porcento receberam apoio de órgãos governamentais, sendo o CNPq responsável pela maioria do financiamento (16,7 porcento). Não foi verificada diferença significativa quanto à distribuição do fomento entre as instituições públicas e particulares (p = 0,103), assim como entre as federais e estaduais (p= 0,225). Conclusão: embora escassos, alguns estudos demonstram a importância de pesquisas que esclareçam os mecanismos moleculares que influenciam no comportamento biológico da queilite actínica. Assim, pode desenvolver uma terapêutica segura e eficaz que não permita o avanço da doença a quadros mais graves. Para isso é necessário uma maior participação das universidades e agências financiadoras para possibilitar a execução de pesquisas com maior potencial de evidência científica(AU)

Los datos fueron organizados y analizados mediante Epi Info versión 3.5.1 y se presentó la estadística descriptiva y analítica. En variados análisis, se utilizó la prueba de qui-cuadrado (p < 0,05). Resultados: se observó un pico de los trabajos presentados en 2006 y 2008, la concentración de la producción científica en el sur y sureste, pero con un sencillo aporte de Bahía; predominio de estudios de carácter observacional. Se observó que el 35,7 por ciento recibió el apoyo de los organismos gubernamentales, CNPq fue responsable de la mayoría de los fondos (16,7 por ciento). No se encontraron diferencias significativas en cuanto a la distribución del desarrollo entre las instituciones públicas y privadas (p= 0,103), y entre las autoridades federales y estatales (p= 0,225). Conclusión: Sin mucha frecuencia algunos estudios muestran la importancia que tiene la investigación para aclarar los mecanismos moleculares que influyen en el comportamiento biológico de la queilitis actínica. Por lo tanto, se puede desarrollar un tratamiento seguro y eficaz que no permita la progresión de la enfermedad. Esto requiere una mayor participación de las universidades y organismos de financiación que permitan la aplicación de la investigación con el mayor potencial de la evidencia científica(AU)

The actinic cheilitis is a carcinogenic injury resulting from extended and continuous exposure to the sun, mainly affecting the lower lip. Objective: To describe the profile of dental research about actinic chelitis conducted in Brazil in the last 10 years. Methods: A cross-sectional study through indirect observation of the paper abstracts, which had been submitted in the Brazilian Society for Dental Research-SBPqO meetings held from 2001 to 2011. It was observed that 42 abstracts contained the words actinic cheilitis and actinic keratosis of the lip. The data were organized and analyzed using Epi Info version 3.5.1 and presented using descriptive and analytical statistics. In the bivariate analyzes, the chi-square test (p < 0.05) was used. Results: A peak of papers was presented in 2006 and 2008; the scientific production was concentrated in the south and the southeast areas, with simple contribution by the state of Bahia and predominance of the observational studies. It was observed that 35.7 percent received support from the governmental agencies, and the CNPq contributed most of the funding (16.7 percent). There were no significant differences in the distribution of dental research works between the public and the private institutions (p= 0.103), as well as between the federal and the state authorities (p= 0.225). Conclusions: Although uncommon, some studies showed the importance of research to clarify the molecular mechanisms that influence the biological behavior of actinic cheilitis. Hence, a safe and effective treatment may be provided to prevent the advance of disease. This requires greater involvement of universities and of funding agencies to allow applying the results of research with the greatest potential for scientific evidence(AU)
