A bibliometric analysis of minimally invasive dentistry: A review of the literature from 1994 to 2021

STATEMENT OF PROBLEM

Minimally invasive dentistry is a technique for the maximal preservation of healthy tooth structures and has been a focus of attention in dental research. However, a detailed bibliometric analysis focusing on research related to minimally invasive dentistry is lacking.

PURPOSE

The purpose of this bibliometric analysis was to analyze leading countries and organizations and to identify the preferred journals, the most productive authors, and the most commonly used keywords in the field of minimally invasive dentistry.

MATERIAL AND METHODS

The search was performed by using the Scopus database, and publications pertinent to the field of minimally invasive dentistry from 1994 to 2021 were identified. A bibliometric analysis with reference to citations and documents, authors, journals, and keywords was performed. A total of 391 articles published in Scopus indexed journals between 1994 and January 2021 were analyzed by using a software program.

RESULTS

A continuing yet steady increase in research publications was identified, with a substantial increase in publications since 2013. The United States and Germany were the countries that published the most articles (98 and 46, respectively), articles that received 1877 and 806 citations, respectively. Cardiff University, UK, was the most productive organization that received 212 citations. The most highly cited articles were from the Q1 category. Blum from King's College London was the highest-cited author in this field.

CONCLUSIONS

Considerable advancement has been made in minimally invasive dentistry, as demonstrated by the increase in the number of publications linked with collaboration among various authors, nations, and institutes. This citation analysis gives a perspective on the progress of research in the field of minimally invasive dentistry and allows identification of the most significant and pertinent research areas.

Evaluation of the research trends on perfluorinated compounds using bibliometric analysis: knowledge gap and future perspectives

Detection of perfluorinated compounds (PFCs) in the environment has been a global concern because of the risk they pose due to their endocrine-disruptive properties. This study analyzed the global trends and research productivity of PFCs from 1990 to 2021. A total number of 3256 articles on PFCs were retrieved from the Web of Science focusing on different environmental and biological matrices. An increase in the productivity of research on PFCs was observed during the survey period which indicates that more research and publications on this class of contaminants are expected in the future. Evaluating the most productive countries and the number of citations per country on PFCs research shows that China and the United States of America were ranked in first and second places. It was also observed that research on PFCs received the most attention from scientists in developed countries, with little research emerging from Africa. Hence, research on PFCs in developing countries, especially low-income countries should be promoted. Consequently, more research programs should be implemented to investigate PFCs in countries and regions where research on these contaminants is low. The study will help researchers, government agencies and policymakers to tailor future research, allocation of funds to PFCs research and countries' collaboration.

Effects of Photobiomodulation on Oral Mucositis: Visualization and Analysis of Knowledge

This review article mapped and analyzed the most cited articles on the association of photobiomodulation (PBM) with oral mucositis (OM) and the evolution of clinical protocols in the area. A comprehensive search was performed on the Web of Science Core Collection (WoS-CC) database, leading to the extraction of information such as title, authors, abstract, journal name, number, average of citations, study design, year of publication, institutions, continents, countries, type of laser used, irradiated anatomical points, primary anti-cancer therapy, and laser parameters. Among those, clinical trials and literature reviews were the most common study designs. The main type of laser used was the InGaAlP diode, with a wavelength ranging from 630-660 nm, power going in 40-100 mW, and energy density ranging from 0.375-22 J/cm². As for the anatomical sites irradiated by PBM, the cheek mucosa, upper and lower lips, lateral tongue, and bottom of the mouth stood out. This analysis highlights an increasing interest in PBM as a supportive treatment in cases of OM, as well as the evolution of the technique, types of laser devices, and protocols used.

INTRODUCTION

This study aimed to identify and analyze the 100 most-cited articles published in orthodontic scientific journals in the past 21 years.

METHODS

The research was conducted in the Thomson Reuters Web of Science data citation index, considering articles from 2000 to 2020 and the category of dentistry, oral surgery, and medicine. Information about the number of citations, citations per year, title, authors, year of publication, the title of scientific journals, type of study, keywords, and thematic field were extracted for each article. Descriptive statistical analyses were performed to evaluate the collected data. The Pearson correlation analysis was used to explore the relationship between publication and the number of citations received. The VOSviewer software (Leiden University Center for Science and Technology Studies, Leiden, the Netherlands) was used to generate the keyword cooccurrence network.

RESULTS

The number of citations of the 100 selected articles ranged from 122 to 547. The journal with the largest number of cited articles was the American Journal of Orthodontics and Dentofacial Orthopedics. Most of the papers were cross-sectional and longitudinal studies, and the most frequent thematic fields among the selected articles were anchorage, root resorption, and rapid maxillary expansion. Orthodontic treatment, anchorage, and root resorption were the most frequent keywords.

CONCLUSIONS

Bibliometric analysis of citations revealed a greater centralization of orthodontic studies. Most of the articles were published in a single journal and by one country. Anchorage is a trending topic in orthodontics, and cross-sectional and longitudinal studies are the most-cited types of papers.

A bibliometric analysis of top 100 most-cited articles in dentistry with author(s) affiliated with Taiwan institutes

BACKGROUND

Citation analysis can provide a historical perspective in the advancement of research, evolution, and areas of research. Taiwan exhibits rigorous academic and scientific activities in dentistry; however, based on its empirical contribution in research, there is no report in the literature analyzing the top-cited articles published by authors affiliated with Taiwan institutes. The purpose of this study was to analyze the citation characteristics of the top 100 most-cited articles published in dentistry with author(s) affiliated with Taiwan institutes.

METHODS

The Scopus database was used to search the qualified articles with authors from Taiwan published in journals. The bibliometric parameters, including year of publication, study design, research fields, citation half-life, self-citation, institute of origin, and international collaboration were analyzed. Multivariable linear regression in generalized linear model was used to find associate factors related to trends of citation counts.

RESULTS

The top 100 most-cited articles were determined by analyzing 7667 articles from the Scopus database. The steadily increasing trends were observed in the number and percentage of articles of author(s) affiliated with Taiwan institutes to the world. The most common study design was the in vitro research (55 %). The majority citation half-life is 3-5 and 6-8 years, and self-citation counts were between one to five times (n = 26). The percentage of international collaboration of these most-cited articles was 32%, and the main collaboration country was the United States. By using multivariable linear regression in the generalized linear model, the associated factors, study design, and self-citation were significantly associated with the escalating trends of citation counts.

CONCLUSION

This is the first study that provides valuable information in the dentistry regarding the academic activity, and empirical contribution of author(s) affiliated with Taiwan institutes in the world. The trends of citation characteristics were significantly correlated with study design and self-citation of these articles.

The Top 100 Most-Cited Papers in Cariology: A Bibliometric Analysis

A highly cited paper is seen as a landmark in any field and can influence both research and clinical practice. This study aimed to quali-quantitatively analyze the 100 most-cited papers in Cariology. A search strategy was first determined using specific keywords related to the field. A comprehensive search was then conducted in the Thompson Reuters Web of Science citation indexing database up to April 2019. Papers focused on any aspect of Cariology were included. A panel of 4 researchers conducted the selection of papers and extracted data on the number of citations, title, authors, country, year, journals, study design, and topic of interest. Scopus and Google Scholar were also searched to compare the number of citations. The VOSviewer software was used to generate bibliometric networks. The number of citations among the top 100 most-cited papers ranged from 168 to 1,961 with a mean of 292,66. Three papers had more than 1,000 citations. The Journal of Dental Research (20%) and Caries Research (17%) had more top papers. The oldest and the most recent papers were published in 1960 and 2015. Literature reviews (35%) and laboratorial studies (31%) were the most common study designs. The countries with the highest number of most-cited papers were the USA (40%), Sweden (10%), and Japan (9%). The most studied fields of interest were etiology/pathogenesis (41%) and prevention (20%). VOSviewer maps revealed collaborative networks between countries and organizations. The top 100 most-cited papers in Cariology were published mainly by European and Anglo-Saxon American authors and were composed mainly of literature reviews with etiology/pathogenesis as the most frequent topic of interest.

The 100 most-cited papers in oral medicine and pathology

This study aimed to analyze the 100 most-cited papers in the field of oral medicine and pathology over time, identifying the areas of more intense research. Papers in journals of oral medicine and pathology were identified using the Web of Science database. The specified research period was between 1900 and 2019. Descriptive statistics was used to analyze the data. Pearson's correlation analysis was used to explore the relationships among Web of Science citations, Dimensions citations, and Altmetric Attention Score. The number of citations of an article in the top 100 most-cited papers published in 1953 or later ranged from 541 to 3623. The papers were published in 47 different journals. The New England Journal of Medicine, American Cancer Society, and Nature Genetics published the most papers. Authors from 18 different countries published papers on head and neck cancer, craniofacial congenital anomalies, and osteonecrosis. Most of the papers were laboratory and descriptive studies. A correlation analysis showed a strong correlation only between Web of Science and Dimensions citations. In sum, although non-specific journals for pathology and oral medicine published the majority of the 100 most-cited papers, this biometric citation study show that head and neck cancer was the issue with the most citations. Together, these results make an important scientific contribution by providing a historical perspective on the research carried out.

Systematic mapping of organophosphate contaminant (OPC) research trends between 1990 and 2018

Since the addition of polybrominated diphenyls and organochlorine pesticides (OCPs) to the world banned list, toxic organophosphate contaminants (OPCs) such as organophosphate flame retardants and organophosphate pesticides have been, respectively, used as substitutes. These chemicals are reported to be more toxic than their halogenated counterparts. It is rare to find a study that focuses on visualising the publication trends of these chemical classes. In this study, we employed a bibliometric model to systematically map research activities between 1990 and 2018 using OPC articles retrieved from the WoS and Scopus databases. A total of 1090 articles were retrieved from the hybrid databases with an article/author and author/article ratio of 0.33 and 3.02, respectively. Articles on OPC studies were positively correlated with the number of years (r² = 0.96; y = 0.23x² - 3.82x + 27.90) suggesting an increase in the number of articles on this subject in future. The USA ranked first in terms of articles (n = 245) and citations (n = 12,922) followed by China and India (203 and 89 articles, respectively). Articles from China and the USA had strong collaboration with other countries. Research priorities and top author keywords included pesticides (n = 112), organophosphate (n = 83) and acetylcholinesterase (n = 60) and were also well represented in keywords-plus. Developed countries had higher outputs compared to developing countries. It was observed that from our thematic literature classifications, human toxicity, ecotoxicological impacts, and environmental monitoring of OPCs were of greater importance to scholars, thus indicating the direction of future research. Futuristic studies need to foster partnership with policymakers, journalists, consultants, farmers, artisans and community workers on OPC research. This will not only enhance scientific communication and community engagement but will also increase the awareness of these pollutants to the general public.

Systemic Manifestations of the Periodontal Disease: A Bibliometric Review

This bibliometric review aimed to identify and analyze the top 100 most-cited publications on the systemic manifestations of periodontal disease (PD). A literature search was performed using the Web of Science (WoS) 'All Databases', without any restriction of language, publication year, or study design. Of 4418 articles, the top 100 were included based on their citation count. After downloading the full texts, their bibliometric information was extracted and analyzed. The citation counts for the top 100 articles ranged from 156 to 4191 (median 217). The most productive years were 2003 and 2005, with 20 articles on the list. Majority of the articles were published in the Journal of Periodontology (n = 25). The top 100 articles were generated primarily from the USA (n = 61). Most of the publications were clinical trials (n = 27) and focused on the cardiovascular manifestations of PD (n = 31). Most of the articles were within the evidence level V (n = 41). A total of 58 studies received funding and the most frequently used keyword in the top articles was "periodontal disease" (n = 39). The current citation analysis presents insights into the current trends in the systemic manifestations of periodontal disease.

Top 100 most-cited papers in core dental public health journals: bibliometric analysis

OBJECTIVE

This quali-quantitative study analysed the 100 most-cited papers in core dental public health (DPH) journals focusing on understanding international knowledge production.

METHODS

The DPH journals were selected from titles and scopes at Web of Science Core Collection database up to March 2020. Further comparisons were performed at Scopus and Google Scholar databases. Some bibliometric parameters were extracted as follows: title, number of citations, citation density (number of citations per year), first author's country, year of publication, study design and subject. VOSviewer software was used to create graphical bibliometric maps.

RESULTS

Papers were ranked by the total number of citations, which ranged from 104 to 1,019, and six papers were cited more than 400 times. Papers were published from 1974 to 2013, mainly in Community Dentistry and Oral Epidemiology. Most frequent study designs were cross-sectional (30%) and nonsystematic review (25%). Most papers were from Europe (54%) and North America (31%). First authors were predominantly from the United Kingdom (17%), United States of America (17%) and Canada (14%). VOSviewer map of co-authorship demonstrated the existence of clusters in the research collaboration. Although epidemiology was the most frequent subject (84%), health services research presented eight times higher citation density.

CONCLUSIONS

Top 100 most-cited papers in core DPH journals were predominantly observational studies from Anglo-Saxon countries. Top 100 most-cited papers in core DPH journals tend to be cross-sectional studies carried out in the United States with highest citation in health services research. Locker D, Petersen PE and Sheiham A are a landmark for DPH field.

The level of evidence, scientific impact and social impact of clinical studies in periodontology: A methodological study

AIMS

To analyse the level of evidence (LOE) of clinical studies in the field of periodontology, and to investigate whether LOE is a predictor of scientific impact and social impact.

MATERIALS AND METHODS

Clinical studies published in five leading periodontal journals during 2015-2019 were identified. The LOE of included studies were assessed with a modified LOE classification system based on Oxford 2009 LOE, Oxford 2011 LOE and GRADE guidelines. Citation counts were harvested from Web of Science and Scopus. Altmetric Attention Scores (AAS) were obtained from Altmetric Explorer. Multivariable generalized estimation equation (GEE) analyses were used to investigate association between LOE and citation count, as well as between LOE and AAS.

RESULTS

Among 768 studies included, the proportion of level-1, level-2, level-3 and level-4 was 10.4%, 44.8%, 13.7% and 31.1%, respectively. In the multivariable GEE analyses, high LOE was a significant predictor of higher average citation count (p = .010) and higher AAS (p < .001).

CONCLUSION

The LOE of clinical studies in the periodontal field is relatively high in general, although it varies significantly in different journals. Studies with high LOE tend to have greater scientific impact and social impact than low LOE studies.

The online attention to research in periodontology: An Altmetric study on the most discussed articles on the web

AIM

To assess the online attention to research in the field of Periodontology. To assess the correlation between the Altmetric Attention Score (AAS) and the citations count in Web of Science (WOS), Scopus and Dimensions.

MATERIAL AND METHODS

The articles were identified by a search performed through the Dimensions Free App. The search included the six journals related to periodontology listed in the Journal Citation Report (JCR) in the year 2017. The 200 articles with the highest AAS were collected and screened for data related to publication, authorship and research. Citations were harvested from WOS, Scopus and Dimensions.

RESULTS

The Journal of Clinical Periodontology was the most prevalent publication accounting for the 51, 5% of the published items followed by the Journal of Periodontology that published the 34, 5% of the 200 articles with the highest AAS. 65% of these articles were published between 2013 and 2018. The mean AAS was 33, 81 being Tweets and news outlets the most frequent Altmetric resources. Systematic reviews were the most prevalent study design. The correlation between the AAS and the citations in WOS, Dimensions and Scopus was poor. A strong correlation exists between the citations in WOS, Dimensions and Scopus.

CONCLUSIONS

Online attention to periodontal research is high. Systemic interaction studies had a significantly higher visibility. The classic citations count in combination with the AAS can offer a more comprehensive insight into research by highlighting what is valuable for the researcher and for the lay persons. The online profile of journals should be edited to facilitate spread of research information in non-scholar audiences.

BACKGROUND

The most-cited papers help to better understand important characteristics of this specific science field.

OBJECTIVE

To analyse the 100 most-cited papers in the field of Paediatric Dentistry.

DESIGN

A search of the most-cited papers in Paediatric Dentistry journals was performed using journals included in the category of 'Dentistry, Oral Surgery & Medicine' in the Thompson Reuters Web of Science citation indexing database up to December 2018. Two researchers performed the data extraction, which included: number of citations, title, authors, country, year, journals, study design, and thematic area.

RESULTS

The number of citations of each paper included in the top 100 most-cited ranged from 42 to 182 (mean: 64.51). Seven papers were cited more than 100 times. Most of the papers were published in the International Journal of Paediatric Dentistry (36%), between 2006 and 2015 (55%), with a cross-sectional design (39%). Twenty-six authors participated in two or more papers. The countries with the highest number of most-cited papers were the United States (25%), Australia (11%), and Brazil (9%). Cariology was the most studied thematic area.

CONCLUSION

The evaluation of the top 100 most-cited papers in Paediatric Dentistry journals allowed for a better understanding of the world scenario regarding this research field.

A bibliometric analysis of the 103 top-cited articles in endodontics

Objective: The purpose of this study was to identify the 100 top-cited articles in endodontics and analyse their bibliometric characteristics. Material and methods: The Web of Science database was reviewed to identify the relevant articles. Results: One hundred and three articles were included because the last four articles had the same number of citations. The top-cited article received 2115 citations. The articles were published in 28 different journals, with the most popular publication being the Journal of Endodontics (n = 36). The most prolific country was the United States (n = 41), followed by Sweden (n = 17) and Switzerland (n = 8). The most prolific author and institution were M. Torabinejad (n = 12) and Umeå University (n = 9), respectively. The majority of articles were of a basic science nature (n = 55), while endodontic microbiology (n = 24) was the most frequent subspecialty. The most common study design used in clinical articles was non-randomized experimental study (n = 5). Half of the clinical articles (n = 11) had a level III evidence score. Conclusions: The present citation analysis provides insights into the historical progress and current trends in endodontics.

Brazilian Articles in Top-Tier Dental Journals and Influence of International Collaboration on Citation Rates

Abstract This study investigated the presence of co-authorship from Brazil in articles published in top-tier dental journals and analyzed the influence of international collaboration, article type (original research or review), and funding on citation rates. Articles published between 2015 and 2017 in 38 selected journals from 14 dental subareas were screened in Scopus. Bibliographic information, citation counts, and funding details were recorded for all articles (N=15619). Collaboration with other top-10 publishing countries in dentistry was registered. Annual citations averages (ACA) were calculated. A linear regression model assessed differences in ACA between subareas. Multilevel linear regression models evaluated the influence of article type, funding, and presence of international collaboration in ACA. Brazil was a frequent co-author of articles published in the period (top 3: USA=25.5%; Brazil=13.8%; Germany=9.2%) and the country with most publications in two subareas. The subjects with the biggest share of Brazil are Operative Dentistry/Cariology, Dental Materials, and Endodontics. Brazil was second in total citations, but fifth in citation averages per article. From the total of 2155 articles co-authored by Brazil, 74.8% had no co-authorship from other top-10 publishing countries. USA (17.8%), Italy (4.2%), and UK (3.2%) were the main co-author countries, but the main collaboration country varied between subjects. Implantology and Dental Materials were the subjects with most international co-authorship. Review articles and articles with international collaboration were associated with increased citation rates, whereas the presence of study funding did not influence the citations.

Bibliometric Analysis of Medication-Related Osteonecrosis of the Jaw: High Citation Rates but Low Evidence

PURPOSE

Citation analysis is one of the most commonly used bibliometric tools for measuring the academic importance of a report in a specific area of knowledge. The objective of the present study was to identify the 100 most cited reports on medication-related osteonecrosis of the jaw (MRONJ), determine their main bibliometric characteristics, and identify the bibliometric variables that affected the citation rates.

MATERIALS AND METHODS

We performed a data search in the Scopus database to determine the number of MRONJ article citations up to September 30, 2018. We next selected the 100 most referenced studies and recorded the following information: ranking according to the number of citations; citation density; number and names of authors; language and year of publication; country and institution of origin; financial support; journal name, impact factor, category, and quartile; type of research; evidence level; and area of study.

RESULTS

The 100 most cited reports had a mean citation density of 21.7 ± 20.7 (range, 6.2 to 99.4) and an h-index of 96. The 100 most cited reports on MRONJ had been published in 42 scientific journals, classified into 10 separate categories of the Journal Citation Reports; 56% of the articles were in the first quartile of their category. Most of the studies had been classified with a level of evidence of 4 (n = 45) or 5 (n = 29). In the bivariate analyses, only the conflict of interest (P = .002) was associated with citation density. After adjusting for numerous variables, conflict of interest (r = 0.27; P = .020) and country of the first author (r = 0.23; P = .043) were significantly associated with citation density.

CONCLUSIONS

The 100 most cited studies of MRONJ had a large number of citations and had been reported in journals with a high impact factor; however, the studies had a generally low evidence level and randomized clinical trials were lacking.

A survey of prevalence of narrative and systematic reviews in five major medical journals

Background

Systematic reviews may provide less biased evidence than narrative reviews because they observe a strict methodology, similarly to primary studies. Hence, for clinical research questions, systematic reviews should be the study design of choice. It would be important to evaluate the prevalence and characteristics of narrative and systematic reviews published in prominent medical journals. Researchers and clinicians give great value to articles published in such scientific journals. This study sought to evaluate the prevalence and characteristics of narrative and systematic reviews in the five highest-ranked general medical journals and investigate the associations among type of review, number of citations, and impact factor (IF).

Methods

We surveyed the five highest-ranked medical journals (The New England Journal of Medicine, The Lancet, The Journal of the American Medical Association, The BMJ, and Annals of Internal Medicine) for narrative and systematic reviews published between June 2015 and June 2016. We independently selected and extracted the data from the reviews by strictly following the pre-determined eligibility criteria (Systematic and narrative reviews that focused on the management of diseases). We conducted regression analyses to investigate the associations among review type, number of citations, and IF. We also descriptively reported narrative reviews containing some methodology that might be reproducible.

Results

Two hundred seventy-five reviews were included: 75 (27%) systematic; 126 (46%) narrative with some methodology reported, and 74 (27%) narrative reviews. In comparison to systematic reviews, narrative reviews were more frequently published in journals with higher IF (risk ratio [RR] = 1.114 (95% CI 1.080 to 1.149). Systematic reviews received more citations than narrative reviews (group formed by narrative and narrative with some methodology reported (RR = 0.985 95% CI 0.978 to 0.991).

Conclusions

Non-systematic evidence is the most prevalent type of evidence in reviews published in the five highest-ranked general medical journals. Narrative reviews were more frequently published in journals with higher IF. We recommend that journals limit their space for narrative information, and to address clinical research questions, these journals consider publishing systematic evidence exclusively.
