Abstract

Objectives: A massive number of articles are published every year concerning dentistry, and it is a superhuman task to read and get actualized about it. The aim of this study is to create a list of higher altmetric scores articles in dentistry and teach how to perform this kind of bibliometric analysis.
 
Material and Methods: Research on the term "dentistry" was done using the Dimensions app (retrospective study). Results were ranked in altmetric citations and analyzed through Microsoft Excel to create some tables and graphics to facilitate data visualization. Graphical illustration of keywords was created using VOSviewer. Some statistical tests were performed with a confidence interval at 95% (p<0.05).
 
Results: The United States is the country that leads this list of high interest in dentistry articles, and some fascinating subjects can be noted, like growing interest in dental office aggressions, preventive care, and phytotherapy, among others. A practical guide how to perform an altmetric analysis was discussed.
 
Conclusion: Altmetric analysis is a new web-based, valuable manner to scientific updates, a complementary analysis to bibliometric analysis. Altmetrics is a free, useful, quick and available to everyone way to update in dentistry.
 
Clinical Relevance: altmetrics is a new and efficient manner to be attualized.
 
Objectives statement: The reader should know this free type of bibliometric analysis and to know how to perform it.
 
Keywords: Social media; Altmetric; Citation; Impact Factor; Bibliometrics; Dentistry; Twitter

Introduction

Humankind has a solid basis for evolution through science. Researches and their publications are fundamental to science spread, and when scientists publish a magnificent article, this article could improve many concepts. A terrific science publication could lead to a series of other important scientific papers, resulting in the benefit of science and humanity.

Some tools were created to analyze these articles, and scientometrics is one of them. Scientometrics, metric values of scientific papers, can be divided into some other fields, like bibliometrics and altmetrics. Bibliometrics uses statistical methods to analyze books, articles, or any scientific paper through some tools like citation analysis, a more traditional way of assessing scientific impact. Altmetrics is an alternative form of scientometrics, using internet information to calculate the web impact of scientific papers and gaining space in science. A significant advantage of altmetric analysis is its availability, given that altmetrics is free.

This retrospective study provides a list of the most mentioned articles related to dentistry. The author hypothesizes that any kind of study or professional level could be aided with some form of bibliometric analysis, like altmetrics, and this could save time and effort in any level of study. The specific aim of this study was to produce this list of top 100 articles with highest altmetric score, with some statistical tests performed to confirm more exciting topics and to show steps to perform an altmetric search. This analysis could help dentists of all specialities to get informed concerning their own speciality.

Material and Methods

A bibliographic search was done through the Dimensions app on April 17, 2021, using the strategy “dentistry” in the "Title and Abstract" option from 1839 until 2021. Articles were ordered in altmetric citations (Altmetric LLP, London, UK), and data were tabled and analyzed through Microsoft Office Excel 2010 (Microsoft, Richmond, USA) using statistical tests and charts. Articles with no relation to dentistry were excluded manually as duplicates (systematic review updates).

Data were analyzed to output the most relevant and up-to-date scientific papers about dentistry according to the Altmetric Attention Score (AAS). AAS extracts data from some web-based sources like Twitter, Facebook, or Mendeley readers. For each different indicator, AAS uses a different weight [Table 1 and Figure 1].

Figure 1: Example of Altmetric score in Dimensions.

The top 100 articles are based on the Altmetric score. For each article included, we extracted: Altmetric Attention Scores, number of scientific citations (bibliometrics), journal title, country of origin, institution, subject categories. Country of origin and affiliate institution was linked to the corresponding author. In case of the absence of this information, data were used from the last author. If any data are not available, it was considered as Not Found (NF). Articles with no relation to dentistry and published by any non-health professionals were excluded. Any discordance of data was solved by the authors' consensus. Some tables and graphs were created in order to facilitate data visualization through Microsoft Office Excel and VOS viewer (Leiden University, Leiden, The Netherlands).

Results

We have found 112,778 articles about dentistry and, depending on the bibliographic platform, and this number can reach more results. A PubMed search, on the same date, has achieved 625,291 articles. The list of the top 100 dentistry articles with the highest AAS is provided in Table 2.

Table 2: List of the 100 articles order through AAS.

Mean AAS was [56,65], ranging from [54]100 to 1250 [1]. A total of 63 different journals are part of this list; Journal of the American Dental Association has the higher number of articles in this list, 14 followed by British Dental Journal and Journal of Dental Research with six. Mean number of citations is 21,50, ranging from 0 [37,41,46,55,87] to 2147 [22] citations.

There are 75 different worldwide institutions from 19 countries and four continents. University College of London leads the list with six published articles, followed by New York University, State University of New York, University of Michigan and University of Sydney with three articles. United States of America leads the list of countries of origin with a much larger quantity of articles than average amount, 40 articles followed by United Kingdom with 17 and Australia with 6 published articles [Figure 2].


Figure 2: Countries of origin of top 100 articles with highest AAS.

Richard Geddie Watt, Head of Department of Epidemiology and Public Health of University College London is the author with the most significant number of articles on this list. Two articles about oral health care [27,48] and one about opportunity for a reform in dentistry in this COVID-19 pandemic [63]. Two of these articles were published in a very high impact factor journal [27,63].

Articles, topics were divided into basic sciences/dental materials, cariology/oral health, endodontics, forensic dentistry, implantology, oral and maxillofacial surgery, pathology, patients with special needs, pediatrics, periodontology, perspectives and new technologies, pharmacology, restorative/prosthetic dentistry, and veterinary dentistry. More common keyword related to “dentistry” are “humans”, “female”, “male”, “adult” and “child”. An interesting fact about keyword on dentistry search is, next more cited keyword, on sixth place, is “covid-19”. A graphical representation of keywords [Figure 3] and authors [Figure 4] was performed through VOS viewer software.
