Since its inception in 1919, the Journal of Dental Research has continually published highquality articles that span the breadth of research topic relevant to dentistry, oral surgery andmedicine. As part of the journal’s centennial celebrations, we have conducted an electronicsearch on Scopus to identify and analyse the top 100 most-cited papers from 1919 to 2018.Since the Scopus does not capture older citations, we conducted an additional analysis byGoogle Scholar to identify key papers published in the first 50 years of the journal. Based onthe Scopus, the articles were ranked in descending order based on their citation counts. Thecitation counts of the 100 selected most-cited articles varied from 262 to 1503. The year inwhich the largest number of top 100 articles were published was 2004 (n=6). Among 334authors, the greatest contribution was made by D.H. Pashley (n=9). Within the top 100, themajority of articles originated from the United States (n=52). ‘Research Reports – Biomaterials& Bioengineering’ was the most frequent category of cited articles (n=35). There was nosignificant association between total citation count and time since publication (correlationcoefficient = -0.051, p = 0.656). However, there was a significant negative association ofcitation density (correlation coefficient = -0.610, p < 0.01) with time since publication. Ouranalyses demonstrate the broad reach of the JDR and the dynamics in citation patterns andresearch agenda over its 100-year history. There is considerable evidence of the inequality inresearch output, if measured via citations, across the globe. Moreover, it remains unclear howpatients’ priorities and dental healthcare needs are aligned with the perceived influence ofsingle research pieces identified by our search. Our findings may help to inspire future researchin tackling these inequalities and highlight the need for conceptualizing research priorities.
