The top 100 most-cited articles in dentistry by authors with Italian affiliation

Introduction: Analyzing highly-cited articles can provide a retrospective assessment of research evolution and predict future developments. The aim of this study was to carry out a bibliometric analysis of the 100 most-cited articles in dentistry by authors with an Italian affiliation. Evidence acquisition: All the articles published in journals indexed under the Scopus category "Dentistry" and with at least one author affiliated to any Italian institution were searched in September 2022. The 100 most-cited articles were selected and relevant data were extracted and summarized. The analysis of co-authorship at country level and co-occurrence of keywords was carried out. Evidence synthesis: The 100 most-cited articles were published between 1976 and 2020. The number of citations ranged from 235 to 1683, with a mean of 361. The series included 25 citation classics (>400 citations). The majority of articles were classified as expert opinion/narrative reviews (N.=47). Almost half of the articles refer to three predominant disciplines which were implantology, periodontology and restorative dentistry. Only two articles were single-authored. In 30 articles, all the authors had an Italian affiliation and the US was the most frequent country for non-Italian authors. Only one article was published in journals owned by a non-Italian publisher. Conclusions: The present series of highly-cited articles confirms the important role of Italy in dental research. We found an absence of correlation between the level of evidence and the number of citations and a non-homogeneous distribution of highly-cited papers in the different dental disciplines. The majority of articles included in the series shared international co-authorship and were published in high-impact journals.
