Publication rate of endodontic posters presented at the congresses of the College of Italian Dental Professors

Introduction: Since 1993, the annual Congress of the College of the Italian Dental Professors (CDUO) has been the most important multidisciplinary event involving all Italian dental schools. The aim of this study was to retrospectively evaluate the characteristics and fate of the posters' abstracts presented in the editions from 2015 to 2019 under the category "Endodontics." Evidence acquisition: Abstracts presented in the category Endodontics from 2015 and 2019 were retrieved from the conference proceedings and reviewed. The following data were extracted: year, title, authors, affiliation, topic and study design. PubMed, Scopus, and Google Scholar were searched to determine if each abstract was subsequently published as a full article in an indexed journal. The publication rate was calculated as well as the independent predictors of publication. Evidence synthesis: 118 endodontic posters from 19 Italian dental schools were assessed. The University of Turin submitted the most, followed by Catania and Rome La Sapienza. "Mechanical Instrumentation" was the most common topic, and 82% of the studies were in vitro/ex vivo. Of the 118 abstracts, 42 (35.6%) were published in full in indexed journals. Research collaboration and affiliation with the University of Catania significantly increased likelihood of publication. The published articles (N.=39) received a total of 1093 citations. Most appeared in the Journal of Endodontics and the International Endodontic Journal. Conclusions: Over one-third of the endodontic abstracts presented at CDUO congresses progressed to full publication in indexed journals, generating a notable number of citations. These results highlight the solid quality of Italian endodontic research and its increasing visibility within the international scientific community.
