The International Endodontic Journal is a leading international forum for publications in the field of endodontology. We publish research on the health, injuries to, and diseases of the pulp and periradicular region, and their relationship with systemic well-being and health. We are published on behalf of the British Endodontic Society and an official publication of the European Society of Endodontology, Danish Endodontic Society, and Irish Endodontic Society.

Editor-in-Chief of the International Endodontic Journal
Dr Hal Duncan BDS, FDS RCS, FFD RCSI, MClin Dent, MRD RCS (Endo), PhD
Professor Hal Duncan has been the Editor-in-Chief of the International Endodontic Journal from 1 January 2022. His academic background is that he received his dental degree from the University of Glasgow and his endodontic speciality training in Guy’s Hospital, King’s College London. For ten years, he worked part-time in specialist referral endodontic practice. He completed his PhD in the University of Birmingham (supervised by Professor(s) Tony Smith, Paul Cooper, Garry Fleming) on the subject of ‘Epigenetic approaches to the role of Histone Deacetylase Inhibitors (HDACi) in promoting dentine-pulp reparative mechanisms’. As an Academic Consultant in Endodontics, he has led endodontic teaching, service delivery and research in Dublin Dental University Hospital (DDUH) for the last 15 years. He has published over 130 international peer-reviewed scientific articles, 60 research abstracts, 19 book chapters as well as editing 3 textbooks. He was the primary author of the recent European Society of Endodontology (ESE) position statement on ‘Management of deep caries and the exposed pulp’ and is the lead for the ‘ESE S3-level Guidelines for the Treatment of Endodontic Disease’. He was been an Associate Editor for the International Endodontic Journal since 2014. Hal has completed three sponsored research fellowships in New York University/Rutgers University investigating the role of epigenetic-modifying agents on tooth development and regeneration as well as receiving multiple research grants as principal investigator. In DDUH, he currently maintains a research pulp biology laboratory and supervises several clinical and scientifically trained PhD students and postdoctoral researchers in basic and translational pulp biology and endodontics. Currently, he is the Director of Research in the DDUH, the President elect of the ESE, a Member of the Executive Board of the ESE, and the President of the Pulp Biology and Regeneration Group of the IADR.
