Program Overview:

Vertical root fracture (VRF) represents a difficult clinical problem to diagnose and treat, being considered one of the most common reasons for tooth extraction. The actual knowledge indicates that VRF starts from microcracks in the radicular dentin, and laboratory studies have linked crack formation to some routine endodontic procedures named root canal preparation and obturation. Most of these studies were performed by using destructive methods, such as sectioning technique. Considering that modern endodontic treatment procedures are basically dependent upon the current-available shaping technology, a comprehensive knowledge of the causal-effect relationship between dentinal microcracks, motor-driven canal preparation and obturation techniques is of paramount importance to predict the optimal safeness of the whole endodontic procedure. Nowadays, technological advances in the field of imaginology may lead to a more thorough understanding on this phenomenon. This presentation seeks to critically appraise the methodological aspects and the outcome involved in the studies of dentinal microcrack formation after root canal preparation and obturation.

At the conclusion, participants should be able to:

  •  Discuss the current scientific status on the subject, addressing the limitations and outcomes related to different assessment methods.
  •  Indicate the methodological reasons that led to the current lack of reliable conclusions on the relationship between dentinal defects and endodontic procedures.
  •  Relate how further advances of the methodological approaches would progress toward determining the mechanism of crack formation associated with root canal treatment

Hagay Shemesh, D.M.D., Ph.D.

Hagay was born and raised in Tel Aviv, Israel and graduated the dental faculty in Jerusalem, Israel in 1990. He graduated from the post-graduate endodontic program in Jerusalem in 2000 and then immigrated to the Netherlands and started teaching the undergraduate endodontic course at the Academic Centre for dentistry Amsterdam (ACTA). He then started his PhD project and graduated in 2009 cum laude from the University of Amsterdam defending his PhD thesis “new insights into the root canal wall”. He is now chair of the Division of Endodontology in ACTA , Program director of the post-graduate endodontic program , Dutch representative to the European Association of Endodontology, and is a member of the scientific referee board of the Journal of Endodontics.

Marco Aurelio Versiani, D.D.S., M.Sc., Ph.D.

Dr. Versiani received his degree in Dentistry in 1992. Since 1994, he has been working part-time in the Brazilian Military Police Dental Department in which, recently, he was promoted with the grade of Lieutenant Colonel. He is a certified specialist in Endodontics (1999), but also in Didactics (1998) and Bioethics (2003). In 2012, Dr. Versiani concluded his Master Degree and PhD studies at the University of Sao Paulo, in which he is currently a Postdoctoral Research Fellow. He has authored 4 chapter books in Endodontics and written more than 50 peer-reviewed papers, being a member of the scientific advisory panel for the International Endodontic Journal and Journal of Endodontics. Dr. Versiani has lectured worldwide focusing on his main research interests that are the influence of root canal anatomy on endodontic procedures using non-invasive 3D X-ray micro-computed tomography, towards the improvement of both chemical and mechanical debridement of root canals.
