From the chair to the lab and back: will revealing invisible endodontic challenges help find new solutions?

 

  • On the merits of seeing more, using laser-like X-rays 
  • Mind the gap: synchrotron-based micro CT breaks the micron barrier 
  • Shedding new light on endodontic challenges with contemporary root filling systems



Abstract

X-rays are essential for endodontic diagnosis. X-ray imaging is increasingly implemented in 3D imaging configurations such as CBCT for clinical use and micro CT for research purposes. Modern synchrotron light-sources provide laser-like coherent X-rays that can be used to produce contrast between areas of similar density, where interference patterns disclose structural inhomogeneities. For example, such interactions of X-rays with root fillings reveal significant details and micron sized gaps. This makes it possible to investigate the boundary between the root canal filling and root dentine in exquisite detail and at high resolution.

This presentation will showcase endodontically important observations based on this methodology, and will present the advantages, disadvantages and possible clinical relevance. Ongoing potential benefits to endodontic research will be discussed. Examples of scanning of novel filling materials will be shown, demonstrating their interfaces and characteristics and exploring new endodontic dimensions, stemming from high resolution, large data.

 

Curriculum Vitae

Dr. SeokWoo Chang has completed his postgraduate education from Seoul National University in 2002. After his resident training at the Seoul National University Dental Hospital, he became first full time lecturer and then Assistant professor at the Institute of Oral Health Science, Samsung Medical Center, Sungkyunkwan University School of Medicine. Since 2014, he is Associate Professor at the Department of Conservative Dentistry, Kyung Hee University School of Dentistry, Seoul.


His main fields of research include NiTi instrument fracture tests, differential scanning calorimetry, SEM and TEM analysis, rheological properties and biological properties of Root Canal Sealer. He has published articles and papers on the Biomineralization characteristics of Mineral Trioxide Aggregate, Effect of substances which can enhance the biocompatibility, angiogenetic ability, and hard tissue forming ability of Mineral Trioxide Aggregate and root Canal Morphology.
