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


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.
