(a) Laboratory µCT images of the entire root length and a part of the crown lacking sufficient contrast to show the difference between some of the materials or to depict gaps at their interfaces. (b) PCE-CT revealed extensive details in the structure of the restoration, showing the morphology of the tooth and the presence of the adhesive layer (white arrows), as well as details within and the difference between the fibreglass post, self-adhesive resin cement (SARC) and the resin composite of the crown.
