The Temperature Dependence of Micro-Leakage between Restorative and Pulp Capping Materials by Cu Diffusion

Fig. (5) (a) 3D Micro-CT images of the unprocessed sample which the outer side is restorative material and the inner side is pulp capping material and (b) 3D Micro-CT images of the sample which exposed to copper. (image has white intense regions shown by the black arrow due to Cu treatment on the surface).
