Experimental set up and workflow for the leakage study: A Class-I restoration was placed on the occlusal surface of a third molar. The restored tooth was then fixed within a holder with acrylic resin for micro-CT scanning. A baseline scan was first obtained before the restored tooth was submerged in AgNO3. After that, a second micro-CT scan was taken using the same position and operational parameters as for the baseline.
