OBJECTIVE The present study aimed at a better understanding of the internal shrinkage patterns within different cavity sizes. METHODS Ten cylindrical cavities in two sizes were filled with a flowable composite and scanned using X-ray micro-computed tomography (μ-CT) before filling, before and after polymerization. Three-dimensional (3D) non-rigid image registration was applied to sets of two subsequent μ-CT images, before and after polymerization in order to calculate the displacements and… CONTINUE READING
