3D Mapping of Polymerization Shrinkage Using X-ray Micro-computed Tomography to Predict Microleakage

摘要

ObjectivesThe objectives of this study were to 1) demonstrate X-ray microcomputed tomography (μCT) as a viable method for determining the polymerization shrinkage and microleakage on the same sample accurately and non-destructively, and 2) investigate the effect of sample geometry (e.g., C-factor and volume) on polymerization shrinkage and microleakage.
