| Abstract Scope |
Understanding the interaction at the interface between the resin composite filling material and the natural tooth is one of the great challenges in dental related materials innovation today. This study aims to develop better tools for evaluating dental composite material properties. and performance in a more clinically relevant approach. This objective is accomplished by evaluating X-ray CT generated images of ex vivo samples of extracted human teeth under various conditions. Samples were prepared with Class I caries lesions, filled with off-the-shelf resin composite filling materials, then 3D imaged at various compressive loads and accelerated aging levels. These 3D images reveal the distribution and location of voids and shrinkage throughout the material phases and interfaces generally, along with a more experimental approach of Volume Image Correlation (similar to Digital Image Correlation) to measure internal stresses under true in-service conditioning. |
