Reversible addition–fragmentation chain transfer (RAFT)-mediated polymerization has been implemented in commercially available bulk-fill dental composites, with the idea of either optimizing at depth, while providing sufficient opacity, or reducing exposure time. The elastoplastic and viscoelastic behavior materials pursuing both ideas are described comparatively connection microstructure artif...

Introduction: Aging is a natural phenomenon that is caused by changes in the cells of the body. Theoretically, aging starts from birth and lasts throughout life. These changes affect the function of the cells. Also, in old tissues, the capacity for homeostasis and tissue repair is decline due to destructive changes in specific tissue stem cells, niche of stem cells and systemic factors that reg...
