In the present work, three heats of Si-Mo-Cr ductile cast iron with varying amounts major alloying elements are produced. The effect microstructural features on microhardness, tensile strength and ductility is studied. Increasing nodule count decreases pearlite-ferrite ratio, which results in a decrease but an increase percentage elongation. spherical plays significant role arresting crack reor...

Abstract Background Infiltration and sealing are micro-invasive treatments for arresting proximal non-cavitated caries lesions; however, their efficacies under different conditions remain unknown. This systematic review meta-analysis aimed to evaluate the caries-arresting effectiveness of infiltration further analyse across dentition types risk levels. Methods Six electronic databases were sear...
