background and aims. current chemical methods may not efficiently disinfect dental stone casts. the aim of this study was to investigate if microwave irradiation is effective for disinfection of stone casts. materials and methods. in this laboratory study, three groups (n = 162) of prepared spherical stone beads as carriers with a diameter of 10 mm were inoculated by separately soaking in three...

Application of ceramic reinforcements is one of the effective and well-known ways to refine the microstructure of brittle metals such as magnesium. In this research, the influence of nano/micro particles of zirconia on the microstructure of cast AZ91 alloy was studied. At the first stage, nano and micro ZrO2 powders were blended through mechanical alloying procedure. In five specimens, the tota...

To reduce the risk of spread of the novel coronavirus (COVID-19), the emerging protocols are advising for less physicianpatientcontact, shortening the contact time, and keeping a safe distance. It is recommended that unnecessary castingbe avoided in the events that alternative methods can be applied such as in stable ankle fractures, and hindfoot/midfoot/forefoot injuries. Fib...
