Priapism in COVID-19: A thromboembolic complication.

SARS-CoV-2 (COVID-19) infection is frequently associated with thromboembolic complications. In this case report, we describe the diagnosis and management of priapism as a thromboembolic complication of severe COVID-19.

In vitro failure of crowns produced by two CAD/CAM systems.

Previous laboratory studies have demonstrated satisfactory fracture resistance of all-ceramic crowns placed using a resin-composite luting material and a dentine bonding system. This study investigated the fracture resistance of teeth restored using CAD/CAM technology, namely, Zirconia Based crowns and Cerec produced feldspathic porcelain crowns, both luted with a self adhesive resin luting material (RelyX Unicem Clicker 3M ESPE). Standardized preparations were carried out on two groups often sound, unrestored, maxillary premolar teeth.
