OBJECTIVES This study examined the changes in hydraulic conductance and ultrastructure of dentine bonded with simplified etch-and-rinse adhesives to oxalate desensitiser pre-treated acid-etched dentine. METHODS Human dentine disks were acid-etched, treated with an oxalate desensitiser (BisBlock, Bisco), and bonded with One-Step (OS), Single Bond (SB), OptiBond Solo Plus (OB) or Prime and Bond...
The configuration factor of adhesive cavities is defined as the ratio of the restoration's bonded to unbonded (free) surfaces. Such a configuration factor was described, on ideal cavities, as having a potential value in predicting the behaviour of the restorations, because it is related to the restoration's capacity for relieving stress by flow. The aim of this study was to measure the configur...
A system-level shake-table test of a two-story low-damage concrete wall building was conducted in 2019. The consisted unbonded post-tensioned (UPT) walls with perimeter frames and different wall-to-floor connections to provide deformation compatibility. results highlighted that the measured lateral strength notably exceeded design value. This over-strength largely attributed compatibility defor...
