Portland cement: A Building of Evidence for Clinical Use
Mineral trioxide aggregate (MTA), has been successfully used in difficult endodontic situations such as immature pulp less teeth and vital pulp therapy. Portland cement (PC), which forms the bulk of MTA, has been reported to exhibit similar properties. The physical properties and biocompatibility of PC has been researched in vitro and on animals, with a few studies on humans as well. This artic...
متن کاملInjectable citrate-modified Portland cement for use in vertebroplasty
The injectability of Portland cement (PC) with several citrate additives was investigated for use in clinical applications such as vertebroplasty (stabilization of a fractured vertebra with bone cement) using a syringe. A 2-wt % addition of sodium or potassium citrate with PC significantly improved cement injectability, decreased cement setting times from over 2 h to below 25 min, while increas...
متن کاملEffect of Use of Granulated Slag Instead of Portland Cement on the Properties of Concrete
In this research, 210 concrete cube specimens (15cm) were made replacing 0, 5, 10, 15, 20, 25, 30, 35, 40, 50, and 60 percent of slag powder from Isfahan Steel Mill for cement. The control specimens were made with 350 kg/m3 cement content and the water cement ratio in all specimens was 0.51. The Slump value and compressive strength of concrete specimens in 7, 28 and 90 days were obtained and th...
