Mineral trioxide aggregate (MTA) cement has a composition similar to that of Portland cement (PC). Both are composed of calcium phosphate, calcium, and silicon oxide. MTA, in addition, contains bismuth oxide, which provides radiopacity. MTA is a powder that contains trioxides and hydrophilic particles, which set in the presence of moisture .

There were no significant differences in the pH levels of ProRoot ® MTA and RetroMTA ® throughout the experimental periods (p>0.05). The pH of ProRoot ® MTA varied from 9.93 to 8, while the values for RetroMTA ® varied from 9.93 to 7.9. It is worth noting that the pH of both materials tended to decrease over time ( Figure 3 ).

Slag Cement - Lehigh Hanson, Inc.

Slag cement is as old as iron-making itself. In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s. In the U.S., blends of slag and portland cements were introduced in 1896. Today, slag cement can account for 30% to 50% of the cement ...

Pretreatment with Apoaequorin Protects Hippocampal CA1 Neurons from ...

Ischemic stroke affects ∼795,000 people each year in the U.S., which results in an estimated annual cost of $73.7 billion. Calcium is pivotal in a variety of neuronal signaling cascades, however, during ischemia, excess calcium influx can trigger excitotoxic cell death. Calcium binding proteins help neurons regulate/buffer intracellular calcium levels during ischemia. Aequorin is a calcium ...
