The expanded-function dental assistant (EFDA) can play a
major role in the fabrication and temporary cementation of a provisional crown
or bridge. It is the dentist’s and the EFDA’s responsibility to remain current
with the new provisional materials and techniques that are available. It is
essential that a provisional crown or bridge remain cemented while the fixed
prosthesis is being prepared and delivered to the dental office. When the
patient returns for final cementation of a fixed crown or bridge, the
provisional should be cautiously removed without causing any fracture or harm,
just in case it will need to be recemented if the final prostheses needs to be
sent back to the lab for adjustments and remake.

Charge = (current) x (time)
Charge = (0.4 Ampere) x (2 seconds)
Charge = (0.4 Coulomb/second) x (2 seconds)
<em>Charge = 0.8 Coulombs</em>

Answer:
Who Discovered Gadolinium Gadolinium was only discovered in 1880 by a Swiss chemist called Jean Charles Galissard de Marignac.
Explanation:
When analyzing samples of two minerals which contain small amounts of gadolinium, didymium and gadolinite, he discovered spectroscopic lines that were unrecognisable. Every single element has distinctive spectroscopic lines so he knew he had discovered a new element, and called it gadolinium after Finnish chemist Johan Gadolin.
