Use cotton gauze to collect the bits of decay so that the person does
not swallow them. Use your mirror and look closely around the edges
of the cavity for any decay that you may have missed. Put some cotton
inside the cavity and leave it there to keep the area clean and dry while
you mix the filling.
3. Mix the cement on a piece of smooth glass. Place separately onto the
glass a pile of zinc oxide powder and a few drops of eugenol liquid.
Pull a small amount of the powder to the liquid with the mixing tool
and mix them together. Add more powder in this way, until the cement
mixture becomes thick.
Suggestion: P ractice mixing the cement ahead of time.
You can then find out the time it takes to become hard.
Cement is much easier to use when it is
thick and not too sticky. Roll a bit between
your fingers. If the cement sticks, it is not yet
ready. Add more powder and then test again.
Now take the cotton out of the cavity. Check to
be sure the cavity is dry. If the cotton around
the tooth is wet, change it.
