finding mb2 and mb3:) well, I like to search the entire
istmus, check this surprise i had today - Sergiu
Nice Sergiu. As the late great Dave R said the last time
I heard him lecture, when speaking of a situation
like yours, "I'm not a canal counter, so I just trough
away the isthmus to create one canal" I thought that
was pretty funny - Mark
Dave R is so right. is more than right. I bet that every
rooter has the highest failure percentage on mesial roots
(upper or lower molars) And this is becous those damn isthmuses.
Yes, some times we manage to dig holes , we use to call
them middle mesials, mb2s mb3s, p2 and we feel joyfull about
that and we publish our "nice cool extra anatomy case" on
roots but even if we would dig holes on a daily basis as
mb2 mb3 mm, would that be enough to desinfect the entire
root canal system?
I bet it is not enoughm it will never be enough.
But that's life. Nothing is 100% predictible - Sergiu
sergiu , the blue composite provides nice contract for pics,
and nice documentation as usual, what was the preparation size
in all and is the case packed yet, would like to see the
