Subject: [roots] Multiple roots lower premolars of the week.
Here is my most dificult cases of last week. Not so usual anatomy for
my country, multiple roots lower premolars Best regards from Moscow
- Ilya Mer
Ilya, Intresting case and intresting anatomy, can you explain moré
details please. - Dr. Alejandro Podolsky G.
The first endo (44 and 45) was done 4-5 years ago. Under crowns it
survived but patient said the teeth hurt him sometimes. The anatomy
looked like C-shape root. Separate lingual and buccal root, into
isthmus of second premolar I succeeded to find one more canal. 44
with internal resorption in the midroot the lingual root and huge
pulp stone. I had to work four appointments to complete these cases
(and calcium hydroxide for 2 weeks in between). Samee! You are right,
the obturation is a problem. I use Obtura injection technique in
most cases and in these cases as well.
The second case (45) was very difficult. The sealer inserted into
orifices of accessory canals gave a hint that would be simple to
find the entrance. In fact it looked like small closed envelope
on the dentin wall. It cost me 6(!) micropeners to understand the
angle and exact point of entry. It was also 2 visit endodontics
with 2 weeks calcium hydroxide between
visits. - Ilya Mer
