Endo-resto treatment. Management of confluent canals - Part II
Case evaluation before treatment
In endodontic treatments of teeth with more than one canal, we must allways think about the presence of possible confluences between the canals, there are several methods for their determination.
In this clinical case I will present only one among others, which is performed by inserting a gutta percha and a manual instrument at the same time into the canals where we suspect there are confluences.
With this method we are safer and avoid possible mistakes during the obturation phase.
Dg: Pulpitis acute irreversible
Treatment plan :
Root canal treatment
Pre operative X-ray
Isolation, initial preparation of endodontic access cavity
Detection of confluence in artificial tooth to illustrate the procedure
First we need to put the gutta-percha in the main canal, then with manual instrument ISO 08 or 10 we go into the other canal, in order to detect the level of confluences.
In the gutta-percha will remain some scratches from the instrument, and this confirms the presence of confluences and determines their level
The tooth is ready for obturation after all endodontic procedures
Warm vertical technique
X-ray after obturation
X-ray after Crown cementation
Pre-treatment case evaluation greatly facilitates our work and avoids any errors that may occur during treatment.
Applying methods for detecting the confluences in this cases are inevitable.
If we have a pre-treatment plane, it will reduce the possibility of mistakes and surprises that may occur during the treatment.
