Subject: [roots] Molar endo case

Here is a vital case from this week. The location of the mb2 was not that usual. 
Finding it was easy though because blood was seeping from the entrance due to 
the hyperaemic pulp. Mb root with 2 canals, 2 foramina.
Handfiles, ProTapers, continuous wave. Fire on! - Maarten, Belgium

If you establish a proper glide path (at least ISO 10-15 K-file), you should not fracture an S1 in this kind of canal (where the curvature is in the apical 1/2). I fractured a few S1's in case of a curve in the coronal 1/3 of a tight canal. I would not advocate an F2 for the Mb root this case because this file is rather stiff and may tend to transport the canal apically. Also important: when you reach WL with your rotary file, withdraw immediately! Hope this helps - Maarten Thank you,Maarten for your answer! I prepare the glide path with PathFIle and then I start to work with ProTaper! I'? little frightened to post my case, because in here there are a lot of marvelous endodontists. But I think I'll post a case or two soon! - I love your case, really! How do you negotiate this kind of curvature with ProTaper, because I had several curvatures like this and I've fractured a S1 in one of the canals? And it took me another 2 apointments to get rid of the fractured instrument and I'm a little bit frightened when I see a case like this on the PreOp! - Bojidar Kafelov Beautiful work (as always :) ) Maarten! - RafaŽl
