Subject: [roots] my endo "failure" of the month

well, here is a case i treated 7 months ago, and now she 
came to me with a nice vertical root fracture.

just take a look at the nice occlusal interferences in 
lateral movement this crown has....... (you have a youtube 
link here: http://www.youtube.com/watch?v=mfgHdrdh6Qs )

so, who's fault should be this case?:) - Sergiu



Sergiu, I think itís nobodyís fault. Itís bad luck, you did 
a good job, and it looks nice. On the First photo you just 
see pariodotitis apicalis at the apex and nothing along the 
root, so no sign of fracture there.

This could probably be a case for the CT scan! - Rob Kroese

I'm sorry, but I think the fracture was there originally.  
It was a problem in not catching it at original diagnosis.   
To my eye, it can be seen on your finish film.

Pretty tough to lay blame on the crown when they will 
occasionally supererupt with the lesion and change their 
position.  The video shows group function with the canine 
- Craig Harder

Well, Craig, i had a bad feeling about this one right at the 
beginning, so i double checked for a vrf before and after the 
rct, that area included. So i am sure that line wasn't there 
when i,ve finished. Maybe the video is not that good, but 
i've seen an early involvment of the bicuspid in lateral 
movement, right before the canine was takeing in. Ah, and the 
patient told me that she felt the crown 'high' for a week or 
so after luting. I'll be back tomorow with some clinical pics from
the treatment, including staining . Thanx, Sergiu

I must have read your attachment wrong.  Thought that the date 
on the second pic you circled was from last year.Bad situation.
I hate bicuspids for this reason (along with lateral incisors)
