Subject: [roots] lateral canal or strip perf?

Just completed this case. No blood on paper points at any point,  no bleeding from within the
canal.  Largest rotary used was F2 always leaning on the outside of the canal,  rest by hand.
Looks like it may be a strip perf, but I wonder if I can see an accessory canal on the pre op?
I'm sure I can see a line of sealer / gp  leading to the blob from the main canal convincing me it's a lateral.

I hope to review in a few weeks as pt. needs 3 other teeth treating.  Look forward to posting the recall rads.

Sadly only three canals though - Bill

Thanks Ben, Does the aetiology affect the management of this?  There is a hole in the root,  does the root know
whether I made the hole or it was there already?  Unless there is communication with oral bacteria then it should
be just fine.  I'll make sure to give cleaning instructions at next visit.  Patient is 55 and has pretty good
bone levels for that age,  so I hope they can be maintained - Bill

Looking for a different answer over here? ROFLMAO. I still think its a lateral...John A Khademi

Strip perf, difficult to avoid because of the particular anatomy - Carmen
