In case of foul smell present in root canal but no oozing can we seal it with BC Sealer or other sealer.

What are the conditions that is favorable for root canal obturation & conditions not favorable for root canal obturation.


In our college, our teacher tell us the following points. Is it correct or not.

Discuss the Stage at Which the Tooth is Ready for Root Filling.
Or, Conditions Observed Before Obturation:

The tooth should be asymptomatic
The dressing should be dry
Absence of foul smell
Absence of peri-apical sensitivity on percussion
No oozing should be present
A smooth & tapered preparation of the canal
Healing of the sinus track

If RWE show us a video lecture on when to fill or not fill the root canal, it will be a favored for us.

Thank u for ur Co-operation & the videos that RWE share with us.

In reply to MD. HOSSEN This is a great question and probably worth a Friday Question video. 
To make a long story short, I think you have a very good teacher who cares about improving your success rates. But this strict criteria for success may not be necessary. While you can not go wrong by following your teacher's advice, there's the question of how to we know what we know? Anyway. We don't think your teacher is wrong; but some of the tests such as absence of periapical sensitivity on percussion and absence of foul smell can be questionable. I think this would make a good tutorial. :)

In reply to MD. HOSSEN It's very subjective. How do you know where the smell is coming from? patient's breath? The area? I wouldn't stick my nose in the patient's tooth, would you?!

In reply to Dennis Brave Dr. Dennis Brave, it not like that what u are thinking. In a case like acute or chronic abscess, before obturation i dry the canal & before obturation i insert dry paper point for confirmation of the canal is dry or not & smell the paper point, as in abscess case after insertion of paper point or thin cotton roll in K-file i found the canal smell bad.

In reply to MD. HOSSEN I guess it doesn't hurt to medicate such canal one more time. But we've been doing single visit therapy for many years and have not had any problems. As long as you have a large enough apical diameter and have done a good job disinfecting the canal I'm not sure if the smell test is scientific enough to pass. But then again, as long as the patient doesn't mind coming back, I don't see a problem with doing more to disinfect than less.
