Apico on MTA case

Subject: [roots] Apico on MTA case

Doesn't happen very often, but once in a while a lesion on 
an immature tooth doesn't heal after a conventional
rct with an MTA plug.

This 15 year old boy sustained a trauma at the age of 7. 
I found it remarkable that the root tip seemed to be
completely developed, but the canal walls remained 
underdeveloped. Another remarkable detail was that there
was a sinus tract present, but all front teeth responded 
to cold and EPT. I did a conventional rct 2.5 years ago.
Upon entry I found the pulp of 11 to be necrotic. The 
root tip appeared to be permeable, I was able to penetrate
it with handfiles on several places. These barriers can be 
incomplete and often have a Swiss cheese appearance.
You can also see the extrusion after application of 
Ca(OH)2. I placed an MTA plug, a post and a BU of composite.

After 2 years, there was still a lesion. We did surgery, and
saw him a few days ago for 6 month recall postsurgery.
Must have been an extraradicular biofilm... What else could 
have caused the persistent lesion?

21 has PCO, but responded to cold and EPT, so I recommended 
no treatment - Marga

How do you keep the bone so photographically pristine? When I take surg photos through the scope, especially in posterior areas it usually looks like a red washed out bloody mess. - Terry I guess I usually delete pics showing red washed out bloody mess....:-)) - Marga Easy. She uses a laser. - Patty Patty, I didn't know we knew each other... - Marga How do you keep the bone so photographically pristine?

This is because there is no turbine to spray things around just a fine mist of water and that the erbium actually tends to block out some of the bleeding that occurs at the bone . It is interesting to see this and at times after you are done you actually have a very clear view of the crypt. - Glenn Marga, did you just "shave" MTA plug? Or did you remove some of the MTA plug and placed a new MTA retro-filling? Duying to your flap design and suturing :-))) - Dmitri
