Subject: [roots] Attempt
Here was an attempt at placing MTA at the apex of the distal root. Thought I had it and after a week, I filled with
Epiphany using System A. Blew Sealer and maybe a bit of Resilon by the plug. May have displaced the plug BUT we
appear to have healing. Never know. I'm now more concerned about the mesial root. Small mesial canals and a huge
figure 8 distal. These are 2/07 and 6/07 shots...four month follow up. Guy

Recently i ve been doing lots of such work and i find the barrier technique very effective in such cases.
I usually use either calcium sulphate or tricalcium phosphate barriers and apart from providing a firm surface to
condense the mta plug against , it also aids in proper sealing of the apical third and prevents mta from getting
displaced in the peri -apical region. and being resorbable and osteoconductive these materials can be safely placed
in the bone too - Shantun Malhotra
Hi Shantun, I have seen others talk about this and post cases using these barriers but I have never used them.
Could you please describe the technique and materials used? - Arturo
The barrier method , is simple application of highly biocompatible biomaterials such as calcium sulphate or calcium
phosphates , which apart from providing a matrix against materials such as mta could be condensed also have added
benefits such as osteoconductivity and resorbable nature.
it deals with condensing a putty like consistency of these materials ( after placement in apical third,by using a
dovagan carrier,etc)in the periapical region by using hand pluggers, finger pluggers or even a file works at times!!
till u get a resistance at the correct working length . this placement can be verified radigraphically too.
this creates a firm and feasible surface for application of an mta plug ,which we can be sure of wont get displaced
apically.\ also as these materials are resorbable and osteoconductive so there is no concern of these materials
getting overfilled in periapical region. - Shantun malhotra
