Mineral Trioxide Aggregate - Usage in Some Clinical Cases - Internal & External Root Resorption & Obturation

Internal & External Root Resorption & Obturation

In internal resorption… root canal therapy is performed, putty mixture of MTA is inserted in the canal using pluggers to the level of the defect. Gutta percha and root canal sealer are placed above the defect to complete the root canal treatment. In direct cases, the canal may be completely obturated with MTA. The MTA will provide structure and strength to the tooth by replacing the resorbed tooth structure. In external resorption… after root canal therapy is performed. Flap is raised over the tooth and the defect removed from the root surface with a round bur. Retrograde application of MTA to the root surface is then completed.

Famous quotes containing the words root, internal and/or external:

    A radical generally meant a man who thought he could somehow pull up the root without affecting the flower. A conservative generally meant a man who wanted to conserve everything except his own reason for conserving anything.
    Gilbert Keith Chesterton (1874–1936)

    The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.
    Gerald M. Edelman (b. 1928)

    The soul, he said, is composed
    Of the external world.
    Wallace Stevens (1879–1955)
