Q. Do you have a tape series on how to use MTA? I love the material, but have trouble with placement. Have you come up with a solution to this problem?
A. MTA, commercially known as ProRoot, may be carried into the field with various devices. A relatively new device that has come to market is the Dovgan carrier (Quality Aspirators) which I have found particularly useful in placing ProRoot. In addition, the Ruddle on Retreatment
DVD entitled "Management of: Blocks, Ledges, Transportations & Perforations" has an excellent section on the mixing and handling of ProRoot.
