title: Management of the immature apex--a clinical guide.
abstract: The production of an apical barrier prior to the placement of a permanent gutta percha root filling in a non-vital immature incisor tooth with an open apex is a well researched and documented technique. The technique is successful and a very satisfactory root filling can be placed in the tooth. However, dentists seem to have difficulty in achieving satisfactory outcomes.
