Review of a new root canal obturation technique.

The relatively new technique of obturation using Thermafil endodontic obturators is claimed by the manufacturers to use gutta percha of a more linear structure than conventional gutta percha, and so provide a seal at least equal to laterally condensed material. In this article the authors describe the practical use of this widely marketed technique. Studies which have so far evaluated this technique are reviewed and its advantages and shortcomings discussed.
