To prepare the post space, removal of root canal filling material is most often done using rotary instruments such as Gates-Glidden burs and parallel sided post drills. Such instruments may be used in conjunction with solvents such as chloroform to soften the gutta-percha (GP).
What is a Thermafil?
Thermafil is a gold standard technique in case of severe curves, double curves, narrow canals and long canals [2, 8, 9] The current configuration of Thermafil includes a central radiopaque plastic core (carrier) surrounded by a gutta-percha layer that will be heated in an electric oven to ensure thermoplasticization.
How do you use Thermafill?
