Gutta-percha is the most frequently used filling material for root canal obturation. This thermoplastic material fulfills the main requisites for root canal filling, one of which is to be an easily removable material in cases of endodontic retreatment. The methods used to perform it are mechanical, thermal, chemical, or even an association of them, and also special instruments such as ultrasound instruments can be used.
Gutta-percha endodontic filling points were found to contain approximately 20% gutta-percha (matrix), 66% zinc oxide (filler), 11% heavy metal sulfates (radiopacifier), and 3% waxes and/or resins (plasticizer). The mechanical properties were indicative of a partially crystalline viscoelastic polymerfc material. http://jdr.sagepub.com/content/54/5/921
Most often Gutta-percha cones are composed of a vegetable resin, which lends its name to the product, and they are softened by chemical solvents.
