About gutta percha points
Gutta percha is made from the coagulated sap of certain tropical trees; the FDA classifies it as a Class I device, softened by heat, put into the canal and hardening as it cools (21 CFR 872.3850). A point is mostly not gutta-percha: a stated composition is 20 percent gutta-percha, 56 percent zinc oxide filler, 11 percent barium sulfate as radiopacifier and 3 percent plasticizers. It becomes soft at 60 degrees Celsius and melts at around 95 to 100 degrees with partial degradation. Points come standardized, matching the taper and apical gauge of the instruments, or non-standardized with a variable taper whose tip is adjusted after gauging.
The solid core of the filling, which has no adhesion to the canal wall on its own. Its thermoplastic nature and strong adherence to the dentine walls make complete removal difficult if the canal is ever retreated.
