- Disputes over the use of teflon in dentistryPublication . Attardi, Elisa; Pereira, JorgeTeflon (ptfe) is a widely used material for a wide range of applications thanks to its very stable chemical composition that gives it considerable physical-chemical capabilities such as its great chemical and thermal stability, its low surface energy, insolubility in organic fluids, making it an ideal choice in many areas. However, it would seem that perfluoroacyl compounds (PFC's) are incapable of degrading, demonstrating the tendency to bioaccumulate and biomagnificate. This would make them persistent pollutants in the environment compromising global health. Since it is also widely used as a medical and dental device, it is necessary to evaluate the risks that choice in the use of this material may result in clinical choices once the behavior of materials containing a high amount of fluorine would seem to interact negatively with materials widely used in medicine, like titanium.
