Nano Calcium Carbonate-Thermoplastic polyurethane as a Novel Root Canal Filling Material
|
|
The use of gutta-percha as a standard obturation material has made little changes in the obturation technique. Resilon has been developed as an alternative to gutta percha (GP), but its advantages over gutta percha remain controversial. The aim of this study was to prepare a new root canal filling material from thermoplastic polyurethane (TPU) based on polycarbonate (PCA), with inorganic filler particles (50% wt), calcium carbonate (CaCo3), zinc oxide, calcium hydroxide and barium sulfate.
introducing a cheap and biocompatabile root canal filling materila which make chemical bond with root canal dentin,thus reducing microleage and ensure a succesful root canal obturation with no or very less failure
the prepared material exhibits better mechanical, physical and bonding properties. It appears to have better compatibility than GP, particularly at 21 days and has potential to be used safely as a durable root canal filling material.
