complex case treated with oneshape single-use NiTi instrument case report

ABSTRACT

Nickel-titanium rotary files have become a standard tool to shape root canals, but they tend to unexpectedly break because of cyclic fatigue. For this reason, important changes have been combined to make NiTi instruments safer. Today new single-use systems have been introduced for complete root canal shaping with only one file. This case report present a difficult lower first molar with four narrow canals treated with OneShape instrument
