Combining apical torsional load and cyclic fatigue resistance of NiTi instruments: New approach to determine the effective lifespan of rotary instruments

Autor: Francesco Iacono, Chiara Pirani, Maria Rosaria Gatto, Carlo Prati, Ove A. Peters

Publikováno v: Australian Endodontic Journal. 47:429-434

In the described proof-of-principle experiments, we introduced a novel testing device to investigate how different concurrent torsional loads influence the cyclic fatigue (CF) resistance of a nickel–titanium (NiTi) instrument. The device was design

Reciprocating System for Secondary Root Canal Treatment of Oval Canals: CBCT, X-rays for Remnant Detection and Their Identification with ESEM and EDX

Autor: Andrea Spinelli, Fausto Zamparini, Alessio Buonavoglia, Paolo Pisi, Maria Giovanna Gandolfi, Carlo Prati

Publikováno v: Applied Sciences; Volume 12; Issue 22; Pages: 11671

Aim of the study: to evaluate root filling remnants after secondary root canal treatments (SRCTs) of oval-shaped canals with X-rays and cone beam computed tomography (CBCT). The SRCTs were performed using reciprocating NiTi instruments. Methods: Sing
