Debris extrusion and foraminal deformation produced by reciprocating instruments made of thermally treated NiTi wires
To evaluate the amount of apically extruded debris, percentage of foraminal enlargement and apical foramen (AF) deformation that occurred during root canal preparation with different reciprocation systems: Reciproc, WaveOne (M-Wire), and ProDesign R (Shape Memory Technology Wire) at two different working lengths (WLs): 0.0 and 1.0 mm beyond the AF. The AF of 120 root canals in 60 mesial roots o...
متن کاملApical Extrusion of Debris Produced during Continuous Rotating and Reciprocating Motion
This study aimed to analyse and compare apical extrusion of debris in canals instrumented with systems used in reciprocating and continuous motion. Sixty mandibular premolars were randomly divided into 3 groups (n = 20): the Reciproc (REC), WaveOne (WO), and HyFlex CM (HYF) groups. One Eppendorf tube per tooth was weighed in advance on an analytical balance. The root canals were instrumented ac...
متن کاملcomparison of apical extrusion of debris by using single-file, full-sequence rotary and reciprocating systems
objectives: during root canal preparation, apical extrusion of debris can cause inflammation, flare-ups, and delayed healing. therefore, instrumentation techniques that cause the least extrusion of debris are desirable. this study aimed to compare apical extrusion of debris by five single-file, full-sequence rotary and reciprocating systems. materials and methods: one hundred twenty human mandi...

متن کاملPhase transformation and deformation behavior of NiTi-Nb eutectic joined NiTi wires
NiTi wires were brazed together via eutectic reaction between NiTi and Nb powder deposited at the wire contact region. Phase transformation and deformation behavior of the NiTi-Nb eutectic microstructure were investigated using transmission electron microscopy (TEM) and cyclic loading-unloading tests. Results show that R phase and B19' martensite transformation are induced by plastic deformatio...
