Effect of Different Instrumentation Techniques on Vertical Root Fracture Resistance of Endodontically Treated Teeth
STATEMENT OF THE PROBLEM Vertical root fractures are catastrophic events that often result in tooth extraction. Many contributing factor are associated with increasing incidence of vertical root fracture. Root canal preparation is one of the predisposing factors which can increase the root susceptibility to vertical fracture. PURPOSE The aim of this study was to compare the effects of three d...

متن کاملFracture Resistance of K3 Nickel-Titanium Files Made from Different Thermal Treatments
The purpose of this study was to compare fracture resistances of K3 nickel-titanium files made from different thermal treatments. K3 (SybronEndo, Orange, CA), K3XF (SybronEndo), and experimentally heat treated K3 (K3H) were used. For the cyclic fatigue test, the samples were rotated with up-and-down motion in the artificial canal with the curvature of 60 degrees until the fracture occurred. The...
متن کاملEffect of different nickel-titanium rotary files on dentinal crack formation during retreatment procedure
Background. The aim of this study was to compare the dentinal defects caused by Reciproc, TF Adaptive and ProTaper Next NiTi rotary file systems during the retreatment procedure. Methods. A total of 150 mandibular incisors with straight and single root canals were included in the present study. All the root canals were prepared up to an apical diameter 0.40 mm using stainless steel files. Thirt...
متن کاملThe Effect of Autoclave Sterilization on the Fracture Resistance of ProTaper Rotary Files
Background and aim: The purpose of this study was to evaluate the effect of autoclave sterilization on the fracture rate of ProTaper instruments (ex vivo). Materials and methods: One hundred shaping and finishing ProTaper instruments were used in a crown – down technique for cleaning and shaping the mesial canals of extracted mandibular molars using 5.25% NaOCl for irrigation. In the e...
