The aim of this study was to evaluate the preparation time and the amounts of apically extruded debris and irrigant using different nickel-titanium instrumentation systems. Forty-five extracted single-rooted mandibular premolar teeth were selected and divided into three groups. The root canals were instrumented according to the manufacturers' instructions, using a reciprocating single-file syst...
Apical extrusion of debris by supplementary files used for retreatment: An ex vivo comparative study
Effect of Instrumentation Techniques and Kinematics on Apical Extrusion of Debris: An In Vitro Study
The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...
Background/Aim. During retreatment, filling material and debris may extrude trigger an inflammatory reaction of periapical tissues. Resilon? has not been investigated in terms solvent use influence on apical extrusion during retreatment. The aim the study was to evaluate amount apically extruded removal using ProTaper (PT), Twisted File (TF), Hedstrom instruments, with without solvent. Methods....
