This study aimed to compare the amount of debris extrusion of four endodontic systems made of Nickle-Titanium alloy. This in vitro study was done on 80 extracted primary molars. They were selected by cone-beam computed tomography and randomly divided into four groups (n = 20) to be prepared to the apical size of 25 by one of the systems: Reciproc, Protaper Universal, Neolix, or Hyflex CM. Debris was collected into Eppendorf microtubes and placed in an incubator to evaporate the washing solution. Debris was weighed by a digital scale of 0.01 g precision. Data were statistically analysed using SPSS software. Tukey’s comparison was used to determine the difference between the four file systems (a = 0.05). Debris extrusion after Reciproc preparation (0.00320) was significantly higher than the other (P 0.05), with no significant difference having been observed among the other systems (P 0.05). It can be concluded that all systems under investigation exhibited debris extrusion.
