  Background: Rotary biomechanical root canal preparation is usually associated with dentin micro-cracks. Aim: to assess and compare the effect of file systems manufactured with different Ni-Ti technologies on root dentin micro-cracking as a measure for integrity. Materials and methods: seventy single canalled premolar root specimens of equal length were divided into seven equal groups (n=10) according to the canal preparation system used. G1 (Protaper universal), G2 (Protaper next), G3 (Protaper gold), G4 (Vortex Blue), G5 (XP Shaper), G6 (Hand K- files) and G7 left unprepared (control). The specimens were thereafter horizontally sectioned at three levels from root apex and accordingly groups were subdivided into 3 subgroups. Subg1 (3 mm), subg2 (6 mm) and subg3 (9 mm). The root sections were dye stained and examined u.. Read More»
