Abstract in English
Aim of Study : The objective of this study was to compare the shaping ability of
ProTaper Rotary instruments(Universal,Next) ,Hand ProTaper instruments and traditional
hand instruments in long oval-shaped root canals.
Methods and materials: Forty human teeth with long oval-shaped root canals were
sectioned at one level in the apical third far 3 mm at the apical root . A modified Bramantetechnique
was used and analyzed changes in root canal in surface area (ΔA), under (10)
magnification. Where the sample was divided into four subgroups each one contains
(N=10) teeth and prepares by one of the four instrumentation systems. The morphological
changes were analyzed by software Program (Auto Cad 2013).
