The purpose of this study was to evaluate the sealing ability of Portland cement and MTA in comparison to amalgam as retrograde filling materials by utilizing three different root - end preparatory methods ( Laser , ultrasonic and conventional techiques ) . One hundred and twenty eight teeth were used divided into three main experimantal groups (n=36) : (1) diode laser preparation (L) (980nm 8 w\10 sec.)
