Scanning electron microscopy (SEM) photomicrographs of the remaining filling materials in the coronal, middle, and apical thirds of the root canal (×1000): after photon-induced photoacoustic streaming (PIPS) (a1 coronal third; a2 middle third; a3 apical third); after passive ultrasonic rinsing (PUI) (b1 coronal third; b2 middle third; b3 apical third); after classic syringe-based irrigation (CSI) (c1 coronal third; c2 middle third; c3, apical third)
