Preparation of bovine and human root canal models. Bovine roots were sectioned longitudinally and the root canal surface was treated with a rose-bur (a). Additionally, human roots were cut horizontally into 2 mm thick discs after root canal preparation (b). Both models underwent ultrasonic desorption to remove the accumulated „smear layer“(abrasive dust, debris).
