Abstract
This study showed no difference between the use of the "Piezon Master 400", using four different attachments as compared to the "Hu Friedy" Curettes as far the formation of grooves and scratch marks is concerned. Both root planing methods gave rise to a scalloped surface of the root cement. The ultrasonic root planing however showed a more discrete scalloped surface with very small tears and having a hammered appearance. Hand instrumentation showed much wider tears on the root surface structure.
