Abstract
This study aim to compare the root surface morphology after scaling with Gracey’s curette, ultrasonic tip, Periotor insert, using Atomic Force Microscopy (AFM). For every tooth have been analysed three different zones on the surface and for every zone we investigated concentric foursquare areas with the size of 0.5 / 1 / 2 / 5 / 10 / 20 mm. For every area, bi-dimensional-2D and three-dimensional-3D images, phase contrast and statistical parameters have been registered. Both ways to analyse data: directly, by the images comparing and the statistics revealed a more appropriate surface morphology obtained after scaling with Periotor inserts, followed by Gracey’s curette and ultrasonic tip, which were approximately simillar in features.
