title: [Ultrastructural aspects of root planing: scanning electron microscopy (S.E.M.)].
abstract: The basis of Periodontal treatment is represented by scaling and root planing. The aim of this study was to compare root morphology after the use of three currets: a new Hu Friedy Gracey 7/8, a semi-new Hu Friedy Gracey 7/8, a worn Hu Friedy Gracey 7/8. The research indicates that manual treatment with the new curette is effective in removing tartar but can cause excoriations on the enamel of the tooth. In contrast, the use of the semi-new curette is less damaging and obtains the same results removing tartar without injuring the enamel surface.
