In Vitro Comparison of Root Surface Treatment Effect between Root Scaling with Ultrasonic Inserts and Gracey Curette and Polishing with Different Cleaning Pastes

The aim of this study was the morphological evaluation root surfaces subjected to manual (curette) and ultrasonic (conventional diamond tips) scaling. surface then polished with a rubber cup three medium-sized pastes. Ninety teeth were randomly divided into groups 30 different instrumentation: (1) instrumentation Gracey® curette; (2) standard steel tip (Universal Perio S-SERIES: USU, Hu-Friedy, Chicago, IL, USA) at power equal 50%; (3) (Punta Piezo Serie E Scaling, 20%. Each group instrumented in subgroups 10 s polishing pastes medium grain sizes single-dose cups: Ultrapro Tx cool mint medium®; Stomyprox media®; Nupro orange®. Polyether replicas taken from all 90 samples analyzed by SEM evaluate morphology after scaling procedures. All techniques caused an alteration without statistically significant difference, whereas resulted maintenance or improvement texture.
