The aim of this in vitro study was to evaluate the changes in the roughness and weight of titanium discs treated with 3 different types of magnetostrictive ultrasonic scaler tip. Eighty identical disks (10 mm in diameter), 50 for surface roughness and 30 for weight change, were investigated in this study. For this study, 3 types of scaler tip were used as follows; Powerline(FSI-PWR-1000), Slimline(FSI-SLI-1000), and Thinsert(-16 00037374). The power was set to high power(HP), medium power(MP), and low power(LP), in the blue zone recommended by the manufacturer. Surface topography analysis was carried out using scanning electron microscopy (SEM). Surface roughness measurements, the average surface roughness (Ra) and mean roughness profile depth (Rz), were compared between treated and non-treated surfaces with a profilometer. A PowerLINE-MP of magnetostrictive ultrasonic scalers for implant patients might be recommended when considering changes in the roughness and weight of titanium discs.
