The aim of present study was to investigate and compare the oscillation ampltude of experimental ultrasonic scaler tips made of following four different metal; copper(CU), bronze(BR), 316L stainless steel(316L) and conventional stainless steel(SS). These experimental metal tips were connected to the ultrasonic equipment that was set at 40% of full power, the oscillation amplitude of tips was measured using a piezoelectric sensor connected to an amplifier and an analogue-digital converter. The measurement was repeated under various loads from 10g to 60g. In general the oscillation amplitude of the CU and BR group was significantly lower than that of 316L and SS group(p<0.05). The CU and BR group showed a significant difference when the load was more than 50g(p<0.05). The 316L and SS groups showed no significant difference in all loads(p>0.05). And the oscillation amplitude was significantly increased in the all groups according to the increase of the load(p<0.05).
