초록

Objectives: This study aimed to evaluate the effect of different types and angulations of ultrasonicscaler tips on the surfaces of denture base resins.
Methods: Heat-polymerized and computer-aided design/computer-aided manufacturing (CAD/CAM)denture base resin specimens were manufactured in rectangular shapes (60×10×3 mm) and dividedinto four groups. Stainless-steel and carbon scaler tips were applied at angles of 0° and 45° with 100g of weight for 60 seconds, and the depth and volume of the surface defects were compared.
Results: Stainless-steel tips with a 45° angle showed a larger defect depth and volume than stain less-steel tips with a 0° angle and carbon tips with a 0° angle (P<0.001). No result was observedwhen using carbon tips with a 45° angle because the scaler tip broke during the experiment. Nosignificant differences were observed between the heat-cured and CAD/CAM resins at 0° angles.
Conclusions: Within the limits of this study, as the angle of the scaler tip increased, the depth andvolume of the defect increased. And, when the angle was 0°, no significant differences were ob served between the effects of the stainless-steel and carbon tips.
