SCALER CUMINE 235890

Osteo Trimmer / Osteocarver For the removal of supragingival calculus and plaque from teeth. Scalers are used above the gum line, and curettes are used below it. Use of a scaler below the gum line is likely to damage the gingiva (gums). Designed to adapt to all teeth surfaces to be treated. Sharpened on both sides. Blades/Cutting Edges perpendicular (90°) relative to the shank. Triangular cross section and pointed tip/toe for an easier removal of heavy supra-gingival calculus. Sharpening: Sickle Scalers: sickle scalers have a pointed tip and, therefore, the blade is held straight on the Sharpening Stone as it nears the tip. See more info and details on Sharpening Stone product pages. Sharpening evaluation: Visual inspection of the instrument's cutting edge:

• if the cutting edge is rounded will reflect the light, then it is blunt.
• if the cutting edge is edged will not reflect the light, then it is sharp. Testing the instrument's blade with the plastic Testing Stick:
• if it runs smoothly over the Testing Stick, then it is blunt.
• if it grabs into the Testing Stick and removes small fragments of the plastic, then it is sharp.
