CURETTE McCALL 11A/12A 224520

For the removal of sub-gingival calculus and root cleaning. Universal curettes can be used in any area of the mouth with a semicircular tip used at 90° to the root surface of the tooth. Sharpened on both sides of the blades.
Designed to adapt to all teeth surfaces to be treated. Sharpened on both sides. Blades/Cutting Edges perpendicular (90°) relative to the shank. Round back (semi-circular cross section) and round tip/toe for a less traumatic subgingival cleansing. Sharpening: Curettes: curettes have a rounded toe, so the position of the Sharpening Stone is adapted around the rounded cross-section. 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.
