For calculus removal place one of the cutting edges of the universal curette against the tooth surface. Tilt the instrument toward the tooth to achieve 70° to 80° angle between the tooth and the blade. Apply lateral pressure and activate the curette by using vertical, diagonal or horizontal pull strokes. Both cutting edges of the same curette can be used by simply tilting the instrument one way or the other.
Working end perpendicular to the lower shank
Two cutting edges (red line)
For premolars and molars in the lower jaw.
Langer curettes combine universal curette’s working end with Gracey curette’s shank angulation. Angulations ease access to difficult areas and both mesial and distal surfaces can be treated with the same instrument end.
