Universal Curettes
Columbia 4R/4L Universal Curettes are designed for moderate calculus removal on supragingival and subgingival tooth surfaces. The blade of a Universal Curette has a round toe and back, and two cutting edges for scaling, making it an efficient design for scaling the entire mouth. Universal Curettes are also available with rigid shanks in select patterns for moderate to heavy calculus removal.
2 Apply strokes to remove deposits from the centerline of the tooth to the proximal surface. Work from canine to canine. 3 Switch working ends and repeat for surfaces away from you. 4 Repeat all of the above for the lingual surfaces. D Anterior Universal Instrumentation Sequence To Scale The Facial Surfaces: 1 Place the toe of the blade toward the proximal surface with the handle parallel to the tooth.
Posterior Universal Instrumentation Sequence 1 Begin at the distal line angle of the most posterior tooth. Direct the toe of the blade toward the distal with the terminal shank angled slightly toward the tooth. 2 Apply strokes from the line angle to the contact area. 3 Turn the toe toward the mesial to scale the buccal and mesial surfaces. Continue this sequence to complete the posterior region. 4 Switch ends and repeat from the lingual aspect.

Instrumentation The correct working end for scaling is evident when the toe is directed interproximally and the terminal shank is parallel to the tooth. To remove deposits, the cutting edge is applied to the tooth surface and the facial surface of the blade is tilted toward the tooth to achieve an approximate 85° angle between the tooth and blade. Apply lateral pressure against the tooth and pull upward while maintaining contact with the tooth. Our popular Universal Curettes are available in the Lavender Resin 8 Colors Handle!
