Types of Curettes

A curette is a type of scaler that is designed formoderate calculus removal on supragingival and

subgingival surfaces.

Types of Curettes: niversal

All curettes share the same common elements: $ounded bac%

niversal Curettes

niversal curettes are designed foreasy adaptation on all tooth surfaces"thus the name 'universal(#.

niversal Curettes

The blade of a universal curette has a round toe andbac%) and two cutting edges for scaling) ma%ing it anefficient design for scaling the entire mouth.

niversal Instrumentation

The blade is correctly adapted when the toe is directed

interpro*imally and the terminal shan% is parallel to the tooth.

To remove deposits) the cutting edge is applied to the tooth surfaceand the facial surface of the blade is tilted toward the tooth toachieve a +,&-/ angle between the tooth and the blade.

Apply lateral pressure against the tooth and pull upward whilemaintaining contact with the tooth.

Gracey Curettes

In the early ;riedy introduced a set of instruments

designed to be used on specific tooth surfaces

that improve adaptation and deposit removal.

The Gracey 'area specific( designs have laid

the groundwor% for the new instruments of

today.

Today) the Gracey Curette family of

instruments give clinicians many options for

their treatment needs.

Gracey Curettes

The Gracey blade design is offsetfrom the terminal shan% at +,/.

This creates one cutting edge which

is referred to as the lower edge.

The blade of a Gracey Curette is correctly adaptedwhen the lower cutting edge is against the tooth andthe terminal shan% is parallel to the tooth surface beingscaled.

Apply lateral pressure against the tooth "root# and pull

upward) maintaining the parallel shan%.
