Scaler (dentistry)
A scaler is a hand instrument used in prophylactic (preventive) dentistry and is primarily used to remove supragingival concrements ( tartar above the gum line ). In general, however, it can also be used to remove other irregularities that irritate the gums: for example, cement residues, protruding filling edges, foreign bodies.
The tips (working ends) of scalers can be designed differently, but are always sharp.
Anterior scalers are usually tick-shaped or chisel-shaped.
Posterior scalers are often sickle-shaped and, depending on the make, can also be designed differently for the right and left side or the upper or lower jaw.
In order to achieve the required pressure and to avoid injuries to the gums, scalers must be guided close to the end of the work, with the fingers at the same time being supported on the teeth.
Scalers should not be confused with curettes , which are used to remove subgingival concretions (located below the gum line), dead root cement or inflamed tissue from the gingival pocket. (See: Periodontitis )
