ABSTRACT:
A powered dental scaler is disclosed of a type which drives a vibrating scaling tip in a circular or ellipsoidal pattern of motion. A scaling tip having working surfaces provided by the edges of an elongated, curved element which has a cross-sectional configuration in the shape of a multi-sided figure, e.g., a triangle or a diamond, is particularly useful with a scaler having this type of vibrational pattern. The scaler tip also has a curved free end portion terminating in a point. These configurations enable a dental operator to conduct important dental cleaning operations with a single hand-held instrument.
