ABSTRACT:
An applicator system for a powered dental handpiece enables the low RPM controlled application of abrasive tooth compound. The system comprises, in combination, a speed reducer and a mandrel which includes a grooved cylindrical sleeve. The mandrel is made from substantially rigid material so that pressure may be applied to the tooth without deformation of the mandrel and, hence, increased contact surface area between the applicator sleeve and the tooth is prevented. The mandrel further includes a central containment pocket for holding and applying the tooth compound so that both inner and outer portions of the applicator sleeve are operable. A ring-shaped end portion of the applicator sleeve is effective for spot application of the compound.
