Can a non-scaling dental assistant polish with a cup? Can they do sealants?
An assistant can use a prophy cup to polish the coronal, supragingival (above the gumline) portion of the teeth. KAR 71-6-6 requires that before an assistant may coronal polish teeth, they must have received appropriate training from the dentist. An assistant can apply sealant material to the teeth and cure the material as long as the assistant is working under the direct supervision of a dentist.
