Abstract

Abstract A syringe system for matching tooth composite colors to natural tooth colors. The system includes a plurality of delivery syringes each having therein a different colored tooth composite. In one embodiment, a visible portion of each delivery syringe is colored with the same color as the tooth composite within that delivery syringe. In another embodiment, an actual cured sample of the tooth composite contained within the syringe is placed on a visible portion of each delivery syringe. Therefore, matching tooth composite color to natural tooth color can be performed by simple viewing of the delivery syringes. An organizer displays the delivery syringes in such a way that the colored portion, or composite sample portion, of each delivery syringe is clearly visible. The organizer means also displays the delivery syringes in such way that the delivery syringes together provide a visible palette of colors from which to choose a matching tooth composite.
