Abstract
Methods and related systems for mixing a multi-phase fluoride varnish composition preparatory to applying it to a person's teeth. The method includes the steps of providing a multi-phase fluoride varnish composition including a liquid hydrophobic adhesive phase and a solid fluoride salt (e.g., sodium fluoride) phase that is substantially insoluble in the liquid adhesive phase, and applying turbulence to the multi-phase composition within a closed vessel in order to substantially suspend the solid fluoride salt phase within the liquid hydrophobic adhesive phase while preventing spillage of the composition.

A method for mixing a multi-phase fluoride varnish composition preparatory to applying it to a person's teeth, comprising:
- providing a multi-phase fluoride varnish composition comprising a liquid hydrophobic adhesive phase and a solid fluoride salt phase that is substantially insoluble in the liquid hydrophobic adhesive phase, the multi-phase fluoride varnish composition being contained within a closed vessel;
- and
- applying turbulence to the multi-phase fluoride varnish composition within the closed vessel in order to substantially suspend the solid fluoride salt phase within the liquid hydrophobic adhesive phase while preventing spillage of the varnish composition.
A system for mixing a multi-phase fluoride varnish composition preparatory to applying it to a person's teeth, comprising:
- a closed vessel for holding a multi-phase fluoride varnish composition;
- a quantity of a multi-phase fluoride varnish composition comprising a liquid hydrophobic adhesive phase and a solid fluoride salt phase that is insoluble in the liquid hydrophobic adhesive phase, the quantity of multi-phase fluoride varnish composition being contained within the closed vessel;
- and
- means for providing turbulence to the multi-phase fluoride varnish composition within the closed vessel so as to substantially suspend the solid fluoride salt phase within the liquid hydrophobic adhesive phase while preventing spillage of the varnish composition.
A system for mixing a multi-phase fluoride varnish composition preparatory to applying it to a person's teeth, comprising:
- a closed vessel comprising a hollow cylindrical container including an inner wall;
- a quantity of a multi-phase fluoride varnish composition comprising a liquid hydrophobic adhesive phase and a solid fluoride salt phase that is insoluble in the liquid hydrophobic adhesive phase, the quantity of multi-phase fluoride varnish composition being contained within the closed vessel;
- and
- a plug disposed within the hollow cylindrical container, the plug forming a seal against the inner wall, the plug being slidably disposed within the hollow cylindrical container so as to selectively provide turbulence to the multi-phase fluoride varnish composition within the closed vessel so as to substantially suspend the solid fluoride salt phase within the liquid hydrophobic adhesive phase.
