Claims21
A strip for transferring a therapeutic composition to a tooth comprising:
- a backing layer;
- and
- at least one therapeutic composition;
- said therapeutic composition is arranged in a discontinuous micro-pattern on said backing layer;
- wherein said backing layer is substantially water insoluble and has a series of pits filled by said therapeutic composition;
- and
- wherein said therapeutic composition has an adhesion property that has a lower release strength from said backing layer than adhesive strength to a tooth such that contacting said tooth with a portion of said at least one therapeutic composition transfers said portion of said at least one therapeutic composition from said backing layer to said tooth.
A method for transferring therapeutic compositions to a tooth, the method comprising acts of:
- filling a series of pits in a device comprising at least a backing layer with at least one therapeutic composition having an adhesion property that has a lower release strength from said backing layer than adhesive strength to a tooth, said therapeutic composition arranged in a discontinuous pattern on said backing layer;
- bringing into contact the device with at least one tooth such that a portion of said therapeutic composition comes into contact with said at least one tooth;
- removing said backing layer;
- wherein contacting said device with said tooth transfers at least said portion of said therapeutic composition onto said tooth such that said portion of therapeutic composition that is in contact with said tooth remains on said tooth when said backing layer is removed.
