- 5. The composition of claim 4, further comprising a polysaccharide selected from the group consisting of cellulose, ethylcellulose, carboxymethyl hydroxyethylcellulose, cellulose acetate propionate carboxylate, hydroxyethylcellulose, hydroxyethyl ethylcellulose, hydroxypropylcellulose, hydroxypropyl methylcellulose, methyl hydroxyethylcellulose, microcrystalline cellulose, sodium cellulose sulfate, and mixtures thereof.
- 6. The composition of claim 5, further comprising a luminescent compound.
- 7. The composition of claim 1, wherein the at least one compound selected from the group consisting of (i) polysaccharides or (ii) phospholipids comprises a phospholipid compound.
- 8. The composition of claim 7, wherein the phospholipid compound is selected from the group consisting of lecithin and derivatives thereof.
- 9. The composition of claim 2, further comprising a phospholipid compound.
- 10. The composition of claim 9, wherein the phospholipid compound is selected from the group consisting of lecithin and derivatives thereof.
- 11. The composition of claim 1, wherein the phospholipid is selected from the group consisting of lecithin and derivatives thereof, and wherein the polysaccharide is selected from the group consisting of cellulose, ethylcellulose, carboxymethyl hydroxyethylcellulose, hydroxyethyl ethylcellulose, hydroxypropylcellulose, hydroxypropyl methylcellulose, methyl hydroxyethylcellulose, microcrystalline cellulose, sodium cellulose sulfate, and mixtures thereof.
- 12. The composition of claim 10, further including a luminescent compound.
- 13. The composition of claim 1, wherein the at least one compound selected from the group consisting of (i) polysachharide or (ii) phospholipids provided in a minor amount relative to the amount of the combined amounts of the lac resin and solvent.
- 14. The composition of claim 1, wherein when the at least one compound selected from the group consisting of (i) polysaccharides or (ii) phospholipids is a polysaccharide, the polysaccharide is present in a range of up to about 4.75%, and wherein when the at least one compound selected from the group consisting of (i) polysaccharides or (ii) phospholipids is a phospholipids, the phospholipid is present in a range of up to about 1.5%.
- 15. The composition of claim 3, wherein the ethylcellulose is present in an amount of from about 4.25% to 4.5%.
- 16. The composition of claim 8, wherein the lecithin and derivatives thereof are present in an amount of from about 0.09% to 1.0%.
- 17. The composition of claim 1, further comprising a treatment agent.
- 18. The composition of claim 17, wherein the treatment agent comprises a fluoride containing compound.
- 19. A method for altering the appearance of teeth comprising the steps of:
a) preparing the tooth by exposing the tooth so that the tooth to be treated is exposed; b) preparing a lac based covering compound containing a lac resin, a solvent, a pigment and at least one compound selected from the group consisting of (i) polysaccharides or (ii) phospholipids; c) applying the covering compound prepared in step (b) to the tooth surface to be coated; and d) allowing the covering compound applied to the tooth to dry by exposing the tooth to air.
- 20. A method of making a design or other indicia on a tooth comprising the steps of:
a) providing a masking material having a design or indicia formed by an aperture cut into said masking material; b) providing adhesion means for temporarily adhering the masking material onto a tooth surface, c) attaching the masking material to a tooth surface; d) providing a covering compound for application to a tooth surface, wherein the covering compound comprises:
i) a lac resin; ii) a solvent; iii) at least one compound selected from the group consisting of (i) polysaccharides or (ii) phospholipids; and iv) a pigment; e) applying the covering compound over the masking material to cover the tooth surface which is accessible through the apertured design or indicia of the masking material; f) allowing the covering compound to dry; and g) removing the masking material from the tooth surface.
