1. A method of treating an oral disease, comprising: a) applying on a patient's oral tissue an effective amount of a composition comprising at least one oxidant, wherein the oxidant comprises about 3% to about 16% urea peroxide or about 1% to about 12% hydrogen peroxide; and a fluorescent compound;
1. A method of treating an oral disease, comprising: a) applying on a patient's oral tissue an effective amount of a composition comprising at least one oxidant, wherein the oxidant comprises about 3% to about 16% urea peroxide or about 1% to about 12% hydrogen peroxide; and a fluorescent compound; andb) exposing said composition to actinic light having an emission wavelength between about 400 nm and 700 nm for a time sufficient to cause a change in color of the fluorescent compound. 2. The method according to claim 1, wherein said oral disease is selected from gingivitis, periodontitis, periodontal disease, oral thrush, lichen planus, stomatitis, herpes simplex lesion, oral mucositis, oral ulcers, oral submucous fibrosis, and glossitis. 3. The method according to claim 1, wherein said composition is exposed to actinic light for a period of less than about 5 minutes. 4. The method according to claim 1, wherein said composition is exposed to actinic light for a period of about 60 seconds to about 5 minutes. 5. The method according to claim 1, wherein said composition is exposed to actinic light for a period of less than about 5 minutes per cm2 of an area to be treated. 6. The method according to claim 1, wherein said composition is exposed to actinic light for a period of about 60 seconds to about 5 minutes per cm2 of an area to be treated. 7. The method according to claim 1, wherein said oral tissue comprises a gingiva or a portion thereof. 8. The method according to claim 1, wherein said oral tissue is on or near at least one tooth. 9. The method according to claim 8, wherein said oral tissue that is on or near at least one tooth is exposed to actinic light for a period of about at least 10 seconds on a vestibular side, and of about at least 10 seconds on a oral side. 10. The method according to claim 1, wherein the oxidant comprises about 1% to about 12% hydrogen peroxide. 11. The method according to claim 1, wherein the oxidant comprises about 3% to about 16% urea peroxide. 12. The method according to claim 1, wherein the composition further comprises at least one hydrophilic gelling agent. 13. The method according to claim 1, wherein the hydrophilic gelling agent is selected from glucose, modified starch, methyl cellulose, carboxymethyl cellulose, propyl cellulose, hydroxypropyl cellulose, carbomer polymers, alginic acid, sodium alginate, potassium alginate, ammonium alginate, calcium alginate, agar, carrageenan, locust bean gum, pectin, and gelatin. 14. The method according to claim 1, wherein the fluorescent compound is Eosin Y. 15. The method according to claim 1, wherein the fluorescent compound is selected from a xanthene derivative dye, an azo dye, a biological stain and a carotenoid. 16. The method according to claim 1, wherein the composition further comprises at least one of: rhodamine B, rhodamine WT, rhodamine G, phloxine B, rose bengal, merbromine, eosin B, fluorescein, erythrosine B, saffranin O, saffron red powder, annatto extract, brown algae extract, basic fuchsin, acid fuschin, 3,3′ dihexylocarbocyanine iodide, carminic acid, indocyanine green, crocetin, α-crocin (8,8-diapo-8,8-carotenoic acid), zeaxanthine, lycopene, α-carotene, β-carotene, bixin, fucoxanthine, methyl violet, neutral red, para red, amaranth, carmoisine, allura red AC, tartrazine, orange G, ponceau 4R, methyl red, murexide-ammonium purpurate, pyronine Y and pyronine B. 17. The method of claim 1, wherein the composition is applied prior to a supragingival debridement, a scaling/root planing, or both. 18. The method of claim 1, wherein the wound is exposed to the actinic light at least two, three, four, five or six times, and wherein a fresh application of the composition is applied before exposure to the actinic light. 19. The method of claim 1, wherein the composition further comprises a healing factor selected from glucosamine, allantoin and hyaluronic acid. 20. The method of claim 1, wherein the actinic light is emitted from a halogen lamp, an LED, or a plasma arc lamp.
