Antioxidant compositions for treatment of inflammation or oxidative damage
One embodiment of the invention is directed to a method of preventing, reducing, or eliminating at least one negative effect of oxidative damage, such as an oral disease, caused by a dental device in the mouth of a patient. Another embodiment relates to a method of preventing, reducing, or eliminating at least one negative effect of inflammation. The method may include applying topically to a soft oral tissue in the patient an oral antioxidant composition. The antioxidant composition may include between 0.0001% and 5.0% w/w or at least one antioxidant, wherein the at least one antioxidant includes a natural phytochemcial antioxidant, a flavonoid, an anthocyanidin, a dihydrochalcone, a phenylpropanoid, a chalcone, a curcuminoid, a tannin, a stilbenoid, a coumarin, a carotenoid, or a vitamin, and an orally pharmaceutically acceptable carrier. The pH of the oral antioxidant composition may be at least 5.0.
1. A method of increasing viability of gingival fibroblasts that have suffered oxidative damage by a metal released from a dental device in the mouth of a patient comprising applying topically to a soft oral tissue in the patient an oral antioxidant composition comprising:
between 0.0001% and 5.0% total w/w of phloretin and ferulic acid and no additional antioxidants; and
an orally pharmaceutically acceptable carrier,
wherein the pH of the oral antioxidant composition is at least 5.0, and
wherein the antioxidant composition increases viability of gingival fibroblasts that have suffered oxidative damage by a metal released from a dental device in the mouth of the patient by exhibiting a synergistic effect.
2. The method of claim 1 , further comprising repeating the applying step after a selected time interval.
3. The method of claim 1 , further comprising reducing the number of reactive oxygen species in the mouth of the patient.
4. The method of claim 1 , further comprising repeating the applying step until the dental device is removed from the mouth of the patient.
5. The method of claim 1 , wherein the orally pharmaceutically acceptable carrier is one of a spray, liquid, gel, or paste.
6. The method of claim 1 , wherein the metal comprises at least one of zinc (Zn), copper (Cu), or nickel (Ni).
7. The method of claim 1 , wherein the dental device comprises a permanent or semi-permanent dental device.
8. The method of claim 1 , wherein the oral antioxidant composition remains in the mouth of the patient for at least five minutes.
9. The method of claim 1 , wherein the oral antioxidant composition further comprises an antibacterial composition.
10. The method of claim 9 , wherein the antibacterial composition comprises menthol.
11. The method of claim 9 , wherein the antibacterial composition comprises xylitol.
12. The method of claim 9 , wherein the antibacterial composition comprises thymol.
