Antimicrobial denture
A denture containing a henna powder or a henna extract, each of which comes from pulverized henna leaves and may include any of lawsone, tannic acid, and 2-methoxy-1,4-napthoquinone and a denture fabrication material. A denture containing at least one first antimicrobial ingredient selected from the group consisting of henna powder or a henna extract, lawsone, tannic acid, and 2-methoxy-1,4-napthoquinone, and a second antimicrobial ingredient, and optionally, a biocompatible gel and an odor neutralizer.
1. A denture comprising:
a first antimicrobial ingredient, wherein the first antimicrobial ingredient is a henna powder or a henna extract, each of which comes from pulverized henna leaves and comprises at least one compound selected from the group consisting of lawsone, tannic acid, and 2-methoxy-1,4-napthoquinone;
a denture fabrication material; and
a biocompatible gel which is a hydrogel or a polymer gel that is a coating on the denture, integrated into the denture, or both;
wherein the first antimicrobial ingredient covers the surface of the denture fabrication material and extends into the interior of the denture fabrication material.
2. The denture of claim 1 , wherein the denture fabrication material comprises a cured acrylic resin which is poly(methyl methacrylate).
3. The denture of claim 1 , wherein the denture fabrication material comprises a cured acrylic resin which is poly(ethyl methacrylate), poly(butyl methacrylate), or mixtures thereof.
4. The denture of claim 1 , wherein the denture comprises 0.1% to 20% w/w of a total weight of the first antimicrobial ingredient relative to a total weight of the denture.
5. A denture, comprising
a first antimicrobial ingredient, wherein the first antimicrobial ingredient is a henna powder or a henna extract, each of which comes from pulverized henna leaves and comprises at least one compound selected from the group consisting of lawsone, tannic acid, and 2-methoxy-1,4-napthoquinone;
a denture fabrication material; and
an odor neutralizer comprising two or more aldehydes selected from the group consisting of 2-ethoxy benzylaldehyde, 2-isopropyl-5-methyl-2-hexenal, 5-methyl furfural, 5-methyl-thiophene-carboxaldehyde, adoxal, p-anisaldehyde, benzylaldehyde, bourgenal, cinnamic aldehyde, cymal, decyl aldehyde, floral super, florhydral, helional, lauric aldehyde, ligustral, lyral, melonal, o-anisaldehyde, pino acetaldehyde, bucinal, thiophene carboxaldehyde, trans-4-decenal, trans trans 2,4-nonadienal, and undecyl aldehyde;
wherein the first antimicrobial ingredient covers the surface of the denture fabrication material and extends into the interior of the denture fabrication material.
6. A denture comprising:
a first antimicrobial ingredient, wherein the first antimicrobial ingredient is a henna powder or a henna extract, each of which comes from pulverized henna leaves and comprises at least one compound selected from the group consisting of lawsone, tannic acid, and 2-methoxy-1,4-napthoquinone;
a second antimicrobial ingredient;
a denture fabrication material; and
a biocompatible gel which is a hydrogel or a polymer gel that is a coating on the denture, integrated into the denture, or both;
wherein the first antimicrobial ingredient, the second antimicrobial ingredient, or both coat the surface of the denture fabrication material and extend into the interior of the denture fabrication material.
7. The denture of claim 6 , wherein the second antimicrobial ingredient is a silver nanoparticle, a titanium dioxide particle, a silicon compound or an essential oil.
8. The denture of claim 7 , wherein the second antimicrobial ingredient is the silver nanoparticle, and the silver nanoparticle has an average diameter of 40 nm to 80 nm.
9. The denture of claim 7 , wherein the second antimicrobial ingredient is the titanium dioxide particle, and the titanium dioxide particle has an average diameter of 40 nm to 160 nm.
10. The denture of claim 7 , wherein the second antimicrobial ingredient is the essential oil, and the essential oil is at least one selected from the group consisting of lemongrass oil, peppermint oil, neem oil, orange oil, palmarosa oil, and patchouli oil.
11. The denture of claim 6 , wherein the denture comprises 0.1% to 25% w/w of a total weight of the first antimicrobial ingredient and the second antimicrobial ingredient relative to a total weight of the denture.
12. The denture of claim 6 , further comprising a third antimicrobial ingredient selected from the group consisting of 3-alkyl-2-hydroxy-1,4-napthoquinone, 2-amino-1,4-napthoquinone, and 3-aminophenyl-2-hydroxy-1,4-napthoquinone.
13. The denture of claim 12 , wherein the denture comprises 0.1%-5% w/w of the third antimicrobial ingredient relative to a total weight of the denture.
14. The denture of claim 6 , further comprising an odor neutralizer comprising two or more aldehydes selected from the group consisting of 2-ethoxy benzylaldehyde, 2-isopropyl-5-methyl-2-hexenal, 5-methyl furfural, 5-methyl-thiophene-carboxaldehyde, adoxal, p-anisaldehyde, benzylaldehyde, bourgenal, cinnamic aldehyde, cymal, decyl aldehyde, floral super, florhydral, helional, lauric aldehyde, ligustral, lyral, melonal, o-anisaldehyde, pino acetaldehyde, bucinal, thiophene carboxaldehyde, trans-4-decenal, trans trans 2,4-nonadienal, and undecyl aldehyde.
15. The denture of claim 6 , wherein the denture fabrication material comprises a cured acrylic resin which is poly(methyl methacrylate).
