It contains eugenol, isoeugenol, methyl-eugenol or an isomer thereof. A method for removing orthodontic fixtures adhered with a dental cement or resin to the enamel surfaces of teeth from these surfaces by contacting the dental cement or resin with a composition containing eugenol. ## Claims ### Claim 1 A composition having a pH ranging from 6.0 to 8.0 comprising: eugenol, at least one crosslinked polymer of acrylic acid or other gelling agent, and at least one polysorbate in an amount of 25-50 wt % of the total weight of the composition; wherein said composition contains an amount of eugenol sufficient to reduce the Vickers hardness of a cured or hardened orthodontic bonding adhesive cement or resin to a value of 70 or less after contact for at least 10 mins and/or is sufficient to reduce debonding force needed to remove a metal bracket from an enamel surface of a tooth compared to debonding force needed to remove a metal bracket not contacted with the composition. ### Claim 2 (depends on 1) The composition of claim 1 that comprises eugenol in an amount ranging from 0.5 to 10 wt %, relative to a total weight of the composition. ### Claim 3 (depends on 1) The composition of claim 1 that comprises 0.5 to 10 wt % of one or more crosslinked polymers of acrylic acid or Carbopol 934 or 940 as a gelling agent. ### Claim 4 (depends on 1) The composition of claim 1 that comprises 0.5 to 10 wt % of at least one gelling agent selected from the group consisting of hydroxy propyl methy cellulose, polaxamer, and carboxy methyl cellulose sodium. ### Claim 5 (depends on 1) The composition of claim 1 that comprises 1 to 40 wt % at least one polysorbate. ### Claim 6 (depends on 1) The composition of claim 1 that further comprises 2 to 30 wt % of at least one of polyethylene glycol, propylene glycol, or glycerol as a cosurfactant. ### Claim 7 (depends on 1) The composition of claim 1 that further comprises 0.01 to 0.45 wt % of at least one of methyl-paraben, propy-1-paraben, or butyl-paraben as a preservative. ### Claim 8 (depends on 1) The composition of claim 1 that comprises 5-15 wt % clove oil, 20-30 wt % polysorbate 20 (TWEEN 20®), 10-15 wt % propylene glycol, 1-3 wt % crosslinked polyacrylate polymer, and water. ### Claim 9 (depends on 1) The composition of claim 1 that has a viscosity ranging from 1,000 to 5,000 cP. ### Claim 10 (depends on 1) The composition of claim 1 that has a viscosity of more than 5,000 cP. ### Claim 11 (depends on 1) The composition of claim 1, comprising the at least one polysorbate in an amount of 25-40 wt % of the total weight of the composition. ### Claim 12 (depends on 1) The composition of claim 1, comprising the eugenol in an amount of 10-25 wt % of the total weight of the composition. ### Claim 13 (depends on 1) The composition of claim 1, comprising the eugenol in an amount of 12.5-25 wt % of the total weight of the composition. ### Claim 14 (depends on 1) The composition of claim 1, comprising the eugenol in an amount of 7-20 wt %, the polysorbate in an amount of 25-40 wt %, a crosslinked polyacrylate polymer in an amount of 1-3 wt %, a polypropylene glycol in an amount of 10-30 wt % of the total weight of the composition, and water. ### Claim 15 (depends on 1) The composition of claim 1, further comprising: one or more other nonionic surfactants in an total amount of nonionic surfactant and polysorbate of 30-50 wt % of the total weight of the composition. ### Claim 16 (depends on 1) A kit, comprising: the composition of claim 1, a tray suitable for retaining the composition and contacting the composition with at least one dental bracket or other dental fixture bonded with a dental cement or resin to teeth, and, one or more of packaging materials and instructions for use. ### Claim 17 (depends on 16) The kit of claim 16, wherein the tray is customized or cast to fit over a subject's teeth that are bonded to brackets or other dental fixtures. ### Claim 18 A composition having a pH ranging from 6.0 to 8.0 comprising: eugenol, at least one crosslinked polymer of acrylic acid or other gelling agent, and at least one polysorbate in an amount of 22-50 wt % of the total weight of the composition; wherein said composition contains an amount of eugenol sufficient to reduce the Vickers hardness of a cured or hardened orthodontic bonding adhesive cement or resin to a value of 70 or less after contact for at least 10 mins and/or is sufficient to reduce debonding force needed to remove a metal bracket from an enamel surface of a tooth compared to debonding force needed to remove a metal bracket not contacted with the composition. ### Claim 19 (depends on 18) The composition of claim 18, further comprising: at least one co-surfactant in an amount of 2-20 wt %.
