Abstract
Official abstract text for this publication.
The present disclosure relates to a combination, a composite staining kit and a method for revealing a composite material on a tooth.
First claim
Opening claim text (preview).
1 . A method of revealing a composite material comprising: a. applying a phenolic residue-containing compound to the composite material; and b. applying a staining agent after step a. 2 . The method of claim 1 , wherein said step of applying the phenolic residue-containing compound is comprising applying a solution of said phenolic residue-containing compound to the composite material and drying said solution of said phenolic residue-containing compound before applying the staining agent. 3 . The method of claim 1 , wherein said step of applying the staining agent is comprising applying a solution of said staining agent and drying said solution of said staining agent. 4 . The method of claim 1 , wherein said step of applying the phenolic residue-containing compound is comprising applying a solution of said phenolic residue-containing compound to the composite material, drying said solution of said phenolic residue-containing compound, washing said composite material with water and drying said washed composite material before applying the staining agent and wherein said step of applying the staining agent is comprising applying a solution of said staining agent, drying said solution of said staining agent, washing said composite material with water and drying said washed composite material. 5 . The method of claim 1 , wherein said the phenolic residue-containing compound is a mono-aromatic, topically non-toxic compound. 6 . The method of claim 1 , wherein said phenolic residue-containing compound is a mono-aromatic, orally non-toxic compound in a form of an ethanolic solution, the compound being non-toxic for natural tooth and having one or more of the following properties: substantially soluble in ethanol at room temperature, a MW of from about 90 to 220, and a Log P of from about 1.4 to about 5.3. 7 . The method of claim 1 , wherein said phenolic residue-containing compound is methyl salicylate, thymol or phenol. 8 . The method of claim 1 , wherein said staining agent is a food-grade dye. 9 . The method of claim 1 , wherein said staining agent is methylene blue, Brilliant Blue FCF or Phloxine B. 10 . The method of claim 1 , wherein said composite material is a dental filling composite material or an orthodontic bonding resin for brackets. 11 . A composite staining kit comprising i) a phenolic residue-containing compound and ii) a staining agent wherein each of i) and ii) are in separate packaging or formulation. 12 . The composite staining kit of claim 11 , wherein said phenolic residue-containing compound is an orally non-toxic compound for the mouth of a patient, and non-toxic for natural tooth and wherein said staining agent is a food-grade dye. 13 . The composite staining kit of claim 11 , wherein said phenolic residue-containing compound is methyl salicylate, thymol or phenol. 14 . The composite staining kit of claim 11 , wherein said staining agent is methylene blue, Brilliant Blue FCF or Phloxine B. 15 . The composite staining kit of claim 11 , wherein said composite material is a dental filling composite material or an orthodontic bonding resin for brackets. 16 . A combination comprising i) a phenolic residue-containing compound and ii) a staining agent. 17 . The combination of claim 16 , wherein said the phenolic residue-containing compound is a mono-aromatic, topically non-toxic compound. 18 . The combination of claim 16 , wherein said phenolic residue-containing compound is methyl salicylate, thymol or phenol. 19 . The combination of claim 16 , wherein said staining agent is a food-grade dye. 20 . The combination of claim 16 , wherein said staining agent is methylene blue, Brilliant Blue FCF or Phloxine B.
