Abstract

Temporary dental cements used to temporarily affix a dental prosthesis or appliance to a tooth or other dental substrate includes one or more soothing agent to prevent or reduce tooth sensitivity. The temporary dental cement includes a mixture of an ion leaching agent, polycarboxylic acid, a soothing agent and water. The soothing agent (e.g., 2-ethoxybenzoic acid, phenol, a phenol derivative, such as 2-methoxy-4-methylphenol, or a “caine”-type anesthetic) is added in an amount so as to reduce or eliminate tooth sensitivity associated with the reaction between the polycarboxylic and the ion leaching agent (base). The temporary cement composition is sufficiently hydrophilic that it can be readily removed from the tooth when it is desired to permanently restore the tooth.

Claims

1. A multipart composition comprising at least two initially separate parts which, upon mixing the parts together, form a mixed temporary dental cement that is initially deformable and suitable for placement onto a person'"'"'s tooth and which hardens over time, the multipart composition comprising:

at least one polycarboxylic acid contained in at least one of the initially separate parts;

at least one ion leaching component contained in at least one other of the initially separate parts that does not contain the polycarboxylic acid;

at least one soothing agent contained in at least one of the initially separate parts in an amount so as to reduce tooth sensitivity caused by the mixed temporary dental cement compared to tooth sensitivity that would be caused by the dental cement in the absence of the soothing agent, with the proviso that the soothing agent is not potassium nitrate; and

optionally water contained in at least one of the initially separate parts.

2. A multi-part composition as defined in claim 1, the polycarboxylic acid comprising polyacrylic acid.

3. A multi-part composition as defined in claim 1, the ion leaching agent comprising at least one of a metal oxide or an aluminosilicate glass.

4. A multi-part composition as defined in claim 1, the soothing agent comprising at least one member selected from the group comprising phenol, phenol derivatives, 2-ethoxybenzoic acid, 2-methyl-4-methylphenol, eugenol, tall oil, rosin, pine gum, tetracaine, lidocaine, benzocaine, dyclonine, pramoxine, dibucaine, butacaine, cocaine, salts of the foregoing, analogues of the foregoing.

5. A multi-part composition as defined in claim 1, the soothing agent having a concentration of about 0.05% to about 25% by weight of the mixed temporary dental cement.

6. A multi-part composition as defined in claim 1, the soothing agent having a concentration of about 1% to about 20% by weight of the mixed temporary dental cement.

7. A multi-part composition as defined in claim 1, the soothing agent having a concentration of about 3% to about 15% by weight of the mixed temporary dental cement.

8. A multi-part composition as defined in claim 1, further comprising potassium nitrate within at least one of the initially separate parts to provide a desensitizing effect in addition to the soothing agent.

9. A multi-part composition as defined in claim 8, the potassium nitrate having a concentration of about 0.01% to about 20%.

10. A multi-part composition as defined in claim 1, further comprising at least one sugar or sugar derivative within at least one of the initially separate parts.

11. A multi-part composition as defined in claim 1, further comprising at least one thickening agent within at least one of the initially separate parts.

12. A multi-part composition as defined in claim 11, the thickening agent comprising at least one of fumed silica, fumed aluminum oxide, colloidal silica, or precipitated silica.

13. A multi-part composition as defined in claim 1, at least one of the initially separate parts having a color that differs from at least one other of the initially separate parts.

14. A dental repair system comprising:

a multi-barrel syringe; and

the multi-part composition of claim 1,

each initially separate part of the multi-part composition being contained in a corresponding syringe barrel of the syringe.

15. A kit for use in temporarily repairing a person'"'"'s tooth comprising:

at least one temporary dental prosthetic; and

the multi-part composition of claim 1.

16. A kit as defined in claim 15, further comprising at least one syringe into which at least one of the initially separate parts of the multi-part composition is loaded.

17. A kit as defined in claim 15, further comprising at least one applicator that may be used to apply the mixed temporary dental cement onto a tooth.

18. A kit as defined in claim 15, further comprising a topical anesthetic composition suitable for treating at least one of dental or gingival pain.

19. A multipart composition comprising at least two initially separate parts which, upon mixing the parts together, form a mixed temporary dental cement that is initially deformable and suitable for placement onto a person'"'"'s tooth and which hardens over time, the multipart composition comprising:

at least one polycarboxylic acid contained in at least one of the initially separate parts;

at least one ion leaching component contained in at least one other of the initially separate parts that does not contain the polycarboxylic acid;

at least one soothing agent contained in at least one of the initially separate parts in an amount so as to reduce tooth sensitivity caused by the mixed temporary dental cement compared to tooth sensitivity that would be caused by the dental cement in the absence of the soothing agent,

the soothing agent comprising at least one member selected from the group comprising phenol, phenol derivatives, 2-ethoxybenzoic acid, 2-methyl-4-methylphenol, eugenol, tall oil, rosin, pine gum, tetracaine, lidocaine, benzocaine, dyclonine, pramoxine, dibucaine, butacaine, cocaine, salts of the foregoing, analogues of the foregoing; and

optionally water contained in at least one of the initially separate parts.

20. A multipart composition comprising at least two initially separate parts which, upon mixing the parts together, form a mixed temporary dental cement that is initially deformable and suitable for placement onto a person'"'"'s tooth and which hardens over time, the multipart composition comprising:

at least one polycarboxylic acid contained in at least one of the initially separate parts;

at least one ion leaching component contained in at least one other of the initially separate parts that does not contain the polycarboxylic acid;

at least one soothing agent contained in at least one of the initially separate parts in an amount so as to reduce tooth sensitivity caused by the mixed temporary dental cement compared to tooth sensitivity that would be caused by the dental cement in the absence of the soothing agent,

the soothing agent comprising at least one of phenol, a phenol derivative, 2-ethoxybenzoic acid, 2-methyl-4-methylphenol, or eugenol; and

optionally water contained in at least one of the initially separate parts.
