Abstract

Disclosed are systems, methods, compositions and kits for mineralizing tissue, particularly dental tissue. The methods, compositions and kits may be used to strengthen and prevent weakening of the tissue. For example, the methods, compositions and kits may be used for treating and filling cavities in teeth caused by tooth decay.

Claims (11)

1. A remineralizing restorative composition for producing a mineralized dental tissue, the remineralizing restorative composition comprising:

a calcium ion source and a hydroxide ion source, wherein the calcium ion source and the hydroxide ion source is a cement;

a calcium phosphate-binding apatite stabilizer and a collagen-binding nucleation factor as a single biomimetic entity wherein the single biomimetic entity comprises poly(acrylic acid-co-vinyl phosphonic acid), poly(aspartic acid-co-vinyl phosphonic acid), poly(methacrylic acid-co-vinyl phosphonic acid), poly(acrylic acid-co-vinyl aminomethylene phosphonic acid), poly[acrylic acid-co-bis(2-chloroethyl)vinylphosphonate], poly[acrylic acid-co-1-hydroxyethylidene-1,1-diphosphonic acid] or poly[aspartic acid-co-bis(2-chloroethyl) vinylphosphonate;

a phosphate ion source; and

wherein the calcium ions are released over time for at least 30 days.

2. The composition of claim 1 , wherein the remineralizing restorative material comprises a resin.

3. The composition of claim 1 , formulated as a gel or paste.

4. A kit comprising:

a remineralizing restorative composition for producing a mineralized dental tissue comprising: (a) a calcium ion source and a hydroxide ion source, wherein the calcium ion source and the hydroxide ion source is a cement; (b) a phosphate ion source; and (c) a calcium phosphate-binding apatite stabilizer and a collagen-binding nucleation factor as a single biomimetic entity wherein the single biomimetic entity comprises poly(acrylic acid-co-vinyl phosphonic acid), poly(aspartic acid-co-vinyl phosphonic acid), poly(methacrylic acid-co-vinyl phosphonic acid), poly(acrylic acid-co-vinyl aminomethylene phosphonic acid), poly[acrylic acid-co-bis(2-chloroethyl)vinylphosphonate], poly[acrylic acid-co-1-hydroxyethylidene-1,1-diphosphonic acid] or poly[aspartic acid-co-bis(2-chloroethyl) vinylphosphonate; wherein the remineralizing restorative composition is provided in a sealed container with an opening suitable for delivery of the remineralizing restorative composition to the site of mineralization, wherein the calcium ions are released over time for at least 30 days; and

instructions for use.

5. The kit of claim 4 , wherein the remineralizing restorative material comprises a resin.
