Abstract

A method of direct pulp capping of a tooth including administering a dental composition comprising betamethasone and gentamicin onto an exposed pulp of a tooth, and covering the dental composition present on the tooth with a glass ionomer cement. The dental composition is administered in an amount effective to form a calcification over the exposed pulp. A dental composition having betamethasone, gentamicin, and optionally including a Portland cement. The dental composition is administered to an exposed pulp of a tooth to form a calcification over the exposed pulp.

First claim

The invention claimed is:

1. A method of direct pulp capping of a tooth comprising:
administering a dental composition consisting of betamethasone, gentamicin, water, a paraffin, a liquid polyol, beeswax, a fatty alcohol, and a dispersing agent onto an exposed pulp of the tooth;
covering the dental composition present on the tooth with a glass ionomer cement; and
curing the glass ionomer cement to form a cured glass ionomer cement and to seal the dental composition in the region of the exposed pulp;
wherein the dental composition is administered in an amount effective to form a calcification over the exposed pulp.

2. The method of claim 1 , wherein the exposed pulp of the tooth is 2.5 mm-4 mm in occlusal depth, 3.5 mm-5 mm in mesiodistal width, and 2.5 mm-3.5 mm in faciolingual width.

3. The method of claim 1 , wherein the dental composition is in the form of a cream.

4. The method of claim 1 , wherein the calcification is a dentin bridge with a thickness of 2 μm-80 μm.

5. The method of claim 1 , wherein the glass ionomer cement is a self-curing glass ionomer cement or a resin-modified glass ionomer cement.

6. The method of claim 5 , wherein the self-curing glass ionomer cement or resin-modified glass ionomer cement is cured by light to seal the dental composition in the region of the exposed pulp.

7. The method of claim 1 , wherein the dental composition is administered onto the exposed pulp of the tooth forming a layer of the dental composition having a thickness of 0.3-7 mm.

8. The method of claim 1 , wherein the glass ionomer cement is a reaction product of a silicate glass powder and a poly(ethylene-co-methacrylic acid) ionomer.

9. The method of claim 8 , wherein a weight percent of the silicate glass powder in the glass ionomer cement is 25-35%, relative to a total weight of the glass ionomer cement.

10. The method of claim 1 , which forms a layered structure consisting of the tooth, a layer of the dental composition, and a layer of the cured glass ionomer cement, wherein the layer of the dental composition is disposed between the tooth and the layer of the cured glass ionomer cement.
