Abstract

A substance that sets in a relatively short time for use in general dentistry and in endodontics to replace natural tooth material, the substance comprising untreated mineral trioxide aggregate and milled mineral trioxide aggregate, or comprising untreated mineral trioxide aggregate, milled mineral trioxide aggregate and water. A method of making a substance that sets in a relatively short time for use in general dentistry and in endodontics to replace natural tooth material, the method comprising milling by high shear and impact impingement of particles using high pressure homogenization. A method for use in general dentistry and in endodontics to replace natural tooth material.

First claim

What is claimed is:

1. A substance for use in general dentistry and in endodontics to replace natural tooth material, the substance comprising:
untreated mineral trioxide aggregate comprising particles with a median maximum particle diameter; and
reduced particle size mineral trioxide aggregate comprising particles of mineral trioxide aggregate subjected to high shear homogenization,
wherein the reduced particle size mineral trioxide aggregate has a reduced median maximum particle diameter compared to the particles of the untreated mineral trioxide aggregate,
wherein the untreated mineral trioxide aggregate and reduced particle size mineral trioxide aggregate together are total mineral trioxide aggregate.

2. The substance of claim 1 , further comprising a liquid selected from the group consisting of a local anesthetic and water.

3. The substance of claim 1 , where the untreated mineral trioxide aggregate comprises a median maximum particle diameter size of between five and thirty times larger than the median maximum particle diameter size of the reduced particle size mineral trioxide aggregate.

4. The substance of claim 1 , where the untreated mineral trioxide aggregate comprises a median maximum particle diameter size of between five and fifteen times larger than the median maximum particle diameter size of the reduced particle size mineral trioxide aggregate.

5. The substance of claim 1 , where the untreated mineral trioxide aggregate comprises a median maximum particle diameter size of between eight and twelve times larger than the median maximum particle diameter size of the reduced particle size mineral trioxide aggregate.

6. The substance of claim 1 , comprising between 1% and 99.9% untreated mineral trioxide aggregate and between 0.1% and 99% reduced particle size mineral trioxide aggregate.

7. The substance of claim 1 , comprising between 25% and 99.5% untreated mineral trioxide aggregate and between 0.5% and 75% reduced particle size mineral trioxide aggregate.

8. The substance of claim 1 , comprising between 40% and 99% untreated mineral trioxide aggregate and between 1% and 60% reduced particle size mineral trioxide aggregate.

9. The substance of claim 1 , comprising between 45% and 75% untreated mineral trioxide aggregate and between 25% and 55% reduced particle size mineral trioxide aggregate.

10. The substance of claim 1 , comprising 75% untreated mineral trioxide aggregate and 25% reduced particle size mineral trioxide aggregate.

11. The substance of claim 1 , comprising 50% untreated mineral trioxide aggregate and 50% reduced particle size mineral trioxide aggregate.

12. The substance of claim 2 , comprising between 50% and 95% total mineral trioxide aggregate and between 5% and 50% water, where the total mineral trioxide aggregate comprises between 1% and 99.9% untreated mineral trioxide aggregate and between 0.1% and 99% reduced particle size mineral trioxide aggregate.

13. The substance of claim 2 , comprising between 50% and 95% total mineral trioxide aggregate and between 5% and 50% water, where the total mineral trioxide aggregate comprises between 25% and 99.5% untreated mineral trioxide aggregate and between 0.5% and 75% reduced particle size mineral trioxide are ate.
