Problems solved by technology

It is difficult for the clinician to tell when the paste is fully mixed
Additionally, during the cleaning steps after the cement has been applied to the tooth or other tooth structure, it can be difficult to discern the location of excess material that needs to be removed, especially since the material is designed to blend into the tooth color or match the tooth structure. color
Another problem with adhesive is that it is difficult to see where the adhesive is placed
Commercially available products do not adequately address these issues

Embodiment 1

[0047] Paste A1 was mixed with paste B3 in a ratio of 1:1. Mixing was accomplished by centrifugation at approximately 3000 RPM (revolutions per minute) for 15 seconds. The mixed paste has a dark purple color. This paste was placed in a metal mold having a thickness of 1 mm and a diameter of 20 mm. The mixture cured to a hard disk within 10 minutes. The color of the paste at this point was dark purple. After 1 day in water at 37°C, the purple color became significantly lighter, and after 3 days in water at 37°C, the purple color almost disappeared (very light purple). Color was measured as quickly as possible (10 minutes, 1 hour, 1 day and 3 days) using the L, a and b systems and the results are listed in Table 3.

Embodiment 2

[0051] Paste A2 was mixed with paste B3 in a ratio of 1:1. Mixing was accomplished by centrifugation at approximately 3000 RPM (revolutions per minute) for 15 seconds. The mixed paste has a dark purple color. This paste was placed in a metal mold having a thickness of 1 mm and a diameter of 20 mm. The mixture cured to a hard disk within 10 minutes. At this point, the paste was dark purple in color. After 1 day in water at 37°C, the purple color became significantly lighter, and after 3 days in water at 37°C, the purple color almost disappeared. Color was measured as quickly as possible (10 minutes, 1 hour, 1 day and 3 days) using the L, a and b systems and the results are listed in Table 4.

Embodiment 3

[0055] Paste A3 was mixed with paste B1 in a ratio of 1:1. Mixing was accomplished by centrifugation at approximately 3000 RPM (revolutions per minute) for 15 seconds. The mixed paste has a dark purple color. This paste was placed in a metal mold having a thickness of 1 mm and a diameter of 20 mm. The mixture cured to a hard disk within ten minutes. At this point, the paste was dark purple in color. After 1 day in water at 37°C, the purple color became significantly lighter, and after 3 days in water at 37°C, the purple color almost disappeared (very light purple). Color was measured as quickly as possible (10 minutes, 1 hour, 1 day and 3 days) using the L, a and b systems and the results are listed in Table 5.

Abstract

A dental material is provided that exhibits a color change upon or after mixing or contacting components of the composition. The composition includes an acidic component in one part, and a basic component in another part that upon contact with the acidic component initiates a chemical reaction thereof that alters the pH of the composition. An acid or base sensitive color change agent is present in the composition that registers the change in pH by changing color as the pH changes.

Description

[0001] Related Application Cross Reference [0002] Pursuant to 37 C.F.R. §1.78(a)(4), this application claims previously co-pending Provisional Application No. 61 / 410,171, filed November 4, 2010, and previously co-pending The benefit and priority of Provisional Application Nos. 61 / 410,443 and 61 / 410,565 of , which are specifically incorporated herein by reference. field of invention [0003] The present invention relates to dental materials and, in certain embodiments, to dental cements and adhesives. Background of the invention [0004] Hand mixing is widely used for dental materials, eg for the current dental cement pastes, and mixing efficiency is always of concern. It is difficult for the clinician to tell when the paste is completely mixed. Additionally, during the cleaning steps after the cement has been applied to the tooth or other tooth structure, it can be difficult to discern the location of excess material that needs to be removed, especially since the materia...
