USE OF RHAMNOSE AND ARABINOSE FOR DENTAL POWDER JET CLEANING

Abstract

The invention relates to the use of a powder in a powder jet device for cleaning tooth surfaces by powder spraying, wherein the powder comprises rhamnose and/or arabinose. The invention also relates to a process for cleaning tooth surfaces with a powder jet device, wherein a powder comprising rhamnose and/or arabinose is used.

Claims

1. A powder for use in a powder jet device for cleaning tooth surfaces by powder spraying, the powder comprising rhamnose.

2. The powder according to claim 1, wherein the powder comprises >50 wt.-% rhamnose, based on the total weight of the powder.

3. The powder according to claim 1, wherein the powder comprises 60 to 99.5 wt.-% rhamnose, based on the total weight of the powder.

4. The powder according to claim 1, wherein the powder further comprises 0.5 to 2 wt.-% amorphous silicon dioxide.

5. The powder according to claim 1, wherein the maximum particle size of the powder is <200 pm.

6. The powder according to claim 1, wherein the maximum particle size of the powder is <120 pm.

7. The powder according to claim 1, wherein the average particle size of the powder is 5 to 40 pm.

8. The powder according to claim 1, wherein the powder further comprises glycine, sodium hydrogen carbonate and/or erythritol.

9. The powder according to claim 1, wherein the powder further comprises a bactericide, a bleaching agent and/or an analgesic.

10. (canceled)

11. (canceled)

12. The powder according to claim 1, wherein the powder or powder mixture comprises 60 to 99.5 wt.-% rhamnose, based on the total weight of the powder, 0.5 to 2 wt.-% amorphous silicon dioxide, based on the total weight of the powder, the maximum particle size (d.sub.100) of the powder is <120 pm and average particle size (d.sub.50) of the powder is 5 to 40 pm.

13. The powder according to claim 1, wherein the powder additionally comprises arabinose.

14. A process for cleaning tooth surfaces, comprising spraying a powder according to claim 1 with a powder jet device onto a tooth surface together with a gaseous or liquid carrier medium.

Description

[0037] FIG. 1 shows the cleaning efficiency [mm.sup.2/g] of arabinose and rhamnose compared to the commercially available cleaning powders PLUS from EMS (based on erythritol), COMFORT from EMS (based on sodium bicarbonate) and PERIO from EMS (based on glycine).

[0038] FIG. 2 shows the abrasiveness [μm/g] of the arabinose and rhamnose powders according to Examples 1 and 2 compared to the commercially available cleaning powders PLUS from EMS (based on erythritol) and COMFORT from EMS (based on sodium bicarbonate).

[0039] FIG. 3 shows the abrasiveness of rhamnose in comparison to the PLUS powder, tagatose and trehalose powders according to Example 3.

[0040] It has been demonstrated that the powders according to invention comprising rhamnose and arabinose have an improved abrasiveness as well as an improved cleaning efficiency compared to commercially available dental cleaning powders and compared to tagatose and trehalose.
