Abstract

A dental device comprising: a handle and; a stem. The stem having a tip with an end. The tip has a first groove winding therearound extending from a first distal point proximate the end towards the handle at least one complete turn around the tip to a first-groove termination point. The stem has a first flange projecting outward therefrom and winding therearound. The first flange extends away from the handle from a first proximal point towards the end of the tip to a first-flange termination point. At least a portion of the stem having the first groove and at least a portion of the first flange is suitable for insertion into an area between two teeth, whereby the area between the teeth may be cleaned by the at least a portion of the stem inserted between the teeth.

Claims (31)

1. A dental device comprising

a handle;

a stem,

the stem having a tip with an end, the tip having a first groove winding therearound extending from a first distal point proximate the end towards the handle at least one complete turn around the tip to a first-groove termination point,

the stem having a first flange projecting radially outwardly therefrom and winding therearound, the first flange extending away from the handle from a first proximal point towards the end of the tip to a first-flange termination point, the first flange having a stepwise configuration formed by a series of planar step portions interconnected by a series of curved portions,

at least a portion of the stem having the first groove and at least a portion of the first flange being suitable for insertion into an area between two teeth;

whereby the area between the teeth may be cleaned by the at least a portion of the stem inserted between the teeth.

2. The dental device of clam 1 , wherein the first-groove termination point and the first-flange termination point are axially offset from one another.

3. The dental device of claim 2 , wherein the first-groove termination point is closer to the end of the tip than is the first flange termination point.

4. The dental device of claim 3 , wherein the first-groove termination point is further from the end of the tip than is the first-flange termination point.

5. The dental device of claim 1 , wherein the first groove is continuous with a valley formed between successive turns of the first flange.

6. The dental device of claim 1 , wherein the first groove and the first flange are of an opposite handedness.

7. The dental device of claim 1 , wherein the first groove has a series of linear portions interconnected by a series of curved portions.

8. The dental device of claim 7 , wherein corresponding linear portions of each turn of the first groove are parallel.

9. The dental device of claim 8 , wherein each turn of the first groove has four distinct linear portions.

10. The dental device of claim 1 , wherein the first groove is discontinuous.

11. The dental device of claim 1 , wherein the first flange is discontinuous.

12. The dental device of claim 1 , further comprising at least one channel extending longitudinally along an exterior surface of the stem at least in part through discontinuities in at least one of the first flange and the first groove.

13. The dental device of claim 12 , wherein the stem has at least one opening.

14. The dental device of claim 1 , wherein at least a portion of the stem is at least one of coated and impregnated with a dentally-active material.

15. The dental device of claim 1 , further comprising a plurality of bristles extending outwardly from radially around the stem towards the end of the tip.

16. The dental device of claim 15 , wherein an even outer dentally-active edge is formed by the bristles.

17. The dental device of claim 15 , wherein an outwardly sloping outer dentally-active edge is formed by the bristles.

18. The dental device of claim 15 , wherein an inwardly sloping outer dentally-active edge is formed by the bristles.

19. The dental device of claim 1 , further comprising a dome-shaped cup extending outwardly from radially around the stem towards the tip.

20. The dental device of claim 1 , wherein corresponding planar step portions of each turn of the first flange are parallel.

21. The dental device of claim 20 , wherein each turn of the first flange has four distinct planar step portions.

22. The dental device of claim 1 , wherein the first flange is a right-handed winding.

23. The dental device of claim 1 , wherein the first flange is a left-handed winding.

24. The dental device of claim 1 , wherein the first-groove termination point and the first-flange termination point are a same point, whereby the first groove is continuous with the first flange.

25. The dental device of claim 1 , wherein the first groove and the first flange are of a same handedness.
