Abstract

A novel dental device is disclosed for facilitating oral hygiene. The device includes a light source and a light guide, where light from the light source is propagated through the light guide so that it refracts from the end thereof. Through this refraction it at least partially illuminates bristles, or dental floss or a dental pick and in use illuminates, at least partially, teeth and gums within the mouth. Preferably the dental device utilizes a light source of such a wavelength that facilitates killing of bacteria.

Claims

1. A dental device comprising:

a body comprising a handle and a head for being at least partially inserted into a mouth;

a light source for emitting light of at least a wavelength and disposed within the body opposite the head;

a light guide having a first end optically coupled with the light source and a second end disposed proximate the head, wherein the second end of the light guide is for refracting at least a portion of the light emitted from the light source into the air for illuminating at least a portion of an inside of the mouth;

a control circuit coupled with the light source; and

,

a battery compartment coupled with the control circuit.

2. A dental device according to claim 1, wherein the light guide comprises a third end disposed proximate the head and optically coupled with the light source wherein the third end of the light guide is for refracting at least a portion of the light emitted from the light source into a gap formed between the second and third ends.

3. A dental device according to claim 2 wherein the gap is an air gap.

4. A dental device according to claim 1 wherein the head comprises a first arm disposed opposite a second arm forming a gap between the arms and where the second end of the light guide is for refracting at least a portion of the light emitted from the light source into the gap.

5. A dental device according to claim 4 wherein the first arm comprises a first groove and the second arm comprises a second groove for having dental floss disposed within these grooves for spanning the gap wherein the light from the light source that refracts from the second end at least partially illuminates the dental floss.

6. A dental device according to claim 1 wherein the head comprises bristles disposed proximate the second end of the light guide wherein the light from the light source that refracts from the second end at least partially illuminates the bristles.

7. A dental device according to claim 1 comprising a vibrating motor coupled with the control circuit for vibrating of the head.

8. A dental device according to claim 1 comprising:

a capacitive sensor plate coupled with the control circuit and disposed in the head in proximity of the second end of the light guide for coupling to the control circuit, the capacitive sensor plate for sensing at lease one of a presence of a capacitance proximate the second and an absence of a capacitance proximate the second end and for operating the light source in dependence thereon.

9. A dental device according to claim 1 wherein the light source is at least one of a laser light source and a LED light source.

12. A dental device according to claim 1 comprising a releasable coupling between the head and the handle wherein the second end of the light guide is releasably coupled with the first end of the light guide for facilitating removing the head from the handle.

13. A dental device according to claim 1 wherein the at least a wavelength of the light source is within a wavelength range that facilitates killing of bacteria.

15. A method according to claim 13 comprising releasably coupling of the head with the handle.

16. A method according to claim 13 comprising:

providing at least one of bristles and dental floss and a dental pick disposed proximate the head, wherein refracting comprises illuminating at least a portion of the at least one of bristles and dental floss and a dental pick.

17. A method according to claim 13 comprising:

sensing a capacitance proximate the head and illuminating the light source in dependence upon a presence of the capacitance.

10. A dental device according to claim 10 wherein the at least a wavelength of the light source is at least within an infrared and ultraviolet spectrum.

11. A dental device according to claim comprising:

a removeable dental pick that is removeably coupled with the head and disposed proximate the second end of the light guide for being at least partially illuminated by light refracting from the second end of the light guide.

14. A method comprising:

providing a dental device body;

providing handle as part of the body;

providing a head as part of the body opposite the handle;

providing a light source disposed in the handle;

providing a light guide optically coupled with the light source at a first end;

providing at least a surface for refraction of the light guide at a second end, which is opposite the first end;

propagating light from the light source through the light guide; and

refracting light from the at least a surface for refraction proximate the head.

18. A dental device comprising:

a body comprising a handle and a head, where the head is disposed opposite the handle;

a light source for emitting light of at least a wavelength and disposed within the body opposite the head;

at least one of bristles and dental floss and a dental pick disposed proximate the head;

a light guide having a first end optically coupled with the light source and a second end disposed proximate the head, wherein the second end of the light guide is for refracting at least a portion of the light emitted from the light source into the air for illuminating at least one of bristles and dental floss and a dental pick;

a control circuit coupled with the light source; and

,

a battery compartment coupled with the control circuit.

19. A dental device according to claim 18 comprising:

a capacitive sensor plate coupled with the control circuit and disposed in the head in proximity of the second end of the light guide for coupling to the control circuit, the capacitive sensor plate for sensing at lease one of a presence of a capacitance proximate the second and an absence of a capacitance proximate the second end and for operating the light source in dependence thereon.

20. A dental device according to claim 18 comprising a releasable coupling between the head and the handle wherein the second end of the light guide is releasably coupled with the first end of the light guide for facilitating removing the head from the handle.
