Dental prophylaxis cup for mixing at least two media prior to dispensing
View Patent ↗Provided is prophylaxis cup for dentistry, comprising a first section storing a first medium, a second section storing a second medium, and one or more channels between the first section and the second section, wherein the first section, the second section and the one or more channels are adapted to allow the first medium and the second medium to be mixed, in response to a rotational movement of the prophylaxis cup. Provided also is a method for using prophylaxis cup in which the prophylaxis cup is positioned on a patient's tooth. A control is triggered to rotate the prophylaxis cup to cause a first medium stored in a first section of the prophylaxis cup to be mixed with a second medium stored in a second section of the prophylaxis cup. Provided further is a prophylaxis angle for dentistry, comprising a hand-piece, with the prophylaxis cup coupled to the hand-piece.
1. A prophylaxis cup for dentistry, comprising:
a first section storing a first medium;
a second section storing a second medium; and
one or more channels between the first section and the second section, wherein the first section, the second section and the one or more channels are adapted to allow the first medium and the second medium to be mixed, in response to a rotational movement of the prophylaxis cup, wherein the first and second mediums are each in the form of a paste or a liquid solution, one of the first and second mediums comprises a whitening agent, and the other of the first and second mediums comprises a catalyst that activates the whitening agent.
2. The prophylaxis cup of claim 1 , wherein:
the first medium is a dental paste comprising an abrasive agent and the whitening agent; and
the second medium is a liquid solution of the catalyst that activates the whitening agent.
3. The prophylaxis cup of claim 2 , wherein:
the first section is located peripheral to the second section;
the liquid solution of the catalyst has a lower viscosity than the dental paste; and
the rotational movement of the prophylaxis cup causes the liquid solution of the catalyst to move outwards to mix with at least one part of the dental paste, during a treatment of a patient's teeth.
4. The prophylaxis cup of claim 1 , wherein:
the first medium comprises a liquid solution of the whitening agent; and
the second medium comprises a dental paste comprising an abrasive agent and the catalyst.
5. The prophylaxis cup of claim 1 , wherein one or both of the first medium and the second medium comprise an abrasive agent.
6. The prophylaxis cup of claim 1 , wherein the first section is located on one open side of the prophylaxis cup and the second section is located on another open side of the prophylaxis cup.
7. The prophylaxis cup of claim 1 , further comprising:
additional sections storing the first medium.
8. The prophylaxis cup of claim 1 , wherein centrifugal forces generated by the rotational motion move the second medium stored in the second section via the one or more channels to the first section that stores the first medium.
9. The prophylaxis cup of claim 1 , wherein inner walls of the first section and the second section are flared outwards towards an end of the prophylaxis cup that is open and proximal to the patient's teeth to allow movement of at least the mixed first and second medium towards the patient's teeth.
10. The prophylaxis cup of claim 1 , wherein walls of the first and the second section have grooves or ridges to allow movement of at least the mixed first and second medium towards the patient's teeth.
11. The prophylaxis cup of claim 1 , wherein the prophylaxis cup is coupled to a hand-piece.
12. The prophylaxis cup of claim 1 , wherein the one or more channels are towards an end of the prophylaxis cup that is placed in contact with a patient's tooth to allow mixing of the first medium to the second medium immediately prior to application on the patient's tooth.
13. A prophylaxis angle for dentistry, comprising:
a hand-piece; and
a prophylaxis cup coupled to the hand-piece, wherein the prophylaxis cup comprises:
a first section storing a first medium;
a second section storing a second medium; and
one or more channels between the first section and the second section, wherein the first section, the second section and the one or more channels are adapted to allow the first medium and the second medium to be mixed, in response to a rotational movement of the prophylaxis cup, wherein the first and second mediums are each in the form of a paste or a liquid solution, one of the first and second mediums comprises a whitening agent, and the other of the first and second mediums comprises a catalyst that activates the whitening agent.
14. The prophylaxis angle of claim 13 , wherein:
the first medium is a dental paste comprising an abrasive agent and the whitening agent; and
the second medium is a liquid solution of the catalyst that activates the whitening agent.
15. The prophylaxis angle of claim 14 , wherein:
the first section is located peripheral to the second section;
the liquid solution of the catalyst has a lower viscosity than the dental paste; and
the rotational movement of the prophylaxis cup causes the liquid solution of the catalyst to move outwards to mix with the dental paste, during a treatment of a patient's teeth.
16. A method for using a prophylaxis cup, the method comprising:
positioning the prophylaxis cup on a patient's tooth; and
triggering a control to rotate the prophylaxis cup to cause a first medium stored in a first section of the prophylaxis cup to be mixed with a second medium stored in a second section of the prophylaxis cup, wherein the first and second mediums are each in the form of a paste or a liquid solution, one of the first and second mediums comprises a whitening agent, and the other of the first and second mediums comprises a catalyst that activates the whitening agent.
17. The method of claim 16 , wherein:
the first medium is a dental paste comprising an abrasive agent and the whitening agent; and
the second medium is a liquid solution of the catalyst that activates the whitening agent.
18. The method of claim 17 , wherein:
the first section is located peripheral to the second section;
the liquid solution of the catalyst has a lower viscosity than the dental paste; and
the rotational movement of the prophylaxis cup causes the liquid solution of the catalyst to move outwards via one or more channels to mix with the dental paste, during a treatment of a patient's teeth.
19. A prophylaxis cup for dentistry, comprising:
a first section storing a first flowable medium in the form of a paste or liquid solution;
a second section storing a second flowable medium in the form of a paste or liquid solution that is different than the first medium in both composition and viscosity; and
one or more channels between the first section and the second section, wherein the first section, the second section and the one or more channels allow one of the first or second flowable mediums to flow through the channel to be mixed with the other of the first or second flowable mediums, in response to a rotational movement of the prophylaxis cup.
20. The prophylaxis cup of claim 19 , wherein one of the first and second flowable mediums comprises a whitening agent, the other of the first and second flowable mediums comprises a catalyst that activates the whitening agent, and one or both of the first and second flowable mediums comprises an abrasive agent.
21. The prophylaxis cup of claim 19 , wherein:
the first section is located peripheral to the second section;
the second flowable medium has a lower viscosity than the first flowable medium; and
the rotational movement of the prophylaxis cup causes the second flowable medium to move outwards to mix with the first flowable medium, during a treatment of a patient's teeth.
22. The prophylaxis cup of claim 19 , wherein the first section is located on one open side of the prophylaxis cup and the second section is located on another open side of the prophylaxis cup.
