8. The device of claim 1, further comprising a reader for reading a container data carrier which is associated with said container and storing information associated with said dental material(s).

9. The device of claim 1, further comprising a reader for reading a data carrier associated with said at least one information device.

10. The device of claim 8, said data carrier being an RFID tag.

30. System comprising a dental material processing device according to claim 1 and at least one information device according to claim 11.

11. Information device for use in processing dental material(s) with a dental material processing device, wherein the information device provides time information related to dental procedures to the user, and is separable from said dental material processing device, the information device comprising:

a receiver for communication with said dental material processing device for receiving data signals associated with said dental material(s) to be processed; and

an indicator for indicating visual and/or aural information to a user based on said data.

12. The information device of claim 11, wherein said at least one information device is further separable from a container comprising said dental material(s).

13. The information device of claim 11, wherein the information device is independent from said dental material processing device.

14. The information device of claim 11, wherein said data associated with said dental material(s) includes at least one of:

the name of the material(s), working time of the material(s), setting time of the material(s).

15. The information device of claim 11, further comprising a timer.

16. The information device of claim 15, said timer adapted to initiate the measurement of a period of time by a command signal received from said dental material processing device.

17. The information device of claim 16, said timer being adapted to be initiated by a command signal input by a user.

18. The information device of claim 16, said indicator indicating the remaining time provided by said timer.

19. The information device of claim 16, said command signal initiating a first timer function in the information device with respect to the working time for the dispensed material.

20. The information device of claim 16, said command signal initiating a second timer function in the information device with respect to the setting time for the dispensed material.

21. The information device of claim 20, said second timer function being initiated subsequent to expiry of the working time measured by said first timer function.

22. The information device of claim 16, further comprising a notification for outputting a signal when a time period has elapsed.

23. The information device of claim 22, said notification being a visual and/or aural notification.

24. The information device of claim 11, further comprising a data carrier including the identity of said information device.

25. The information device of claim 24, said data carrier being adapted for contactless read-out.

26. The information device of claim 25, said data carrier being an RFID tag.

27. The information device of claim 11, further comprising memory for storing said data.

28. The information device of claim 11, said indicator being a visual and/or aural indicator.

29. The information device of claim 28, said visual indicator comprising a display and/or a light emitting device.

31. Method of communication between a dental material processing device for processing dental material(s) and at least one separable information device, which method comprises:

(a) said dental material processing device transmitting an information signal identifying said at least one information device to be contacted for activating said at least one information device.

32. The method of claim 31, further comprising the step:

(b) said dental material processing device further transmitting specific data associated with said dental material(s) to said at least one information device.

33. The method of claim 31, said information signal further identifying said dental material device.

34. The method of claim 32, wherein said at least one information device sends a response signal to said dental material processing device upon receipt of said information signal.

35. The method of claim 34, wherein step (b) is initiated upon receipt of said response signal at said dental material processing device.

36. The method of claim 34, wherein step (b) is repeated after change of the dental material(s) in said dental material processing device.

37. The method of claim 31, wherein said data associated with said dental material(s) includes at least one of the name of the material(s), working time of the material(s), setting time of the material(s).

38. The method of claim 31, wherein step (a) is preceded by the step of said dental material processing device sending an interrogation signal in order to detect the presence of an information device.

39. The method of claim 38, further comprising the step of obtaining the identity of the detected information device.
