1. A motorized toothbrush comprising:
- a head carrying cleaning elements on an upper surface thereof;
a handle configured to connect to a power source;
a neck extending between the head and the handle;
at least one pair of electrical conducting elements including an anode and a cathode, the anode and the cathode being disposed in respective bores spaced from each other in a lower surface of the neck facing away from the upper surface of the head, a portion of the anode and a portion of the cathode exposed to an exterior environment of the toothbrush; and
a motorized device;
wherein the motorized device is activated upon contact of the anode and the cathode to an electrolyte solution, the electrolyte solution extending between the cathode and the anode.

Abstract
An oral care instrument, such as a motorized toothbrush, which activates upon exposure to the oral environment of the user, is described. The electrical conductivity of saliva, optionally mixed with toothpaste and water, may be utilized to complete an electrical circuit that powers a motorized device within the instrument.

20. A motorized toothbrush comprising:
-
a head carrying cleaning elements on an upper surface thereof; a handle; a neck extending between the head and the handle; a power source contained within the handle; a motorized device operably connected to the power source and operably connected to the head; electrical conducting elements comprising an anode and a cathode operably connected to the power source and the motorized device, the anode and the cathode disposed in respective bores spaced from each other in a lower surface of the neck facing away from the upper surface of the head, a portion of the anode and a portion of the cathode exposed to an exterior environment of the toothbrush; and a switch operably connected to at least one of the electrical conducting elements and the power source; wherein the motorized device is activated upon contact of the anode and the cathode to an electrolyte solution having a threshold conductivity, the electrolyte solution extending between the cathode and the anode.
