摘要:
The toothbrush includes a handle portion (12 or 55) and a brushhead portion (14 or 57) with a bristle set (20 or 53) at one end of the brushhead. At least one sensor (16 or 56 is located either on the handle of the toothbrush or on the bristle set back plate (54) of the toothbrush. When the sensor is located on the handle of the toothbrush, the position of the brushhead is determined by a processor (44 or 58) relative to the inside or outside surfaces of the teeth on the basis of the temperature detected by the sensor, either the outside environmental temperature or the skin temperature of the user. When the sensor is located on the bristle set back plate, the determination is made on the basis of the position of the bristle set relative to the cheek of the user.

An oral care system is disclosed. The oral care system includes an electric toothbrush having an energy source; an electronic circuit including a microcontroller and one or more electric loads; and at least one sensor for providing a signal indicating a relevant change of an external condition; and a mobile computing device that stores a computer application. In response to a relevant change in an external condition, the signal has an energy content allowing the microcontroller to activate a ready mode, the ready mode causing the system to perform at least the following prior to turning the toothbrush on: switching on one or more of the electric loads for a preset period; enabling a wireless communication link between toothbrush and device; and exchanging data between toothbrush and device as part of the wireless communication.
摘要:
A mechanical toothbrush, including a housing portion extending along a longitudinal axis, a bristle shaft assembly including a shaft portion disposed within the housing and extending along the longitudinal axis, and a head portion disposed outside of the housing and having a plurality of bristles extending perpendicularly to the longitudinal axis around a circumference of the shaft portion, and an electronic controlling mechanism disposed within the housing portion, the electronic controlling mechanism activating the bristle shaft assembly to rotate about the longitudinal axis.

This invention is a toothbrush with usage indicator for use in connection with personal dental hygiene. Most people continue to use the same toothbrush, even when it no longer provides the quality needed to maintain good dental hygiene. An old toothbrush typically has worn bristles which fail to clean the teeth and gums properly. In addition, a toothbrush that has been used for a long time tends to have a build up of bacteria on it, posing a potential health problem for the user. The toothbrush with usage indicator has particular utility in connection with knowing when it is time to replace a toothbrush, employing a battery-operated counter which turns on a red light when the toothbrush needs to be discarded. The counter is loaded with a predetermined value, for example 45, which correlates to the number of times the toothbrush should be used before being discarded. A push button on the handle of the toothbrush allows the user to decrement the counter each time the toothbrush is used. While the counter value is 4 or greater, a green light is displayed, but when the value drops below 4, a red light is displayed. The red light indicates that the toothbrush should be replaced.
摘要:
Improved analytical, diagnostic, monitoring, and other methods (and their associated devices) for evaluating the extent of deposition of an agent onto a substrate are described. Exemplary methods may be used in the in the monitoring of the dental health of patients or in the fast, efficient screening and/or characterization of formulations in terms of their use for depositing oral actives onto tooth surfaces. The methods involve the direct or in situ analysis of substrates, onto which agents are deposited, using Near-IR spectroscopy and/or UV spectroscopy.
摘要:
An oral care apparatus includes: a care member; an orientation detection unit; an area estimation unit; a light source that emits light having a predetermined wavelength to which plaque reacts; a photoelectric conversion unit that receives light and converts the received light into an electric signal; an image capture unit that causes the light source to irradiate the care area with light, and that obtains image data, based on the electric signal of light reflected from the care area that is converted by the photoelectric conversion unit; a plaque detection unit for detecting an amount of plaque in the care area, based on the image data obtained by the image capture unit; and a storage unit for storing, in a memory, the care area estimated by the area estimation unit and the amount of plaque in the care area detected by the plaque detection unit in association with each other.
摘要:
Devices and methods for cleaning an oral cavity by positioning a device suitable for detecting and removing plaque from the surface within the oral cavity having applied thereto a fluorescent agent capable of binding to plaque on the surface. The surface is substantially simultaneously cleaned and irradiated with a light of a wavelength effective to provide a fluorescent emission when contacted with said fluorescent agent. A portion of the fluorescent emission is collected (APV1), and compared to a predetermined threshold value (PPTV). If APV1 is less than PPTV, the device is moved to another section. If APV1 is greater than or equal to PPTV, then another portion of fluorescent emission is collected (APV2). The percent reduction from APV1 to APV2 determines when the device is moved to another section.
摘要:
An interactive toothbrush is provided. The toothbrush may include memory including a set of instructions and at least one processor. The set of instructions, with the at least one processor, may be configured to cause the toothbrush to display a list of option to a user via a display panel when a switch to power on the apparatus is pressed. The set of instructions, with the at least one processor, may further be configured to cause the toothbrush to perform an action when a selection from the list of options is received from a user via the display panel. In some embodiments, the set of instructions, with the at least one processor, may further be configured to cause the toothbrush to detect the brushing habits of the user and transmit the brushing habits to another device.
