A method and system for monitoring the location of an oral care device (102) within the mouth of a user, includes: an oral care device (102) having a light source (104); an optical sensor (112) configured to receive light emitted by the light source and to receive light reflected from a user using the oral care device; a computing device (110) adapted to receive and process signals generated by the optical sensor, and programmed to: detect at least one facial feature of the user from the received light reflected from a user; estimate the location of the user's teeth according to the detected facial feature; determine a location of the light source according to the received emitted light; compare the location of the light source to the location of the teeth to estimate the position of the oral care device with respect to the teeth of the user.

Embodiments of the disclosure provide a video toothbrush. An exemplary video toothbrush may include a handle housing an exciter and a support element including a support neck and a support head. The support element may be configured to extend from a proximal connection with the handle to a distal end. The video toothbrush may further include a camera mounted near the distal end of the support head and a shaft extending from the support neck and configured to support a cleaning head toward a distal end of the shaft and configured to receive vibration from the exciter toward a proximal end of the shaft. The video toothbrush may also include the cleaning head having a plurality of bristles projecting in a first direction. The cleaning head may define a central opening. The central opening may be arranged to provide the camera with a view in the first direction.

An example embodiment of a dental tool includes a main body portion having a first longitudinal end and a second longitudinal end, wherein the first end and the second end define respective reduced diameter portions, two or more tool attachments, each tool attachment comprising a working portion and a base portion, the base portion configured to be removably coupled to either of the reduced-diameter portions of the main body portion so as to secure the tool attachment to the main body portion, and a light source, disposed within the main body portion, arranged so as to illuminate the working portion of one of the tool attachments when the one of the tool attachments is coupled to the first end of the main body portion and the light source is electrically coupled to a power source.

A powered scrubbing wand assembly for scrubbing a surface includes a handle that can be gripped during cleaning activities. A cleaning head is coupled to the handle and a drive unit is integrated into the handle. The drive unit rotates in a first direction when the drive unit is turned on. A spray unit is integrated into the handle for spraying a fluid soap when the spray unit is turned on. A plurality of scrubbers is each removably attachable to the cleaning head. The drive unit rotates the scrubber on the cleaning head when the drive unit is turned on thereby facilitating the scrubber to scrub a surface.

The makeup application brush with detachable illuminated mirror is comprised of a cosmetic brush and a lighted mirror integrated into one device. The lighted mirror is attached to a proximal end of the makeup application brush handle with the makeup brush head at a distal end of the makeup application brush handle. The makeup application brush is separated by screwing apart the handle for independent use of the lighted mirror or cosmetic brush. The lighted mirror segment is powered by USB charging. With the provision of visibility and lighting from the lighted mirror, the makeup application brush can be used for makeup application or makeup removal. The makeup application brush is innovative in the beauty industry field by combining two beauty accessories: a lighted mirror and a makeup application brush into one device.

A brush for cleaning a periodontal pocket between a tooth and a gum of a user. The brush includes, at least, a handle portion, an arm extending from the handle portion, and a brush head located at an end of the arm having a plurality of brush filaments extending therefrom. The brush filaments are configured to be inserted into a periodontal pocket. The brush can be used to assist in the treatment of gum disease by enabling a user to precisely clean periodontal pockets. The brush may be for self-use. Alternatively, the brush may be used by a healthcare professional such as a dentist or hygienist to treat a patient or to demonstrate its use.

A plaque detecting device including a light emitting unit which irradiates light toward a tooth, and first and second light receiving units which receive radiated light from the tooth. The first light receiving unit extracts the spectral component of a first wavelength region containing fluorescent light specific to plaque and obtains a first output value corresponding to intensity of that spectral component. The second light receiving unit extracts the spectral component of a second wavelength region containing fluorescent light specific to enamel and obtains a second output value corresponding to the intensity of this spectral component. Determination of the relative magnitude of the ratio between the first output value and the second output value as compared to a first threshold value is performed. Determination of the relative magnitude of the difference between the first output value and the second output value as compared to a second threshold value is performed.

A method and apparatus for illuminating a broom or mop, the method includes providing a mount. The mount has a first adjustable rod clamp, the adjustable rod clamp having an opening sufficiently large to hold a broom or mop handle, the first adjustable rod clamp attached to a second rod clamp by an articulating joint. The articulating joint allowing at least rotation between the first rod clamp and the second rod clamp. The second rod clamp has an opening sufficiently large to hold a flashlight. The method further includes mounting the first adjustable rod clamp on a broom or mop and mounting a flashlight on the second rod clamp.

Systems and methods for measuring and indicating brush head life are disclosed. In one embodiment, the system includes a brush head that moves with respect to a brush handle; an energy harvester that generates electrical signals based on movements of the brush head; a controller in electrical communication with the energy harvester; and an indicator in electrical communication with the controller. The indicator is energized based on a signal from the controller.

A toothbrush includes a main body that includes a head portion with a bristle raising surface on which bristles are provided in a standing manner, a grip portion, and a neck portion. A light emission portion that emits light through a specific region of the bristle raising surface toward a tooth surface and a light reception portion that receives radiated light from the tooth surface resulting from the light, through the specific region, are provided inside of the main body. It is determined whether or not there is dental plaque on the tooth surface based on the output of the light reception portion. A light reception and condensing portion that condenses the radiated light from the tooth surface toward the light reception surface of the light reception portion is arranged in the housing portion forming the specific region.
