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.

An electric toothbrush having bristle driven pulsation includes a brush head having a bristle holder and bristle tufts attached to the bristle holder. The bristle tufts and corresponding bristles are disposed at a perpendicular and/or a non-perpendicular angle with respect to a mounting surface of the brush head. The electric toothbrush also includes an electric toothbrush handle removably attached to the brush head. The electric toothbrush handle includes a linear motor configured to drive the bristle holder via a gearing structure coupled to the linear motor and the bristle holder. The linear motor causes the bristle holder to rotate clockwise and counterclockwise at a rotation frequency which exceeds a rotation frequency threshold (e.g., 100 Hz, 120 Hz, etc.). The linear motor also causes the brush head to vibrate in a direction toward and away from a contact surface in synchronization with the rotation of the bristles.

In one embodiment, the invention can be a brush unit detachable from a main body unit of an electric toothbrush. The brush unit includes: a light transmitting part included on a front surface of the brush unit, a plurality of tooth cleaning elements extending from the front surface of the brush unit in a pressing direction, wherein the light transmitting part directs more light in a first direction, which intersects the pressing direction, than in the pressing direction; and a light receiving part included on the front surface for receiving light; wherein the light transmitting part and the light receiving part are arranged on opposing sides of the plurality of tooth cleaning elements; and wherein the first direction lies within a plane including both the light transmitting part and the light receiving part.

A toothbrush, which can be operated by a child, having a built-in light source, and includes an operation button that controls a light emission mode of the light source. The light source can emit light in a multicolor light mode, switchably emitting light in at least three or more colors, and a monochromatic light mode, emitting light in a particular color selected from the at least three or more colors in a fixed manner.

An oral care implement comprises a head with a plurality of cleaning elements, the head comprising a chamber. The oral care implement may include a reflective or refractive membrane positioned within the chamber. A light source may also be positioned within the chamber such that light from the light source is directed at the reflective or refractive membrane. The oral care implement may also include a head plate with a plurality of tooth cleaning elements coupled thereto, the head plate positioned over the chamber. The light from the light source may be emitted through the head plate. In some embodiments the oral care implement may be a toothbrush. In other embodiments the oral care implement may be non-toothbrush type implements that include a body forming a chamber within which the lighting components are positioned.

An electric toothbrush includes a grip portion, a brush portion on which a replaceable toothbrush is mounted, and an illumination ring between the grip portion and the brush portion. The illumination ring is provided around the toothbrush as an annular structure so that a user can view the illumination ring no matter what angle he/she is holding the toothbrush.

A makeup applicator for use by individuals to apply, touchup or reapply makeup, especially liquid or cream makeup, and further especially for use relating to lipstick, is disclosed. The compact makeup applicator is designed with at least two separable ends or covers, that may be used as an ergonomic base or support for optimal use of the makeup applicator. In one embodiment, one type of separable end may comprise a flexible balloon to contain a small amount of a liquid or cream makeup for use to touchup or reapply the makeup. In a storage configuration, the separable end snuggly attaches to the applicator base to cover the applicator brush or bristles. For normal usage, the separable end may be removed from the applicator base, exposing the applicator brush or bristles, and is attached to the other side of the applicator base to provide an ergonomic support or base extender.

The invention relates to a hand-held device for excitation and irradiation of pathogenic microorganisms in the mouth and throat, e.g. a toothbrush comprising at least one excitation light source in the short-wave visible spectral range for auto-fluorescence excitation of the pathogenic microorganisms, at least one primary irradiation light source in the red spectral range for primary irradiation of the pathogenic microorganisms and for transillumination, and optionally at least one secondary irradiation light source in the visible spectral range for secondary irradiation of the pathogenic microorganisms, wherein the irradiation light sources have spectral components that can be absorbed by endogenous porphyrins, which are produced by the pathogenic microorganisms, whereby a fluorescence excitation and an inactivation of the pathogenic microorganisms occurs on the basis of subsequent processes. In order to prevent the unintentional irradiation of the eyes, a pressure sensor is designed to release higher light intensities only once a contact pressure has been measured. In addition, the radiation must leave the hand-held device in a divergent manner. The spatially resolved detection of the fluorescence of the pathogenic microorganisms can optionally be used to induce the inactivation of the bacteria by targeted irradiation in the fluorescent range.

The present invention relates to an electric toothbrush that includes an outer case including a handle part having a tubular shape, and a head part extending from the handle part and having an opening area open to front; first and second electrodes disposed in the opening area and providing electromagnetic waves corresponding to a driving signal; and a head cover having a plurality of bristle holes, a first electrode hole, and a second electrode hole, which are formed therein, and closing the opening area. The first and second electrodes may penetrate the first and second electrode holes, respectively, and be exposed to outside.
