A dental health and care system utilizes an image capturing module installed on a teeth cleaning device in order to capturing teeth images during the cleaning of teeth of a user. Teeth images can be submitted to a care service center to determine whether the oral care is proper performing, the teeth is cleaning, and any symptom is in the teeth thereof. In addition, it is able to further provide diagnosis recommendations containing medical treatment information in order to timely report to the care giver of the child, elderly or care receiver or to the user for improvement on the health habit or as outpatient reference. Professional consultation and recommendation can also be provided in order to achieve the effect of providing assistance to the user or the entire family members in their understanding of the dental health and care condition through daily teeth cleaning actions with ease.

A smart toothbrush system, utilizing fluorescence and an intraoral camera, includes a toothbrush handle with embedded electronics, detachable brush and intraoral camera heads, and wireless connectivity capability for communication with external devices. The detachable brush head system is capable of directing particular wavelengths of light to the oral cavity, producing visible fluorescence when incident upon certain biomaterials that are indicative of the presence of various dental conditions. The intraoral camera head is capable of directing the same wavelengths of light to the oral cavity to produce the same fluorescing effect and can be used to closely inspect or record the presence of harmful biomaterials indicative of dental health.

A computer-implemented method of training a user to effectively apply makeup using a computerized makeup brush, the method comprising the steps of receiving, from a makeup brush movement tracking system that comprises one or more sensors for sensing the movement of the makeup brush relative to a particular portion of a user's body, data representing a movement of the makeup brush relative to the particular portion of the user's body over a particular period of time as the makeup brush is used to apply makeup brush to the particular portion of the user's body, and using the data to generate and display, to a user, a visual representation of the movement of the makeup brush over the particular period of time on a suitable display (e.g., while providing appropriate visual or audio feedback on the user's performance in applying makeup and/or proper makeup application techniques).

A brushing apparatus includes a head and a handle extending out from the head. The head includes a plurality of bristles. A camera may be secured to the head of the brushing apparatus adjacent to the plurality of bristles. The system may further include a processor and a memory in communication with the processor. The memory contains instructions that, when executed by the processor, cause the processor to receive an image from the camera as bristles of the plurality of bristles are engaged with a body. Further instructions cause the processor to detect an atypical contour of the image that indicates a physical anomaly. Further instructions cause the processor to generate a notification in response to detecting the atypical contour that indicates the physical anomaly.

A brush of the present disclosure includes a head and a body. The head includes bristles extending in a first direction. The body includes an actuator configured to expand and contract in a second direction intersecting the first direction and a connection member configured to transmit vibration of the actuator to the head.

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.

A personal hygiene device has a drive unit having a support, a stator fixedly mounted at the support, and an armature spring-mounted at the support for driven linear oscillating motion along a first longitudinal direction parallel to or coinciding with an x-axis of an x-y-z coordinate system. The armature has a center of gravity located in rest at a coordinate [x.sub.a, y.sub.a, z.sub.a], and a drive shaft fixedly coupled with the armature and having a center of gravity located in rest at a coordinate [x.sub.d, y.sub.d, z.sub.d]. A first treatment head assembly, detachably connected to the drive shaft, has a center of gravity located in rest at a coordinate [x.sub.t1, y.sub.t1, z.sub.t1]. A secondary mass element, spring-mounted at the support for essentially linear oscillating motion along the first longitudinal direction, has a center of gravity located in rest at a coordinate [x.sub.m, y.sub.m, z.sub.m]. At least the coordinate [x.sub.a, y.sub.a, z.sub.a] of the center of gravity of the armature has an offset in at least one of the y-direction and z-direction with respect to the coordinate [x.sub.d, y.sub.d, z.sub.d] of the center of gravity of the drive-shaft or with respect to the coordinate [x.sub.t1, y.sub.t1, z.sub.t1] of the center of gravity of the first treatment head assembly, i.e., y.sub.ay.sub.d and/or y.sub.ay.sub.t1 and/or z.sub.az.sub.d and/or z.sub.az.sub.t1; and the secondary mass element is configured such that the coordinate [x.sub.m, y.sub.m, z.sub.m] of the center of gravity of the secondary mass element is aligned with the coordinate [x.sub.j, y.sub.j, z.sub.j] of the joint center of gravity of the drive shaft, the first treatment head assembly and the armature in the at least one offset direction, i.e., y.sub.m=y.sub.j and z.sub.m=z.sub.j, so that a line connecting the coordinate [x.sub.m, y.sub.m, z.sub.m] of the center of gravity of the secondary mass element and the coordinate [x.sub.j, y.sub.jz.sub.j] of the joint center of gravity is parallel to or coincides with the x-axis.
