A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

An oral cavity treatment device including a power component and a tray component that are detachably coupled together. The power component may include a housing having a cavity and a power source located therein. The tray component may include a tooth receiving channel and may have a first electrode and a second electrode located on opposite sides of the tooth receiving channel. The tray component may be detachably coupled to the power component in: (1) a first configuration whereby the first electrode is operably coupled to a positive terminal of the power source and the second electrode is operably coupled to a negative terminal of the power source; and (2) a second configuration whereby the first electrode is operably coupled to the negative terminal of the power source and the second electrode is operably coupled to the positive terminal of the power source.

Two-piece bilateral illumination attachment for dental camera is a light source that is reversibly attachable to any dental camera. Two-piece bilateral illumination attachment for dental camera has two light sources that directly face each other. When properly attached to a dental camera, two-piece bilateral illumination attachment for dental camera effectuates sub-enamel illumination or bilateral illumination of a tooth, so that the dental camera may capture a photo or image of the illuminated tooth. Two-piece bilateral illumination attachment for dental camera has a specially shaped body that makes a slip-fit, press-fit, or snap-fit onto the exterior surface of any dental camera. Two-piece bilateral illumination attachment for dental camera has a distal section and a proximal section. The distal section is reversibly attachable to the proximal section. The distal section is sterilizeable.

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 electric toothbrush disclosed herein includes a vibrator having a housing and a motor. The housing encloses the motor and a portion of a switch operably coupled to the motor. The electric toothbrush also includes a head portion including a brush. A cap is coupled to the head portion. The head portion and the end cap enclose the vibrator.

A personal-care device has a rechargeable energy storage, a charging circuit for receiving energy from an external energy source and for charging the rechargeable energy storage, a first charging mode in which the rechargeable energy storage is charged to a predetermined maximum voltage value, and a user-selectable second charging mode in which the rechargeable energy storage is charged until the voltage at the rechargeable energy source has reached a first predetermined voltage value that is lower than the predetermined maximum voltage value. The present disclosure is also concerned with a system having such a personal-care device and a charger.

By using techniques to diverge an emitted beam, the same base device may be utilized as either a cutting laser or a curing light. The use of multiple frequency laser modules (312) and a selection of emitter heads (304) allow for systems (300) which may be used for a wide variety of medical and dental procedures. Each system (300) has a plurality of emitter heads (304) to select from either a curing light, a cutting laser, or any other therapeutic energy emission all while utilizing the same laser module (312). Various structures of emitter heads are disclosed, as well as laser modules and connection strategies.

An electric toothbrush includes a head unit and a handle unit. The handle unit is detachably combined with the head unit, and supplies a driving voltage to the head unit in response to a user's manipulation. When the handle unit is partially inserted into the head unit and then rotated with respect to the head unit, the handle unit is electrically connected to and mechanically engaged with the head unit.

A system comprises a dental tray comprising an array of fixed focus cameras, wherein each fixed focus camera of the first array of fixed focus cameras has a fixed position and orientation relative to one or more other fixed focus camera of the array of fixed focus cameras. The system further comprises a processing device to receive a plurality of images generated by the array of fixed focus cameras, stitch the plurality of images together based on calibration data specifying predetermined image stitching parameters for combining the plurality of images, wherein the predetermined image stitching parameters are based on predetermined fixed relative positions and orientations of fixed focus cameras from the array of fixed focus cameras, and generate a three-dimensional model of a plurality of teeth based on the stitched plurality of images.
