An oral irrigator includes a base having a pump mechanism, a reservoir housed within the base and fluidically connected with the pump mechanism. A handle with a jet tip is connected with an outlet from the pump mechanism to receive a pressurized fluid stream from the reservoir to direct a fluid at a surface inside an oral cavity. The oral irrigator also includes a radiant energy source and delivery system for directing radiant energy at a surface inside an oral cavity.

A smart phone or tablet includes laser diodes, at least some of which may be pulsed and generate near-infrared light and include Bragg reflectors to direct light to tissue/skin. An array of laser diodes generates near-infrared light and has an assembly in front of the array that forms the light into a plurality of spots on the tissue/skin. A receiver includes detectors that receive light reflected from the tissue/skin. An infrared camera receives light reflected from the tissue/skin and generates data based on the received light. The smart phone or tablet is configured to generate a two-dimensional or three-dimensional image using at least part of the data from the infrared camera.

Method of treating oral subgingival biofilms having obligate anaerobes, facultative anaerobes, aerobic bacteria and other micro-organisms (collectively oral pathogens) associated with certain systemic diseases present within a subgingival biofilm having proteins and amino acids, the steps including providing a periodontal medicament delivery tray having a seal against a patient's adjacent gums containing the oral biofilms with the systemic disease, said seal formed so as to have no contact with teeth, applying to the gingival tissue (sulcus or periodontal pocket) a biofilm penetrating antimicrobial agent, removing the imbedded oral pathogens from the gingival tissue following at least one applying of the antimicrobial agent to the gingival tissue; repeatedly administering colloidal hydrogen peroxide gel to the gingival tissue following the removing; and following each administering cleaning the gingival tissue with a cleaning agent directly following the administering of the colloidal hydrogen peroxide gel for modifying the environment from anaerobic to commensal.

A medical treatment apparatus includes a power and control (PAC) device. The PAC device provides electrical power through a cable to a laser handpiece assembly to electrically power a laser source within the handpiece assembly. The PAC device controls operation of the handpiece assembly and detects an identification of the handpiece assembly. The PAC device also monitors data relating to operation of the handpiece assembly. The PAC device uploads, through a communication network to a user assistance center remote from the PAC device, the handpiece assembly identification and the monitored data.

An apparatus for cooling tissues which are treated with an energy-based device, such as a laser, is disclosed. The apparatus comprises a spray nozzle which generates an atomized liquid spray for the treatment area, wherein the atomized liquid spray is based on a mixture of liquid and gas. Further, the spray nozzle comprises at least one liquid outlet which ejects a liquid, and at least one gas outlet which ejects a gas stream. Besides, the apparatus for cooling comprises at least one delivery means for delivering pressurized gas to the spray nozzle; and a pumping means for the liquid, wherein the pumping means is configured to operate in pulses.

In some aspects, the techniques described herein relate to a dental restoration device for a full-mouth dental replacement, including: a body extending between a gingival side and an occlusal/incisal side, wherein the body includes a plurality of teeth portions each having a tooth axis extending between the gingival side and the occlusal/incisal side that is offset from vertical; an ovate gingival contour defined on each tooth portion on the gingival side of the body; and at least first and second abutment holes extending through at least first and second teeth portions from the gingival side to the occlusal/incisal side, wherein each of the first and second abutment holes includes a longitudinal axis that is substantially coaxially aligned with the tooth axis of the first and second teeth portions, respectively.

A laser and a minimally invasive dental surgical procedure using the laser to stimulate periodontal tissue formation.

A system and method for dental or surgical treatment of oral tissue, the system including a laser source; a hand piece; and a device for directing radiation emitted by the laser source to a treatment area (e.g., an oral treatment area), the device further including a disposable tube attachable to the hand piece and an optical element (e.g., a substantially cylindrical lens) mounted within the disposable tube and adapted to modify a profile and/or a direction of the radiation emitted from the tube.

An optical system comprises a wearable device for measuring one or more physiological parameters. The physiological parameters may change in response to stretching of the hand or movement of fingers or thumb of the user, or the parameters may be related to blood constituents or blood flow. The wearable device comprises a light source with a plurality of semiconductor diodes and a detection system that measures reflected light from tissue comprising skin. The semiconductor diodes may be light emitting diodes or laser diodes. The signal to noise ratio for the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity of at least one of the plurality of semiconductor diodes from an initial light intensity, and using change detection that compares light on versus light off for the detection system output. The wearable device is also configured to identify an object.

Medical apparatuses with selectively dimmable displays are disclosed herein. Some embodiments include a housing, a laser surgical handpiece device, a laser source that generates laser light that is emitted through the laser surgical handpiece device, an electroluminescent display associated with the housing, the electroluminescent display being configured to display operational settings for the laser source, the operational settings including at least power level and pulse width or duration, and a microprocessor for controlling the electroluminescent display to selectively illuminate or dim at least a portion of the operational settings displayed thereon based on the operational settings selected by a user.
