A dental handpiece includes a head portion supporting a turbine for a removable rotating dental tool, and a handle portion having an internal cavity. One or more conduits extend at least partially through the internal cavity toward the head portion. At least one of the conduits is a drive fluid tube delivering drive fluid to the head portion for rotating the turbine. A wireless communication device within the internal cavity is attached to at least one of the conduits. At least a section of the handle portion surrounding the wireless communication device is formed of a dielectric material. The wireless communication device is configured to wirelessly communicate with an external reader or writer and store data related to at identification, use, and/or maintenance of the handpiece. An electrically inert substrate material encapsulates the wireless communication device, which is electrically isolated from other components of the handpiece.

A diode laser system having high-power diode(s) said high-power diode(s) producing laser outputs in a range of 0.1 to 25 Watts of power using optimum wavelengths via a single optical delivery fiber.

There is provided in accordance with an exemplary embodiment of the invention a method of osteointegration of an implant into surrounding jaw-bone, the method comprising: applying a magnetic field around an implant, the magnetic field produced around the implant to a jaw-bone depth of up to at least about 7 mm, the magnetic field having a magnetic flux density of about 0.05-0.5 mT at up to at least about 2 mm from a surface of the implant, the magnetic field produced by a coil within the implant. A device adapted for insertion into a jawbone implant and for producing the magnetic field for bone enhancement of surrounding jawbone is also described.

Provided is a vibrator for attaching composite resin to a tooth, the vibrator including a housing; a vibration motor accommodated in the housing and configured to generate vibration; a micro-computer configured to control an operation and a vibration frequency of the vibration motor; and a vibration tip configured to couple with one side of the housing to be exposed to an outside of the housing, and to transfer the vibration to the composite resin.

A medical or dental system with at least one first transmitting and/or receiving unit and at least one second transmitting and/or receiving unit, wherein the at least two transmitting and/or receiving units are designed for the capacitive coupling of electric signals into and/or out of a human body, so that an electric path which extends through the human body of the user and/or of the person to be treated can be established for the transmission of electric signals between the at least one first transmitting and/or receiving unit and the at least one second transmitting and/or receiving unit, in order to transmit data between the at least two transmitting and/or receiving units.

A system is disclosed. The system contains an instrument configured to fit in a patient's anatomy, an optical sensor associated with the instrument, a processing unit receiving data from the optical sensor, and a display displaying position of the instrument in the patient's anatomy based on the data from the optical sensor.

A method (30) for disinfection of a biofilm layer comprises thinning (34) the biofilm layer from an initial thickness to below a given thickness. The method further includes actively drying (36) the thinned biofilm layer for a predetermined active drying interval to disinfect and remove a substantial portion of the body of biofilm bacteria of the thinned biofilm layer. A device (50) for disinfection of a biofilm layer is configured for implementing the method.

A oral irrigator device (10) for cleaning teeth, including a system (14) for producing a stream of liquid/air bursts and a nozzle (16) connected to the system, and through which the stream of liquid/air bursts are directed. The nozzle can include a guidance tip (26) including a base portion (30), a tip portion (28), and an orifice (31) through which the stream of liquid/air bursts exits at a flow output pattern, and a flow output pattern selection mechanism (90, 90′) connected to or positioned within the guidance tip. A flow output pattern selection mechanism can be configured to be selectively actuated and to vary, upon the actuation the flow output pattern between a first flow output pattern to at least a second flow output pattern.

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.

There is a need for a minimally invasive surgical treatment method for periodontitis for the removal of deep pockets, elimination of disease, creation of reattachment of the gingiva to the tooth surface and true regeneration of the attachment apparatus (new cementum, new periodontal ligament, and new alveolar bone) on a previously diseased root surface. The PerioLase® MVP-7™ including eGUI or another device capable of laser dosimetry, such as an original MVP-7™ type laser without the eGUI, achieves this with the LANAP protocol (laser-assisted new attachment procedure) and the LENAP protocol (laser excisional new attachment procedure).
