Abstract: An electrical discharge irrigation includes a power source to produce a first voltage, a circuit coupled to the power source to convert the first voltage to a second voltage, a discharge capacitor to receive the second voltage from the circuit, a transistor and/or a controlled rectifier coupled to the discharge capacitor to receive the second voltage, and an output tip. This tip is coupled to a transistor and/or a controlled rectifier and includes a first end, a second end, a longitudinal axis extending between them, an electrode located in an interior space of the tip to receive an electrical charge from the a transistor and/or a controlled rectifier and to release an electric discharge, and a ground return. The ground return is an outside surface of the tip. A space between the electrode and the ground return holds a conductive medium in contact with the electrode and the ground return.

Abstract: The present disclosure relates to a patient anxiety management system for managing patient anxiety during a dental procedure. In one example, a patient anxiety management system is presented. The patient anxiety management system includes a control module that a patient can use to disactivate a medical device used by a dental professional by way of a trigger mechanism. Upon deactivating the medical device, a recording device, in communication with the control module, plays a recorded message to the patient during a programmable timeframe. Once the patient is calm, the system resets the medical device to an initial operation state by reconnecting but not reactivating the medical device so that the dental professional may resume the procedure when it is safe to proceed.

Abstract: In a method and system for performing a treatment on a tooth, ultrasonic energy is generated and transmitted by an ultrasonic instrument to a fluid located in the interior of the tooth. The amplitude and frequency of the ultrasonic energy causes inertial cavitation of gas vesicles located in bacteria present in the fluid to assist in cleaning, disinfecting, and/or delivering a payload to the fluid and interior of the tooth but is below the safety limit for ultrasonic imaging.

Abstract: A root canal therapy device with a mechanical vibration mode and a rotation drive mode includes a head, a handle, a first flexible drive shaft and a second flexible drive shaft. The head includes an outer main part, a mandrel part for mounting a root canal file, a first drive input shaft part and a second drive input shaft part. The mandrel part is mounted in the outer main part. A first drive motor and a second drive motor are disposed on the handle. The invention has the following beneficial effects: the root canal file can rotate and vibrate during root canal preparation, so that the wall of a root canal is efficiently cut by the file; and the file can also vibrate, so that cutting resistance and cutting temperature are effectively reduced, a smear layer is avoided, and the quality and efficiency of root canal preparation are improved.

Abstract: The present disclosure provides a device having a circuit. The circuit includes at least one boost converter receiving power from an energy source, a square wave driver in series with the boost converter, an inductor in series with the square wave driver for converting a square wave to a sinusoidal wave, and a piezoelectric transducer in series with the inductor, the piezoelectric transducer connectable to a load. The device further includes a phase-locked loop coupled to the circuit to determine a resonance frequency of the piezoelectric transducer when the piezoelectric transducer is connected to the load.

Abstract: Various apparatus and methods for cleaning teeth and gingival pockets are disclosed herein. A fluid platform can include a pressure wave generator configured to propagate pressure waves through a treatment fluid. The pressure waves may be sufficient to remove undesirable dental deposits from a treatment tooth, neighboring gums, and/or spaces between the tooth and gums.

Abstract: An ultrasonic root end retro-preparation endodontic apical surgical instrument. The instrument has a double-angled shape with a length of between about 1-2 in (2.5-5.1 mm), and is made of a metal which safely and effectively propagates ultrasonic energy from a base segment to a bent distal tip with a length of between about 0.08-0.15 in (0.20-0.38 mm). The instrument includes a swivel segment that permits rotation of the bent distal tip of up to 360°. By allowing the bent distal tip to be swiveled, the instrument may be used for all quadrants, anterior and posterior teeth without switching out the instrument for another one.

Abstract: Various mechanical drive devices, mechanical gears, combinations thereof and medical or dental treatment devices with such mechanical drive devices or gears are described. The mechanical drive devices and mechanical gears convert a unidirectional rotational movement received by a motor drive into a multidirectional movement, so that a tool-holding device of the treatment device can be induced to a multidirectional movement, in particular to a, preferably simultaneous, lifting and rotating movement or to a lifting and oscillating rotational movement with a reduced rotational speed.
