A super-fine bubble generation apparatus includes a fine-array porous membrane and a device for generating substantially uniform, super-fine gas bubbles in a liquid. The fine-array porous membrane includes a plurality of pores having a substantially uniform size of <100 m, with a variation of <20%. The super-fine gas bubbles generated by this apparatus can have a size of 50 nm-50000 nm, with a substantially uniform distribution with variations <20%. Applications of such super-fine bubble generation apparatus can include a skin cleansing device, or a teeth-cleaning device.

A directional guide for use with an air-water tip for a syringe includes an elongated member fixedly attached to a longitudinal section of the air-water tip. Extending outwardly from the elongated member is a position control member. The position control member is formed and positioned to rotate the elongated member and the air water tip together and to selectively activate air-water buttons on a syringe.

A non-invasive dental or surgical monitoring system is disclosed. The monitoring system is comprised generally of dental or surgical equipment to be monitored, a main sensor unit, a set of sensors. The main sensor unit is in communication with various sensors removably attached to the equipment. The sensors monitor environment conditions related to the equipment rather than directly monitoring the equipment. The collected data is sent to the main sensor unit and can be accessed, or wirelessly transmitted by signal to a device or devices at another location. As collected data aggregates, a data profile can be created, machine learning can be used to discover patterns, and predictive analysis can be incorporated to help software make predictions of, or spot in real time, equipment problems based on deviations from the profile.

An intra oral scanner (IOS) including a probe is disclosed. Optionally, the probe is calibrated to measure locations at a higher accuracy than the IOS. For example, the probe may be used to locate points in a 3D map at high precision and/or the points used to increase the precision of location of other points and/or surfaces in the map. In some embodiments, the probe includes a sensor. Optionally, the probe may be used to measure locations that are hard to view with the IOS. For example, the IOS probe combination may be used to produce 3D maps of a recess in a tooth and/or gums and/or a periodontal pocket and/or to traduce a 3D map or periodontal disease. In some embodiments the probe may be used to measure physical properties, for example, the IOS probe combination may be used to produce a 3D image of hardness of mucosa.

A device, method, and system are provided for aiding the whitening of teeth. The device includes a mouthpiece suitable for implementing a dental treatment, wherein the mouthpiece includes one or more stock elastomeric dental cover layers suitable for forming and maintaining a treatment cavity having a vacuum fluid seal, wherein the dental cover layers includes a layer over the upper teeth and surrounding gums and/or a layer over the lower teeth and surrounding gums, wherein each of the layers includes one or more hardened sections for enabling selected/differential collapsibility when exposed to vacuum pressure; and one or more treatment supply layers wherein the treatment supply layer incorporates a heating unit for heating treatment materials and one or more flow channels in fluid communication with the treatment cavity so that the treatment supply layer can deliver and/or remove one or more treatment fluids from the one or more fluid sealed treatment cavities.

A device comprises a plurality of electroactive material actuator units arranged as a linear set. Data for controlling the driving of the individual units is provided on a data line, and data line connections are made between each adjacent pair of electroactive material actuator units. The electroactive material actuator units are controlled in dependence on received data from the data line. This provides a reduced complexity of the wiring when multiple actuators need to be addressed and controlled in small application environments.

An apparatus and method for purging a dental air/water syringe comprises at least one of a button hold-down device for holding down at least one button of the syringe for discharging fluid therefrom and a collection container for collecting the discharged fluid. The button hold-down device includes axially spaced contact surfaces for contacting a syringe body and the button so that the device is supported mounted on the syringe body in a working position. The collection container features an interior perforated false bottom wall under which is formed a collection space where the discharged fluid collects, and a drain is communicated with the collection space for removing the collected fluid therefrom. The drain can be connected to a saliva ejector for removal of the fluid by suction.
