An oral care system for sensing blood in an oral cavity and in gum tissue. The sensing is performed magnetically using a magnetic field source () and magnetic sensing arrangement () incorporated into a cleaning or treatment portion of an oral care device (e.g. a brush head of a toothbrush or mouthpiece part of a brushing mouthpiece device). The field source generates () a reference field and the sensing arrangement () is arranged to sense the field strength of the reference field at one or more spatial points. Since blood is magnetic, when brought into the reference field, it magnetically interacts with the field, which may alter field strength, field shape, or flux distribution. This enables presence of blood to be detected. It also allows for detecting specific oral features or disease states associated with presence of blood or abnormal amounts or concentrations of blood. For example, this can be based on application of detection criteria which relate to one or more properties of the sensed field.

Oral care device with sensing functionality

The invention provides a mouthpiece for dental cleaning system and the dental cleaning system itself. The mouthpiece has a base and inner and outer arches. An actuator is for applying motion to the inner arch and/or the outer arch, relative to the base. A coupling arrangement converts motion of one of the inner and outer arches in one direction relative to the base to motion in an opposite direction relative to the base of the other of the inner and outer arches. By forming the mouthpiece as a central stationary base enveloped by two contour-following and moving arches, an anti-phase brushing motion at opposite tooth sites along the tooth arch is enabled, giving increased reach toward the molars as well as a reduction in device vibration in the mouth.

Mouthpiece for a dental cleaning system and the dental cleaning system

A system for oral irrigation comprises a fluid delivery tube with a proximal end and a distal end. The proximal end is configured to receive fluids for oral irrigation. The system also comprises a nozzle at the distal end of the fluid delivery tube with an aperture for fluid delivery. The nozzle is configured to at least partially obstruct the flow of fluid from the fluid delivery tube through the nozzle when the aperture is in contact with a tooth relative to when the aperture is away from said contact. A pump is configured to pump fluids through the fluid delivery tube based on a pump configuration and a sensor is used for sensing a pressure or flow rate in the fluid delivery tube. A controller is configured to detect whether the nozzle is in an interdental space based on the sensor detecting a pressure drop or a flow rate increase in the fluid delivery tube and adjust the pump configuration based on the nozzle being in an interdental space.

There is also provided an oral care system and a kit of parts, and a computer implemented method for an oral care device.

Oral care system for interdental space detection

A personal care device () comprising an RF signal generator () for generating RF-frequency electromagnetic emissions for a cleaning or treatment function. The RF emissions may be output from a set of two or more RF electrodes () (e.g. electrodes) upon stimulation with an RF drive signal in a frequency range from 3 kHz to 30 GHz from an RF signal generator. The device further includes a controller () for detect a degraded functional state of the RF electrodes () via monitoring changes or variations in one or more electrical characteristics of the RF signal generator (), e.g. drift in one or more electrical characteristics from reference factory levels, or sudden changes in the characteristics, indicating a short-circuit. A response action can be generated based on the electrical characteristics meeting pre-defined criteria indicative of a certain degraded functional status, for example generating a sensory alert for a user or data output, or performing remedial action such as deactivating sensed defective or worn electrodes.

A new method and a system for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The device includes a dispensing unit for the composition, a distal end of which is adapted to apply the composition onto teeth or gums. The device further includes an electrode system having first and second electrodes, the first electrode adapted to be held against the composition at a location at or near teeth or gums, and the second electrode adapted to be held against the composition at a location away from teeth or gums. The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the first and second electrodes.

Method and system for oral PH change

Disclosed is a method, and a system, for accomplishing the in situ formation of a gel in an interdental space. This is useful for the interdental application of one or more dental care agents, such as antimicrobial agents or other anti-plaque agents. The invention makes use of a two component system comprising a gelable liquid and a liquid gelling agent capable of bringing about gelation of the liquid. The system of the invention is arranged such that first the gelable, typically viscous, liquid can be applied, and then the liquid gelling agent is forced, e.g. jetted, into the applied gelable liquid. The system is designed such as to prevent the gelling agent and the gelable liquid to come into contact with each other before both have been applied. The system is configured to allow the gelable liquid to be applied prior to the gelling agent.

Administration of oral care agents

Disclosed is a system and method for the delivery, into interdental spaces, of oral care active agents contained in particles. The particles are made of one or more superabsorbent polymers (SAP), and are of size generally small enough to be easily applied into an interdental space. To this end, the particles typically have a length of below 1.5 mm. By virtue of the SAP's ability of absorbing several times its own weight in water, the particles will swell once in contact with saliva. As a result, the volume of the particles as applied in between teeth increases by at least eight times, thereby effectively making the particles larger than the average interdental gap size. The particles, once swollen, are thus held more firmly between the walls of the interdental space, thus preventing them from being easily washed away.

Oral care particles and system for the administration thereof

Droplet jet system for cleansing

The method for cleaning dental plaque biofilm from the teeth includes the steps of applying a liquid gellable composition to the teeth, the composition including a positively charged polymer such as chitosan, the liquid composition having a viscosity which results in coverage of substantially all of the exposed areas of the teeth. The liquid composition is then gelled by the addition of a second composition, such as a negatively charged compound. The resulting gelled composition has an adherence to the plaque biofilm which is greater than the adherence between the biofilm and the teeth. The gel layer with the biofilm is peeled off of the teeth, removing the dental plaque.
