Abstract: An oral care device (8) for use in aiding delivery of a substance for an oral treatment purpose within the mouth. The device comprises a field generator (16) which is adapted to generate a field (20) for exerting a force on particles (20) susceptible to the field to guide movement of the particles to a desired location. When operated in the mouth, this allows oral treatment particles to be quickly, safely and efficiently distributed within the mouth to the correct locations for performing the oral treatment function.

Abstract: An oral care device has a field generator adapted to generate an electric field in a mouth of a user, responsive to an input control signal. The electric field is for imparting a force upon particles forming a biofilm to be removed by the oral care device or upon cleaning agent particles. A cyclic control signal is generated for intermittent generation of an electric field at a first RF frequency. The use of an intermittent generation of an RF electric field means the force applied to particles (in particular polarized particles) by the field is itself cyclic. The cyclic nature of this applied force is found to be more effective in the disintegration of a biofilm to be removed, and hence makes subsequent mechanical removal, e.g. by brushing, easier.

Alternatively, one or more inlets may have openings with variable cross-sectional area, like e.g. an adjustable diameter of their opening, and also a combination of these two alternatives is of course possible.

Abstract: 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.

The device includes means, either mechanical or electrical, for varying a generated RF field pattern (e.g. spatial intensity distribution) between different settings. The device is in particular configurable in at least two modes or settings, each associated with a different respective field pattern or spatial intensity distribution. This is valuable for adapting the cleaning functionality to different required purposes.
