Abstract: A brush for a sonic toothbrush with longitudinal axis vibration having an elongated base body has a frustoconical base portion with a drive adapter for rotation-fixed coupling to a sonic toothbrush drive with longitudinal axis vibration, and a head portion with a bristle support in which a plurality of bristles are anchored, and an elongated neck portion connecting the base portion and the head portion is disclosed. The base body forms a kink angle in that a geometric base portion longitudinal axis and a geometric head portion alignment axis include an angle ? in the range of 5° to 12°. A geometric kink position in the base body has a distance from an end face of the base portion of at least 50% of a total length of the base body.

Abstract: The present invention relates to an interdental brush (1, 1?) having a brush part (2) comprising two twisted-together legs (4A, 4B) of a wire section (4) and brush filaments (5) held clamped between the legs (4A, 4B), and to a method for producing such an interdental brush (1, 1?). In order to improve in particular the bending fatigue strength of the wire section (4), it is provided according to the invention that a wire section (4) made of an austenitic steel is used which has a chromium content of 15 to 17 wt. %, a manganese content of 12 to 16 wt. % and a molybdenum content of 0 to 4 wt. %, and that the wire section (4) is formed with an oval cross-section having an ovality O in a range between 0.4 to 0.9, wherein the ovality O is dimensioned as a ratio between a length (LQk) of a small transverse axis (Qk) to a length (LQg) of a large transverse axis (Qg) of the cross-section.

Abstract: Flexible probing elements (4.1, . . . , 4.6) with different diameters are guided into an interdental space for determining a proximal allowance of the interdental space. The proximal allowance is determined according to the parameter values that correspond to the probing element that just barely fits through the interdental space. The probing elements (4.1, . . . , 4.6) can be realized on a probing tip (3) with a diameter that changes continuously or in a stepwise manner. The determination of the proximal allowance makes possible for an adviser to determine in an exact and reproducible manner the optimum interdental brush for the user.

Abstract: An interdental cleaning device having a clevis freely pivoted on one end of a shank. A brush carrier is detachably connected to and extends through the clevis and is engageable with a plurality of recesses formed on the end of the shank so that the clevis and associated brush carrier can be adjustably fixed at various angles to facilitate cleaning the interdental spaces from different sides of the oral cavity. A housing is provided which can be slidably mounted on the shank to provide either a handle for the device or a protective covering for the brush, carrier and clevis when not in use.
