Provided is an interdental cleaning tool that can be smoothly inserted between back teeth. An interdental cleaning tool according to the present invention includes: a cleaning tool body that is made of a synthetic resin, and includes a grip portion that is capable of being gripped with fingers of a user and a shaft portion that extends in one direction from the grip portion; and a cleaning portion configured to clean between teeth, covering a leading end of the shaft portion, and made of an elastomer, wherein (angle b)/(angle a) is 0.82 or more, where the angle a is a rotational angle (degrees) when a torque value A is measured, the torque value A being a maximum torque value (N.Math.cm) when the grip portion is rotated at a rotational speed of 10 rpm about a position located 6 mm away from a leading end of the cleaning portion, and the angle b is a rotational angle (degrees) when a torque value B is measured, the torque value B being a maximum torque value (N.Math.cm) when the grip portion is rotated at a rotational speed of 10 rpm about a position located 10 mm away from the leading end of the cleaning portion.

An interdental brush realizing reuse of parts by a simple structure includes a shaft portion including an internal passage which extends in an axial direction and of which distal end and base end are opened; and a brush on which fibers are implanted over an entire area of a core that is longer than extension length of the internal passage. The shaft portion further includes a grip portion of which a state is changed between a gripping state for gripping the brush, which has been inserted into the internal passage from an opening on a base end side and of which a part protrudes from an opening on a distal end side, to restrict the brush from moving in the axial direction, and a releasing state for releasing gripping of the brush to allow the brush to move in the axial direction.

An apparatus for the interdiction of periodontal disease comprising a device the size of a US quarter coin capable of being chewed by a user, and which is configured with finger protrusions having fabricated blade ends capable of removing plaque from the teeth surface and disrupting plaque accumulated in the gingivae pockets of the teeth. The device of the apparatus is additionally configured with re-fillable inserts holding hygienic formulations to limit bacterial growth and flush plaque debris out of the gingivae pockets of the teeth. Some embodiments of the device of the apparatus are wholly digestible. The device of the apparatus is portable and comes in a plurality of embodiments in different shapes, all having the basic functionality of, self-treating periodontal disease.

Designing personalized oral irrigation may include a generated oral insert including a fluid inlet port, fluid nozzles, manifolds, and a tray configured to retain teeth. One variation of a design method may comprise the steps of displaying a graphical representation of the oral insert model, generating a geometry of the fluid nozzles based on oral scan data of a jaw, defining a tray surface that encloses the fluid nozzles based on the oral scan data, and generating a geometry of the manifolds that connect the fluid inlet port to the fluid nozzles on the graphical representation of the oral insert model. The manifolds are configured to provide a predetermined range of hydraulic pressures to each of the fluid nozzles.

A body care product, with at least one application unit and with at least one handle unit that is connected with the application unit and includes at least one material handle body, wherein the material handle body of the handle unit and/or the application unit are/is made at least partially of a paper material.

An interdental cleaning tool includes a base portion including a shaft portion having a shape insertable in an interdental space, a top end side cleaning portion including a top end side body covering a top end side portion of the shaft portion, and a plurality of top end side bristles protruding outward from an outer circumferential surface of the top end side body, and a base end side cleaning portion including a base end side body covering a portion of the shaft portion further in a base end side than the top end side body, and a plurality of base end side bristles protruding outward from an outer circumferential surface of the base end side body. The top end side cleaning portion has a lower hardness than the base end side cleaning portion.

Provided is an interdental cleaning tool that can reduce at least one of a resistance against insertion in an interdental space and a resistance against withdrawal from an interdental space, and has a high capability of scraping out deposit from an interdental space. The interdental cleaning tool includes a base portion including a shaft portion (20) and a cleaning portion (40). The cleaning portion (40) includes a cleaning portion body (50) and a plurality of bristles (60). The plurality of bristles (60) include at least one of a type of top end-oriented bristles and a type of base end-oriented bristles. The top end-oriented bristle has a shape titling to a top end side of the shaft portion (20) as advancing away from an outer circumferential surface of the cleaning portion body (50). The base end-oriented bristle has a shape tilting to a base end side of the shall portion (20) as advancing away from the outer circumferential surface of the cleaning portion body (50).

An interdental cleaner has a gripping portion (3) and a cleaning portion (4) formed by an elongate body made from a thermoplastic material. The cleaning portion (4) has a coating made of a self-adhesive, heat-vulcanized rubber material forming peripheral, flexible brush members (6).
