An interdental cleaner has a rod-shaped support, which is made of plastic and, in one end region thereof, is provided with a cleaning part made of a flexible plastic, and a handle part made of plastic. The support, at a support end facing the handle part, is integrally connected to the handle part in a connection region via a web. The connection region is configured as a joint, and the web is provided at least partially with a sheath made of a flexible plastic. Provision is made here that the web has at least one protruding web rib, and/or that at least one rib is formed on the outer face of the sheath.

One or more methods for sampling gingival metabolites and biomarkers.

Disclosed herein are systems and methods for providing personalized oral irrigation. One variation of a method of generating a model of an oral insert including a fluid inlet port, fluid nozzles, manifolds, and a tray configured to retain teeth 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, 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.

An interdental brush comprising an interdental brush bar and a grip, the interdental brush bar having a central shaft and a joint portion, the central shaft surface axially staggering a plurality of first bristle sets and a plurality of second bristle sets, the first bristle set has two first bristles, and the second bristle set has two second bristles, and each of the first bristles is connected with an adjacent second bristles to form a squeegee. The grip connects the joint portion, and the squeegee can increase the contact area with the teeth to enhance the cleaning effect.

A multiple purpose oral care device is provided. The device comprises a two-ended manual tool with ergonomically shaped handle and attachment components located at least at a first end to accommodate semi-circular snap-on flossers. The device also comprises disposable implements for dental and gum care that attach to the snap-on flossers and comprise optional structures. The disposable implements comprise at least one of brushes and gum stimulators and are situated at ends of the snap-on flossers. A first optional structure combines a snap-on flosser and two parallel inter-proximal brushes, one on each end of the flosser. The first optional structure is directed to orthodontic patients with braces and patients with fixed restorations comprising at least one of crowns and bridges. A second optional structure comprises two gum stimulators, one with each attached on opposite sides of the snap-on flosser, pointing inward to each other and parallel to floss.

An oral hygiene device, in particular a toothbrush, includes at least one application unit and includes at least one handle unit which is connected to the application unit and which has at least one material volume body, wherein the handle unit includes at least one essential hollow-space structure, which is at least substantially delimited by the material volume body and which extends at least over a substantial portion of a main extent of the at least one handle unit.

An all-in-one oral care system that includes a brush, a main body, a top cover, a bottom cover, an interdental brush, and a toothpaste cartridge. All major components are designed to be detachable and replaceable using attachment mechanisms built into each part. The oral care system utilizes a manual actuator to force toothpaste from the main body into the toothbrush head and onto the bristles when depressed. When released, the actuator creates a vacuum force that draws toothpaste from the cartridge into the main body. The vacuum force draws a plunger in the cartridge upwards to move the toothpaste to the main body.

An index plate molding device configured to produce a multi-component part including an injection mold having an injection parting surface, and an ejection mold having an ejection parting surface in selective contact with the injection parting surface to form an ejection parting line therebetween. The index plate molding device also includes an index plate movable relative to the injection mold and the ejection mold, where the index plate includes an index parting surface in selective contact with the injection parting surface to form an index parting line therebetween, and where the index plate is shaped such that the outer surface of the first component of the multi-component part is available for overmolding on both sides of the index parting line when the first component is coupled to the index plate.

An interdental cleaning tool capable of reducing possibility of a cleaning portion being detached from a shaft portion includes a base portion including a shaft portion (20) having a shape insertable in an interdental space, and a cleaning portion (50) that covers at least a portion of the shaft portion and is capable of cleaning an interdental space. The base portion further includes a protruding portion (40) that protrudes from a covered portion (22) in a direction intersecting the shaft portion (20), the covered portion (22) being a portion of the shaft portion (20) and covered by the cleaning portion (50).

An interdental cleaner (10) has a rod-shaped support (11) made of plastic, a handle part (12) connected to the support (11), and a cleaning part (13) which has a sleeve-shaped cover (14) arranged on the support (11). The cover carries radially outwardly protruding cleaning elements (15). Provision is made that the cover consists of a plurality of cover parts, wherein a first cover part (16) consists of a first soft-elastic plastic, and wherein a second cover part (17) consists of a second soft-elastic plastic or of a thermoplastic, wherein the plastics material of the first cover part (16) is different than the plastics material of the second cover part (17). Preferably, the plastics material of the first cover part (16) has a lower Shore hardness than the plastics material of the second cover part (17).
