The present invention is directed to a debridement and/or implant cleaning tool (1) in which the means for cleaning (4) is made of a biodegradable material. Thus, if parts of the means for cleaning (4) come loose during use, these will be degraded by natural processes in the body and will not remain in the body and cause negative body reactions.

Provided are multifunctional cases, device and kits for storing, peeling and cutting a miswak twig. Generally, the multifunctional case comprises a case portion and a cap portion each of which may have one or more compartments therein. The case is configured to store one or more miswak twigs therein and to contain an optionally removable clipper for cutting the twigs. The cap portion contains an optionally removable peeler and may further comprise a storage compartment and/or a cluster of bristling picks. The case may also comprise a mechanism to advance and to retract a miswak twig. The kits provided comprise any of the multifunctional cases or devices described herein and one or more miswak twigs stored within the case or device.

An oral care implement including at least one spiral bristle. In one aspect, the invention can be an oral care implement having a handle; a head coupled to the handle; at least one bristle tuft extending from the head, the at least one bristle tuft comprising at least one spiral bristle comprising coextruded first and second strand components that are intertwined together to form the at least one spiral bristle; the first strand component comprising a first plastic and a first oral care additive; and the second strand component comprising a second plastic and a second oral care additive, Tine rein the first oral care additive is different than the second oral care additive.

An electric toothbrush device with a built-in shrapnel assembly includes a toothbrush head, a brush assembly and an electric motor. A built-in shrapnel assembly is disposed in the cavity, and the built-in shrapnel assembly is disposed to abut against the drive shaft. The built-in shrapnel assembly includes an arch-shaped protrusion arching towards the drive shaft. A side of the drive shaft facing the arch-shaped shrapnel assembly defines a tooth groove matching the arch-shaped protrusion, the drive shaft presses against the arch-shaped protrusion, to cause the arch-shaped protrusion to undergo an elastic deformation, to thereby securely fix the drive shaft in the cavity. The electric toothbrush head device has the advantages of strong practicality, high stability, and long-term use without deformation, by providing the shrapnel assembly inside to increase the clamping effect.

A toothbrush head having a bristle support head with a plurality of miswak or miswak extract or neem or neem extract bristle tufts embedded in the bristle support head, surrounded by a plurality of synthetic bristle tufts embedded in the bristle support head, the plurality all of the bristle tufts together providing the mechanical efficacy of synthetic bristle tufts, while also providing the chemical benefits of miswak or miswak extract or neem or neem extract bristle tufts, thereby improving gingival health, salivation, and antimicrobial activity, while avoiding harmful wear on gingival tissue and occlusal damage to teeth. Also, a toothbrush head having a bristle support head with a plurality of miswak extract or neem extract bristle tufts embedded in the bristle support head, the plurality of extract bristle tufts together providing the mechanical efficacy of synthetic bristle tufts while also providing the chemical benefits of miswak extract or neem extract.
