Rotating dental systems and related guards and methods are disclosed. In some embodiments a guard is configured to prevent material from building up on at least a portion of the dental system. In some embodiments the guard is configured to prevent materials from being discharged from the dental system. In some embodiments, the guard is configured to direct the flow of material along a portion of the dental system. Some guards within the scope of this disclosure include bristles.

The present invention is directed to a cosmetic applicator brush comprising a plurality of columns, and a shaft. The shaft comprises a plurality of opening parts around a circumference of the shaft, and the plurality of opening parts are spaced around the circumference in a radial direction of the shaft. Each of the plurality of columns comprises bristles or combs. Each of bristles or combs has a projecting part, which are inserted into the plurality of columns with an equal distance or different distances among them. A number of the plurality of opening parts around the circumference of the shaft is both even and odd number. The plurality of columns are inserted into the opening parts of the shaft irregularly to show the zigzag effect of the cosmetic applicator brush.

A three-in-one tooth-cleaning device structured as a toothpick, an interdental brush, and a floss pick includes a main body and an interdental elastic-bristle portion. The main body is integrally formed of a first plasticized material by injection molding and is structured as a floss pick at one end and as a toothpick at the opposite second end. The interdental elastic-bristle portion is integrally formed by injection molding a second plasticized material over the periphery of the main body in a section adjacent to the second end of the main body and forms a plurality of bristles. The second plasticized material has a lower hardness than the first plasticized material. The three-in-one tooth-cleaning device can be carried around to perform diversified, thorough, and effective removing operations on the dental plaque or food debris on and/or between teeth anytime and anywhere to prevent dental caries (especially interdental caries) and periodontal disease.

The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, an oral care agent dispenser device includes: (1) multiple chambers each configured to receive a cartridge containing a different oral care agent ingredient of a plurality of oral care agent ingredients; (2) memory configured to store an oral care agent formulation that includes one or more of the plurality of oral care agent ingredients; and (3) a dispenser positioned above an oral care agent dispensing region, the dispenser configured to dispense one or more of the plurality of oral care agent ingredients in accordance with the oral care agent formulation.

A brush assembly comprising a cushion pad and a plurality of brushes secured to the cushion pad. The cushion pad has a 25% compressibility within the range of 6.9 kPa (1 psi) to 2413 kPa (350 psi). At least one of the plurality of brushes comprises: a brush base, and bristles, the bristles comprising moldable polymeric material and abrasive particle additives.

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.

A personal-care applicator comprises at least one stem having a proximal end including a handle and a distal end opposite to the proximal end and at least one bristled component attached to the stem, wherein the bristled component comprises a carrier and a plurality of bristles ultrasonically welded to the carrier and outwardly extending therefrom according to a pre-determined pattern, wherein the elongated carrier and the at least first plurality of bristles comprise ultrasonically compatible materials, and wherein the bristles are ultrasonically bonded to the carrier through a direct ultrasonic bond between a surface of the carrier and a lengthwise portion of each of the bristles. Process comprises providing at least one elongated stem having a proximal end and a distal end, providing the at least one bristled component, and attaching the at least one bristled component to the at least first stem.

A disposable cleaning pad having a grout cleaning brush includes a bristle attachment for use with a disposable pad. The bristle attachment is molded into a rectangular base piece forming a stand-alone removable brush that can be removably attached to a disposable pad. A top rectangular piece of similar dimensions to the base is connected to the end portion of the base by way of a hinge. The ends opposite the hinge have mating clasps that allow for the brush assembly to be securely yet removably fastened to an existing cleaning pad which is then mounted in the normal manner to the cleaning system. The brush assembly enjoys a longer life than that expected from a disposable cleaning pad thus the brush assembly may be reused many times before it needs to be replaced.

The present invention relates to an device for applying a flowing or paste-like product to keratin fibers, comprising an elongate central core (1) extending along a longitudinal axis XX, at least one row of elongate bristles (2) comprising a first end (20) embedded on the core and a second, free end (21), the bristles (2) and the core (1) being made in one piece. According to the invention, at least one of bristles has a flattened shape in a plane substantially perpendicular to axis XX, said at least one bristle being defined in a front view by a first ridge (25) that is continuously convex or concave from the base (20) thereof embedded in the core (1) up to the second end (21), and by a second ridge (26) consecutively concave and convex from the base (20) thereof embedded in the core up to the second end (21), the first and second ridges meeting at the free end (21). The bristles have a slit (24) in the body thereof for defining a first (22) and a second (23) side flank arranged opposite one another. Two bristles consecutively rooted along the length of the applicator may form at least one distal opening (30) between one another.

An oral care implement that includes a handle and a head. The head may include a support structure and a monolithic cleaning unit coupled thereto. The monolithic cleaning unit may include a base portion coupled to the support structure and a plurality of bristles extending therefrom. At least one, or each, of the plurality of bristles may comprise a body having an outer surface and a rib extending from the outer surface. The rib may be longitudinally elongated in some embodiments and it may be helical in other embodiments. Furthermore, there may be more than one rib extending from the outer surface of the body. The monolithic cleaning unit may be formed of an elastomeric material.
