Provided is an interdental brush having a wire and filaments arranged therein by folding the wire and disposing the filaments between the wire and then twisting the wire. The interdental brush has improved filament retention and improved cleaning effectivity and reachability to minute portions. Each of filaments 3 has a polygonal cross section whose at least one corner portion has an interior angle 31 as acute as 30 to 75 degrees. Specifically, an angle θ3 of the acute corner portion 31 is set at 1.2 to 3 times a twisting angle θ4 of the wire. The filaments each have two or more such acute corner portions, and two or more rows of such filaments are disposed and laminated between the wire in a densely arranged manner.

The present disclosure relates to compositions and methods for cleaning and polishing dentures during denture fabrication. The stone cast used to make the denture is soaked in a dissolution composition bath for a period of time, which removes the stone cast. The denture is then polished with a solvent composition, where the solvent composition includes an active solvent with low solubility toward acrylics such as polymethyl methylacrylate (PMMA), and a carrier solvent with no solubility toward acrylics. As an alternative to the solvent composition, the denture can be recovered from the stone cast and polished with a device having a robotic arm, with a substrate having a pumice stone slurry.

ABSTRACT OF THE DISCLOSURE [Problem]Disclosed is a method for manufacturing a spherical brush having highly dense brush bristles for easy cleaning of periodontal pockets and a cylindrical brush having the brush bristles highly dense brush bristles at a ball portion of a tip thereof, and a brush manufactured by the manufacturing method. [Solution means]A fiber bundle, which is composed of a number of short fibers prepared by cutting long fibers, is gripped between a set of U-shaped wires arranged to crisscross with each other to form a loop. The open ends of the U-shaped wires are pulled and twisted in opposite directions, so that the fibers at the portion gripped by the U-shaped wires are compressed to reduce the size of their bundled areas. Elastic repulsion is established between the fiber bundles near a wire-gripped portion by the size differences of the cross sectional areas of the free end fibers at both ends of the wire-gripped portion, and is utilized so that the free end fibers diverge radially to the circumference from the wire-gripped portion.

Zahnreinigungsgerät mit einem Handgriff einem zum Handgriss relativ beweglichen Befestigungselement und einem Interdental-Behandlungsteil (30). In einem geschlossenen Zustand fixiert das Befestigungselement das Interdental-Behandlungsteil (30). Das Interdental-Behandlungsteil (30) weist einen Stiel (32) und einen, von dem Stiel (32) getragenen, Behandlungskopf(20) auf. Der Stiel (32) ist aus einem Draht (33) gefertigt. An einem dem Behandlungskopf (20) abgewandten Ende ist der Draht (33) derart gebogen, dass der Stiel (32) einen Abschnitt (36) aufweist, in welchem der Draht (33) zumindest doppelt geführt ist.

Das Reinigungsinstrument (10) umfasst einen Kopfabschnitt (12) und einen sich daran anschließenden Reinigungsabschnitt (14) mit einem Schaft (20), der an seiner Mantelfläche mit Borsten (22) versehen ist. Damit insbesondere der Zahnwurzelkanal oder auch ein Zahnzwischenraum mit dem Reinigungsinstrument (10) zuverlässig gereinigt werden kann, ist der Schaft (20) zusammen mit den Borsten (22) einstückig ausgebildet.
