Abstract: A dosing syringe has a cylindrical syringe body which at its tapering end has a dispensing orifice and at its other end a stepped cylindrical enlargement with two opposing handles. A recess is located below each handle, and a piston is inserted into the cylindrical syringe body. The piston is in contact with a dosing plunger having an external thread. Two threaded sides are arranged around the plunger and each threaded side has a positioning projection introduced into the recesses of the enlargement. According to the invention, the piston is connected to the dosing plunger by a spring retainer connection and the threaded sides have an outside groove in which an O-ring is inserted in countersunk fashion to hold the two threaded sides together. As a result, the piston-dosing unit can be prefabricated and introduced as a complete unit including the threaded sides into the enlargement of the syringe body where it is fixed simplifying the production technology of the dosing syringe.
Abstract: A container which can be easily filled and handled for the packing of two compositions which must be separately kept until mixed shortly before use, consists of two separate chambers which are arranged one upon the other in a packing unit. The upper chamber is provided with a closeable orifice for the delivery of the mixture. An intermediate part is arranged between the two chambers and such part has cutting edges or sharp mandrels on both sides thereof which allow the two compositions being separately kept to be mixed by cutting the bottom part of the upper chamber and the upper part of the bottom chamber when the container is pressed or screwed together.
Abstract: A composition for oral hygiene with efficacy against dental plaque contains as active substances a mixture of copper compounds and 2,4,4'-trichloro-2'-hydroxydiphenyl ether, preferably in an amount of from about 0.05 to about 1.5% by weight.
Abstract: A composition for oral hygiene with efficacy against dental plaque which contains a synergistic mixture of copper compounds and hexetidine, preferably in an amount of about 0.05 to about 1.5 % by weight, calculated based on the total composition.
Abstract: The present invention relates to a method for rounding the bristle tips of toothbrushes by the action of laser radiation, characterized in that the rounding process is effected in an electrostatic field, thus avoiding the fusion of the individual bristles as well as the formation of a mushroom-like bristle tip.
Abstract: Skin care composition containing mineral salts releasing sodium, potassium, megnesium, calcium and zinc salts in defined concentration, and, optionally, compounds releasing copper, manganese, vanadium, aluminum, cobalt and/or iron ions.

Abstract: A composition for oral hygiene with improved efficacy against dental plaque, said composition containing zinc aspartate and/or copper aspartate, preferably in an amount of 0.05 to 5% by weight based on the total weight of the composition.
Abstract: An electrically operated toothbrush comprises a housing with an electromotor inside the housing. The motor includes a rotatable shaft, means converting the rotary movement of the rotary shaft to an oscillatory movement of a brush support shaft which extends through the housing, and a toothbrush is attached to the free end of the support shaft outside of the housing. Sensing structure generates an impulse representative of the pressure exerted on the toothbrush during toothbrushing. A microprocessor or electronic device receives the impulses from the sensing structure during toothbrushing and compares those impulses with stored information representative of a predetermined optimum pressure range for toothbrushing. A signal transmittor releases a signal perceptible by the user of the toothbrush when the pressure on the toothbrush exceeds the predetermined optimum pressure range.
Abstract: Dental restoration materials with improved properties, particularly X-ray opacity and polishability, are obtained, if they contain fillers and polymerizable compounds consisting in total or in part of one or more compounds of the general formula ##STR1## where R represents H or a methyl group, X is representing a ##STR2## and n means 0 to 3.
Abstract: Dental filling material on the basis of polymerizable compounds and an inorganic filler mixture with improved properties, particularly excellent X-ray opacity and polishability, where the filler mixture essentially consists of an X-ray opaque filler with a particle size distribution of between 0,5 and 40 .mu.m, an X-ray opaque filler with a particle size distribution of between 0,2 and 15 .mu.m and a microfiller, particularly colloidal silica, with a particle size distribution of between 5 and 150 nm.
Abstract: A toothbrush having a brush handle and brush head is provided with a plurality of openings in the brush head for receiving therein bundles of bristles. Each of the plurality of openings is in the shape of a hexagon having parallel elongated sides and rounded opposing ends. The plurality of hexagonal openings are also of a substantially uniform depth to evenly receive the bristle bundles.
Abstract: The present invention relates to a method of binding particles, in particular dental filling materials, comprising incorporating into the materials at least one compound selected from the group of diacrylic and dimethacrylic acid esters of the general formula ##STR1## wherein R.sup.1 is a divalent araliphatic, cycloaliphatic or aromatic group having 2 to 18 carbon atoms; R.sup.2 is hydrogen or methyl; R.sup.3 is a --CH.dbd.CH-- or --(CH.sub.2).sub.n -- wherein n is 2 to 4, a substituted, unsubstituted or hydrogenated benzene group, cyclohexane, or cis-norbornene group and R.sup.4 is H or ##STR2## wherein R.sup.5 is n-butyl, isobutyl, hexyl, substituted or unsubstituted phenyl or cyclohexyl. Dental restoratives and filling materials are also disclosed.
Abstract: Tooth and mouth care preparations in the form of toothpaste, mouthwash, mouth spray or tooth powder, containing 0.05 to 2.5% by weight of hesperidin, calculated on the total composition are effective in reducing inflammation and bleeding of the gums.
Abstract: The invention relates to an electrically operated toothbrush with oscillating motion, whose angle of oscillation can be adjusted.This is a easily achieved by the fact that the rotation of the electric motor producing the motion can be reversed by pole changing, and thereby the radius of the circular orbit of the bolt of a rotating shaft connected to the holder taking up the slip-on brush in a curve-like opening of a free disc is changed in its dimension, thus producing a variation of the angular deflection of the rotating shaft.
Abstract: The invention is directed to a dispenser of the type used for providing mured amounts of a paste, such as a toothpaste or shaving cream. A cylinder having a dispensing mouth but otherwise closed at the top is mounted for sliding movement within a casing in the bottom of which is a coiled spring and from which a piston rod extends upwardly toward the said mouth. A piston is slidably mounted on the piston rod with walls adjacent the inner wall of the cylinder, with a reed spring clip supporting the said piston. When the cylinder is pressed downwardly against the spring, the piston cannot move because of the gripping action of the reed spring clip and a predetermined amount of material is ejected from the mouth. Upon release of the cylinder, it moves upwardly under the force of the spring for a predetermined distance, and by action of the spring clip moves the piston upwardly. The parts are then in position for the next dispensing action.

Abstract: A silver-tin-copper master alloy powder useful as a dental filling when amalgamated with mercury and having improved properties for that utility can be obtained by the steps of:(a) pulverizing an alloy containing silver, tin and copper into a first spherical powder by high pressure water, inert gas or similar pulverization(b) drying and forming said first powder into a coherent shaped article;(c) sintering the shaped article at an elevated temperature; and(d) pulverizing the sintered shaped article by machining into a master alloy powder.
Abstract: A container for holding a viscous liquid medium and from which the same may be selectively dispensed in a desired amount includes a rigid body having a deformable top portion and carrying a dispensing mouthpiece. The application of an inwardly-directed force to the mouthpiece deforms the container top portion and causes displacement of the mouthpiece partially into the container interior such that valve openings in the mouthpiece that are normally disposed sealingly within a valve body in the interior of the container are carried to a position remote from and clear of the valve body to clear the valve openings and permit a dispensing flow of liquid through the mouthpiece and thereby out of the container body.
