The invention relates to a retraction paste comprising a composition of i) 10 to 25% by weight at least one astringent compound, ii) 50 to 75% by weight fillers, iii) 10 to 35% by weight protic liquid, and iv) 0 to 10% by weight pigments, dye and/or rheology additive, ii) the fillers comprising kaolinite and mica in the ratio of 4:1 to 1.5:1 and, the total composition of components i) to iv) in the retraction paste amounting to 100% by weight, a method for producing the retraction paste, a kit comprising a container with the retraction paste for single or repeated use, as well as a retraction paste as an agent for haemostasis.

Retraction paste and container comprising the retraction paste

Dynamic mixers and methods have a chamber part with a discharge opening, a mixing chamber, a closing part, first and second inlet openings, and a centrical opening. The chamber and closing parts mount against each other in a rotationally symmetric manner and the closing part has substantially parallel planes, wherein a first plane averts a rotor, a second plane faces the rotor, a first inlet opening and a passage opening form a linear duct, and the substantially parallel planes form a feeding duct. Dimensions of the feeding duct are variable depending on a relative rotationally symmetric position of the chamber and closing parts, wherein the dimensions include a length, a width and/or height, and a partial circle is formable by the feeding duct and may enclose an angle of 20-170 degrees depending on the relative rotationally symmetric position of the chamber and closing parts.

Dynamic mixer having balanceable feeding ducts

A container () is provided for single- or multi-component molding materials. The container has a container body () having a constant outer contour in a longitudinal extent of the container (), a piston () movable in the longitudinal direction, and a cover () having an outlet opening (). A volume for a molding material is defined between the piston () and the cover (), the volume being variable in the direction of the longitudinal extent of the container (). The container distinguishes itself in that the container body () is rotatable relative to the outlet opening (), and the piston () thereby pushes out the content of the container ().

Multi-component mixing system having a rotatable container and container therefor

Single-use cartridges for the storing and dispensing of dental two-component impression materials have a closable external chamber with a cylinder-shaped external wall, a cylindrical closable internal chamber that is arranged coaxially or eccentric therein, a mixing element including housing and mobile mixer that is to be mounted separately or connected firmly to the external chamber at its inlet end. Either the internal cylindrical chamber is arranged such that it can be rotated and forms the drive shaft for the mobile mixer part of the mixing element, or the drive shaft extends parallel to the central axis through the internal cylindrical chamber or forms the central axis. The content of the chambers can be dispensed by means of conveying means whose axial thrust motions can be controlled independent of each other.

Temperature and/or irradiation and/or polymerization indicators comprise at least one 1,3-dipole and at least one dipolarophile, the dipole preferably being an ylide from the group of azomethines (sydnones), azomethinylides (munchnones), carbonylylides (isomunchnones), thiocarbonylylides (thioisomunchnones), or 1,3-dithiolylium-4-olates.

Temperature/irradiation/polymerization indicators

A self-curing or dual-curing, low viscosity composite is used for the fabrication of a dental liner capable of polymerization in 2 stages with 2 curing times and delayed polymerization characteristics that is designed for use at the cavity wall in the form of a thin layer.
