Abstract: The invention relates to a preparation for chemical-mechanical treatment of caries by means of a caries-dissolving two-component liquid. One of the components is an active, caries dissolving component and the other a component which reduces the aggressiveness of the active component to mucous membranes. The active component is a chloride compound comprising active chlorine, i.e. chlorine having a charge state of +1, Cl(+1), which chloride has a somewhat lower reactivity than sodium hypochlorite and then also a somewhat reduced dissolving effect on the carious substance.

Abstract: A dental instrument is provided for removing caries attacked dentine in connection with chemical-mechanical treatment of caries by means of a caries-dissolving solution applied to the caries for loosening the caries tooth substance. The instrument comprises a tool head with a number of scraping edges or bristles for scraping away the loosened caries tooth substance. In the spacings formed therebetween drops of the gel solution used for the chemical-mechanical treatment can be carried (transported) up to the tooth treatment site. The instrument is power-driven in order to provide the tool head with a predetermined scraping motion.

Abstract: The present invention relates to a two-component preparation for chemical-mechanical treatment of caries. The inventive preparation consists of a two-components: a first component comprising active chlorine; and a second component comprising a non-acidic amine, a gelling agent such as carboxymethylcellulose, and a dye agent, such as erythrosin, that interacts with carious material.

Abstract: A prefabricated inlay (1) for restoring a tooth by application and fixation in a cavity prepared in the tooth and having essentially the same shape as the inlay part adapted for insertion, is provided with a pin (6) which projects from the inlay part not adapted for insertion and which is arranged to be received in an inlay holder. The whole inlay (1) is made of a material translucent to light that is suitable for curing a light-curing material used for fixing the inlay in the cavity. The inlay holder has a light source and a light guide having a tip (18) with a recess (19) for receiving the pin (6) of the inlay (1), such that the light generated by the light source can be guided through the light guide and the inlay (1) to the light-curing material.

Abstract: An apparatus for separating solid particles, particularly mercury compounds and alloys, from a fluid, such as dental waste water, contaminated therewith, comprising a rotatable container to receive contaminated fluid, said container having a vertical peripheral wall and an upper horizontal wall depending from the outer periphery thereof to collect particles centrifugally urged thereagainst owing to the rotation of said container, and means at the lower part of said rotatable container communicating with a collecting means for recovering a mixture of fluid and particles having been collected at the peripheral part of said container. When the container ceases to rotate, the particles held at the periphery of the vessel are caused to pass gravitationally into a vessel communicating with the container.

Abstract: The invention relates to an apparatus for cleaning and/or disinfecting especially so-called handpieces in a dentist's equipment. The improved apparatus comprises a vessel which is fillable with a suitable liquid or liquid mixture. Said vessel encompasses a rotatably disposed shaft extending through a channel serving as an outlet for the liquid or liquid mixture. There are further means for temporary driving connection with the shaft of the handpiece intended for cleaning and a source for producing a force which, firstly, serves to cause the liquid or liquid mixture, preferably under rotation, to flow out through the channel and then pass through the handpiece, and, secondly, imparts a rotary motion to the shaft, which via a driving connection is transmitted to all of the moving transmission parts of the handpiece.
