Description

Lack zur Verwendung bei Silikatzementen. Bekanntlich enthalten alle Silikatzemente einen Bestandteil, der das Absterben der Pulpa bewirkt; wahrscheinlich ist es die Zementsäure. Man hat schon verschiedentlich versucht, die Wirkung des schädlichen Bestandteiles dadurch zu beseitigen, daß man einfache Harzlacke und ähnliche Stoffe verwendet, d. h. den ausgebohrten Zahn vor der Füllung mit dem Silikatzement mit diesem Stoff auslackiert oder auskleidet.Varnish for use with silicate cements. It is well known that all contain Silicate cement, an ingredient that causes pulp to die; probably it is the cement acid. Attempts have been made on various occasions to demonstrate the effect of the to eliminate harmful constituent by using simple resin varnishes and similar substances are used, d. H. the drilled tooth before filling with the silicate cement lacquered or lined with this material.

Es hat sich aber ;gezeigt, daß diese Lacke usw. die schädigende Wirkung nicht verhindern und daß sie auch die Phosphorsäure der Süikatzementfüllung durchlassen, die dann schließlich an die Pulpa gelangen.But it has been shown that these lacquers etc. have the damaging effect not prevent and that they also let the phosphoric acid of the sulphate cement filling through, which then finally reach the pulp.

Gegenstand der Erfindung ist nun ein Lack, der das Hindurchtreten der schädlichen, in den Füllungen enthaltenen Stoffe verhindert und der das Protoplasma und insbesondere den Nerv schützt.The invention now relates to a paint that allows passage of the harmful substances contained in the fillings and prevents the protoplasm and especially protects the nerve.

Die Erfindung besteht darin, daB dem Lack anhydrophyle Stoffe für sich oder in Lösungen zugesetzt werden. Als besonders geeignet haben sich Vaseline und Paraffin erwiesen. Der Zusatz muB so gewählt werden, daß die Verwendbarkeit des Lackes in keiner Weise beeinträchtigt wird.The invention consists in the fact that the paint has anhydrophilic substances for be added to themselves or in solutions. Vaseline have proven to be particularly suitable and paraffin proved. The addition must be chosen so that the usability of the paint is not affected in any way.

Beispielsweise kann ein Lack benutzt werden, der aus einer 4prozentigen Celluloseacetatlösung in Chloroform mit Vaselinezusatz besteht.For example, a varnish can be used that consists of a 4 percent Cellulose acetate solution in chloroform with added petroleum jelly.
