To this end a small quantity of the salt (borax) is inserted in the pulj) 10 cavity, or rubbed on the pulp stumps. Also crystaline borax has been mixed with oflier materials, (such as acid of cloves) and inserted in the pulp cavity. Such treatment has the disadvantage that the consumption of the astringent salt is so rapid as to prevent subsequent decomposition of the pulp. Besides, the process is inoi^e tedious than that practiced according to the invention dis- Ib closed herein. According to my said invention, therefore, I employ for the astringent salt a suitable carrier, consisting of a porous, non-decomposable substance, as asbestos, or fossil meal, which is impregnated with a solution of the said salt. I then let the salt crystalize in the carrier, and remove therefrom more or less of the 20 water of crvstalization bv means of heat, whereby the salt is transformed into a form which is hard to dissolve and which will firmly adhere to the porous body. If now a piece of the substance so prepared is placed upon the tooth pulp, the supply of astringent salt will be sufficient to prevent decomposition of the tooth pulp, by reason of the fact that it will dissolve ver^^ slowly. If desired, other 25 antiseptics may l:)e added to increase the effect produced by the salt. To this end, the preparation produced by the method described is impregnated witli an essential oil, whereby the advantage is gained that the astringent salt will dis¬ solve more slowly by reason of being inclosed, so to speak, in the essential oil, while the preparation will still exercise its anticeptic properties.
