Abstract: The present invention relates to a composition comprising at least one biologically active protease and at least one biologically active glycosidase wherein the proteases and the glycosidases are present in an activity ratio of from 1,000,000:1 to 1:1,000,000 and wherein the composition has a total enzyme activity of at least 2 U/ml. Furthermore, the present invention relates to a process of producing such enzyme comprising composition and to processes of removing caries. Moreover, the invention relates to the use of one or more enzyme comprising compositions for producing a treatment agent for removing caries.

Abstract: The invention relates to a method for the determination of the patient-related risk of caries by determination of lactic acid and/or lactate in saliva and to a method for the location-specific determination of the patient-related risk of caries.

Abstract: The present invention relates to a composition comprising at least one biologically active protease and at least one biologically active glycosidase wherein the proteases and the glycosidases are present in an activity ratio of from 1,000,000:1 to 1:1,000,000 and wherein the composition has a total enzyme activity of at least 2 U/ml.

Abstract: The invention relates to deformable, curable or film-forming support materials which contain diagnostically useful additives for locus- and substance-specific intraoral diagnostics, and processes for the preparation of images for intraoral locus- and substance-specific diagnostic purposes, in which diagnostically useful additives are applied to deformable, curable or film-forming support materials containing no diagnostically useful additives, in such a quantity that a diagnostic signal can be observed, the diagnostic result being obtained without a cultivation step.

Abstract: The present invention relates to a composition comprising at least one biologically active protease and at least one biologically active glycosidase wherein the proteases and the glycosidases are present in an activity ratio of from 1,000,000:1 to 1:1,000,000 and wherein the composition has a total enzyme activity of at least 2 U/ml. Furthermore, the present invention relates to a process of producing such an enzyme comprising composition and to processes of removing caries. Moreover, the invention relates to the use of one or more enzyme comprising compositions for producing a treatment agent for removing caries.

Abstract: The invention concerns surface treatment agents for hard tissue, including at least one enzyme and an agent inhibiting the enzyme activity, whereby the surface treatment agent remains on the hard tissue during the application.

Abstract: Fine-grained powders or powder mixtures can be used to provide for spray cleaning of supragingival tooth surfaces. The abrasion of the tooth surface by the spraying of powder does not exceed 0.15 mm3 in relation to a tooth surface of 10 mm2 during a spray period lasting 2 minutes at a pressure of 4 bars and a distance of no more than 2.5 mm between the tooth surface and nozzle of the spray jet.
