  The present invention relates to a kit of parts for detection and removal of carious dentin tissue comprising: (i) one or more compounds being a hydrazine derivative, and (ii) means for chemical treatment of carious dentin tissue. Further, the invention concerns a preparation containing an active, caries-dissolving two-component liquid in the form of a first active, caries-dissolving component and a second component which reduces the aggressiveness of the active component to mucous membranes, a viscosity increasing substance and one or more compounds being a hydrazine derivative. The hydrazine derivative labels carious dentin tissue selectively and substantially irreversibly in the presence of healthy dentin tissue, which is useful in the context of caries removal.

  A technique is provided to visualize microtubules in live cells that does not require genetic manipulation or microinjection. Moreover, this method also avoids perturbation of the endogenous microtubule network that occurs with taxol treatment. This technique exploits tyrosination and detyrosination of tubulin, a posttranslational modification cycle specific to the C-terminus of α-tubulin. Specifically, cells are grown in medium supplemented with a tyrosine derivative possessing a reactive functional group. The cellular enzyme tubulin tyrosine ligase attaches the unnatural amino acid to a single site on tubulin. Addition of fresh medium containing a suitably derivatized fluorophore then yields fluorescent tubulin, which incorporate into cellular microtubules. Importantly, the tubulin labeling approach demonstrated here does not detrimentally affect microtubule network or cell morphology. Thus we present a simple, robust labeling technique that allows microscopic analysis of microtubules in live cells.

  The application relates to a method for testing a dental instrument comprising the steps of: a) subjecting healthy dentin tissue free from smear layer(s) to treatment with a dental instrument, thereby yielding treated dentin tissue, b) addition of a composition comprising one or more hydrazine derivative(s) to the treated dentin tissue obtained in step a), c) examining if the treated dentin tissue in step b) is stained by the one or more hydrazine derivative(s), and d) determining whether or not the treated dentin tissue contains a smear layer, wherein said one or more hydrazine derivatives is a compound of formula (I) RNHNH 2 wherein R is a chemical group containing a chromophore or forming a chromophore with NHNH 2 . Further, the application relates to a kit of parts for detection and removal of carious dentin tissue and to a method for detection and removal of carious dentin tissue.
