ABSTRACT:
A composition for detecting normally invisible cracks and splits in teeth, both in situ or in vitro. A detector solution contains a dye adapted to selectively stain such cracks and splits, advantageously methyl violet, a small amount of a surfactant, preferably dioctyl sodium sulfosuccinate, and a small amount of an acid, preferably glacial acetic acid, the remainder essentially water. A kit provides a holder or container and, at least one bottle containing such detector solution and one bottle containing a solvent for removing detector solution after the completion of the test. A preferred kit provides, in addition to the dye-removing solvent, two bottles, one containing solvent and dye, the other one containing solvent, surfactant, and acid, and equal amounts from each of these two bottles are mixed just before use on a patient. A method of selectively staining and detecting normally invisible cracks and splits is also provided.
