Date Jul. 9, 1998The invention relates to a dental instrument for removing carious dentine in connection with chemical-mechanical treatment of caries by means of a caries-dissolving solution applied to the caries for loosening the carious tissue. The instrument comprises at least one non-rotating tool-head (4, 5) for manually scraping away the loosened carious dental material. The tool head is star-shaped with a number of scraping edges (6) having a curved outer contour (periphery) for excavating loosened carious dental material in connection with said treatment method. The scraping edges (6) are designed to scrape in different directions, the bottom parts as well as the sides (peripheral parts) of a tooth cavity. The open spaces (9) formed between the scraping edges (6) admit transport by the instrument of drops of the solution used for the chemical-mechanical treatment method up to the carious tooth site.
