Abstract
A dental instrument is provided for removing caries attacked dentine in connection with chemical-mechanical treatment of caries by means of a caries-dissolving solution applied to the caries for loosening the caries tooth substance. The instrument comprises a tool head with a number of scraping edges or bristles for scraping away the loosened caries tooth substance. In the spacings formed therebetween drops of the gel solution used for the chemical-mechanical treatment can be carried (transported) up to the tooth treatment site. The instrument is power-driven in order to provide the tool head with a predetermined scraping motion.
