Abstract
A method and apparatus is disclosed for treating teeth associated with tooth structure removal and disinfection, in particular for endodontic procedures such as root canal tissue removal and decay treatment. Traditional methods involve the use of files, reamers, chemicals, drills, and burs, which have many disadvantages. The disclosed method and apparatus are based on the use of micro-tornado forces generated in a small working head attached to a dental hand piece and discharged from an extended cannula into a root canal orifice or a cavity to abrade, cut, and remove the content.
