The invention relates to a dental instrument having electrical and pneumatic control elements which can be adjusted by rotation of an operating element. In order to simplify, inter alia, servicing and operation it is proposed that a common operating element (9) be provided for both control elements (5, 13), which includes carrier elements (10, 11) for transmitting the rotary movement both to the electrical control element (13) and to the pneumatic control element (17). <IMAGE>
