A method for controlling a dental instrument includes a foot pedal responsive to commands from a user. An operating mode is selectable between normal and boost cycle. A conventional mode is selectable by pressing and holding the foot pedal to a first level to operate in normal mode. The foot pedal operates in a boost mode when the pedal advances to a second level. Maintained mode is selectable by tapping the foot pedal to change modes between idle, normal and boost mode. Each mode is switched by tapping the foot pedal. The pedal switches between the second process and the first process by pressing and holding the foot pedal at the desired level corresponding to normal or boost mode. The pedal switches from the first process to the second process by tapping the foot pedal at the level corresponding to normal or boost.

A positioning device for holding a dental x-ray imaging media during the taking of a dental x-ray includes an aiming ring, a bite block and a positioning arm extending therebetween. The bite block carries a journal or barrel for receiving a portion of the positioning arm therein such that the portion of the positioning arm thus received can rotate or move therein, such that the position between the bite block and the aiming ring can be selected in one of a plurality of positions corresponding to a position for taking one of a plurality of dental x-ray images. In another embodiment, the bite block carries a window through which a color-coded or other indicia portion of the positioning arm is positioned such that the user can view the indicia to determine the x-ray image for which the device is set.
