ABSTRACT:
This patent discloses a dental control unit, such as a dental cart, having a housing with four side walls, a lid pivotally secured to one side wall and movable between an open position and a closed position. A plurality of knobs, gauges, buttons, etc. are provided along one side wall. A transparent shield is secured to the lid so that, with the lid in its closed position, the transparent shield overlies and covers the various control members. Conversely, the control members are accessible once the lid is opened. The lid provides an outer smooth surface which facilitates the cleaning and disinfecting of the dental cart after patient use. The shield can also be used with other dental control units, such as a front delivery system and a rear delivery system.
