Abstract: A medical film illuminator includes a frame having a translucent panel. A film gripper is attached directly to the translucent panel and the translucent panel is attached to the frame using magnets that engage the frame. Thus, the translucent panel can be easily removed to service the interior of the frame. Moreover, the spacing between the gripper and panel is established during manufacture and does not change, thus ensuring that gripping tension on film that is slid between the gripper and panel remains constant during the life of the illuminator.

Abstract: A camera cap for an intra oral camera includes a base plate from which a first side plate and a second side plate extend. The base plate forms a hole. The camera cap establishes an interior surface on which an adhesive layer is disposed. The camera cap can be installed on the head of an intra oral camera to block any light produced by the head of the camera while allowing imaging of, e.g., an x-ray, through the hole in the base plate.

Abstract: Color coding the components of a dental positioner, including an aiming ring, a bite block and an indicator arm allows the operator to assemble the correct positioner for proper positioning and alignment according to a particular dental area to be X-rayed. The color coding corresponds to different dental areas including the anterior and posterior dental areas. For coronal areas, a bite-wing block is provided which also may be in the color coded.

Abstract: A cassette for holding radiographic film in which the edges of the cassette are provided with identifying indicia in accordance with a preselected code. The cassette includes a rectangular front panel facing one side of the film and a removable back panel facing the opposite side. This latter panel is provided with a lead coating and a layer of felt on the surface adjacent the film. The back panel serves as a cover for the cassette and is held in place by a pair of leaf springs which are supported for pivotal movement intermediate their ends. A hollow rectangular frame is disposed about the periphery of the panels, and each edge of the frame includes an indentation in close proximity with but spaced from one of the adjacent corners of the frame. Each of the indentations carries coded identifying indicia mounted entirely within the indentation.
