Figure 1-57. - Desk mount film viewer.
Figure 1-58 shows a serial mount for inter-proximal (bite-wing) radiographs. The mount contains slots for mounting five pairs of interpromixal radiographs for a patient taken at different times and mounted in chronological order. Serial mounting enables the dental officer to compare radiographs taken at different time intervals to detect changes in the patient's oral structures.
The front of the mount contains spaces for the patient's name and social security number, mount number, and the date of each exposure. Fill in this information whenever you start a new mount. After you have completed the necessary information on the front side, turn the mount over and lay it face down on a table top.
Place the radiographs on a flat, dry surface with the convex surface of the identifying "dimple" toward the observer. Pick up a radiograph by the edges. Hold it up to the, film viewer. The line representing the occlusal surface of the bicuspids and molars should gradually curve upward, forming one-half of a smile. If the line curves upward on the right, slide the radiograph into the right-hand slot on the back of the mount with the upward curve toward the outside of the mount. Keep the raised dimple facing you. If the line curves upward on the left, slide the radiograph into the left-hand slot. If both radiographs are mounted correctly, they will appear as shown in figure 1-58, forming a complete smile. Each time an additional pair of inter-proximal radiographs is mounted, enter the date on the line beneath the mounting slots.
