16.5.3 Developing the Ceph

When you are finished with all participants or when you are out of fresh cassettes, you must develop the x-rays and refill the cassettes. There are two primary film developers on the first floor of the dental school: 1. Radiology, near main waiting area and 2. The Orthodontic Clinic near the elevators

1. Enter darkroom and lock door behind you.
2. Turn on safety lights and turn off regular lights.
3. Open the first cassette and remove the film.
4. Gently feed the edge of the film into the receiving slot of the developer.

1. Once assured that the film is feeding properly, take the now-empty cassette and reload with a fresh film from the film box.
2. Repeat steps 3-5 until all cassettes are reloaded.
3. When last film is inside developer, and the film box is resealed, you can turn on the lights again.
4. Replace fresh cassettes in the film cabinet on “unexposed” side.
