Self contained films are also available in size 2 (periapical). The envelope contains the film with a separate compartment with developer and fixer. Films are relatively expensive but good when radiographs are only taken occasionally. The films unfortunately do not keep unless they are fixed for longer as they otherwise discolour with age.

Each film has a '''raised dot''' in one corner. The dot helps with orientation when viewing and mounting dental radiographs if the following procedure is adhered to. Firstly, the dot should face the incident beam. Secondly, the film should be placed in the mouth so that the dot is always facing a specific direction. We advise that dot is positioned so that it is always facing forward in the mouth.

Ensure the correct side of the film envelope is facing the incident beam. The envelope is marked or labelled. If exposed through the back of the envelope, the lead sheet will absorb much of the X-ray beam, resulting in an underexposed radiograph with the pattern of the lead sheet imposed on it.
