The Maximum Permissible Dose (MPS) for an occupationally exposed worker is the same as the general public.
Bulk film should be stored in low humidity, high temperature areas such as office treatment rooms.
A panoramic film is a good substitution for periapicals and bitewings.
An advantage of the paralleling technique, the film is placed away from the teeth but parallel to them.
Edentulous means the patient does not have teeth.
The fixer solution is the solution that contains silver from processing film.
The automatic or manual processor should have the chemicals replenished with a cup of developer and fixer once a week.
For best viewing, a film should be examined on a lighted viewbox.
The greater the distance of the cone from the face, the darker the film will appear.
When exposing bitewing film, the cone should be pointed down about 15-18 degrees.
Examples of intraoral film includes panoramic and cephalometric.
A vertical bitewing allows more bone to be seen than a horizontal bitewing.
Periapical films are the best type of film to determine impacted teeth and the presence of foreign bodies.
Overgloves are useful to prevent cross-contamination to the patient's lead apron and other surfaces.
As long as dental film is present in the patient's chart, there is no need to document exposing films in the treatment area.
Digital imaging uses a sensor rather than a conventional x-ray film.
Shorter wavelengths have less penetrating power and less energy than long wavelengths.
Wearing film badges to determine the amount of accumulated dosage of radiation is not a state requirement for the private dental office.
The position indicating device (PID) or cone is limited by law to 3 inches in diameter.
The penetration power of the x-ray machine is regulated by the kilo voltage (kVp).
Increasing the time on the dental x-ray machine will make the film appear darker.
