CLINICAL MEDICINE

Detailed explanation-1: -White Spots: These are also called as fixer spots on the film which is caused due to droplets of fixing solution coming in contact with an exposed film before it is developed.

Detailed explanation-2: -White areas are produced when virtually no x-rays were able to penetrate through the patient and interact with the film. Dense materials such as bone, iodine and lead produce areas of white on the x-ray film.

Detailed explanation-3: -Incorrect exposure can be caused by many factors; the most common being improper exposure settings. Improper time selection is the most likely error because most intraoral x-ray units have fixed or unchangeable milliamperage (mA) and kilovoltage (kVp) settings.

Detailed explanation-4: -For example, on typical radiographs, bones look white or light gray (radiopaque), whereas muscle and skin look black or dark gray, being mostly invisible (radiolucent).
