CLINICAL MEDICINE

Detailed explanation-1: -When a removable prosthesis is left in the mouth during exposure, an image of the appliance will appear superimposed over the teeth. Prior to radiographic procedures, ask the patient to take out all removable items from the mouth, such as retainers, partial dentures, complete dentures, and the like.

Detailed explanation-2: -A film holder : is a device that is used to position an intraoral film in the mouth and retain the film in position during exposure . Purpose of using film holder is : to eliminate patient’s hand exposure. when the patient has a broken arm.

Detailed explanation-3: -Primary Factors. The primary exposure technique factors the radiographer selects on the control panel are milliamperage, time of exposure, and kilovoltage peak (kVp). Depending on the type of control panel, milliamperage and exposure time may be selected separately or combined as one factor, milliamperage/second (mAs).

Detailed explanation-4: -Overexposed images will have a distinct lack of quantum mottle while appearing ‘saturated’ or in extreme cases ‘burnt out’ whereby anatomy is completely obliterated from the radiograph.
