The paralleling technique does not meet the shadow-casting principle that requires placement of the image receptor close to the teeth of interest
Indicate whether the statement is true or false
TRUE
Explanation: Parallelism is accomplished by using an image receptor positioner or film holder specifically designed to allow the patient to stabilize the image receptor in this position away from the crowns of the teeth. This position, however, does not meet the shadow-casting principle that states that the image receptor (film, phosphor plate, or digital sensor) and the object (tooth) should be as close to each other as possible.
