Indicate whether the statement is true or false
TRUE
Explanation: The initial radiograph is exposed to determine the preoperative condition and to make a diagnosis. Additional radiographs are made as the work progresses to determine the length of the root; the position of a reamer, broach, or file in the canal; or the position of the sealer and point or points (the tooth may have several canals). Finally, a posttreatment radiograph is needed to ensure that the canal or canals are closed satisfactorily.
