A series of radiographs on the same tooth is needed to evaluate various stages of endodontic treatment
Indicate whether the statement is true or false
True. 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). And finally, a post-treatment radiograph is needed to make sure that the canal or canals are closed satisfactorily.
