title: The radiographic platform: a new method to evaluate root canal preparation in vitro.
abstract: An in vitro method for evaluating root canal preparation in curved canals is presented. Based on Schneider's method, this technique makes it possible to obtain the position of the instrument before and after instrumentation in the same X-ray film. The use of the radiographic platform is a valuable research and teaching aid.
