Abstract

Root canal systems can present with multiple diversities. We have heard of working length which has been dealt with and researched in endodontic literature and routine clinical practice. Most of the regions along the root canal can be adequately debrided with conventional and rotary file systems and irrigating protocols. One of the first researches on apical working width was done by Dr. Yi - Tai Jou and colleagues who gave its definition as the initial and postinstrumentation width of the root canal system at working length and various other levels. This is especially important in the apical third of the canals which serves as a niche for the maximum amount of micro - organisms and is a challenge for effective cleaning and shaping.
