Single-File Preparation
"Shape most root canals using only one file and decrease total shaping time..." I am sorry, but in cases like this one, the total shaping time should be increased to allow an adequate disinfection of the isthmuses that were not even touched by the instrument. Otherwise, most of the canal surface area will be kept without any treatment. With these images, it is possible to understanding the real influence of the root canal anatomy on the endodontic procedures. The root canal space is an arborizational, anastomotic, labyrinthine complexity, morphologically comparable to the pathways of a maze. While primary canals exist, the tributaries, accessory branches and lumina of the dentinal tubuli harbor extensive tissue and microflora. The existence of these vast, capacious passages has been demonstrated throughout the past century beginning with the work of Hess and continues to this day with the use of micro computed tomography. Presence of multiple foramina, additional canals...
