Single-File Technique Series The introduction of nickel-titanium (NiTi) rotary file systems has resulted in a markedly progress on the mechanical preparation of the root canal space. NiTi instruments offer many advantages over conventional stainless steel files such as flexibility and cutting efficiency. Furthermore, NiTi instruments maintain the original canal shape during preparation and have reduced tendency to transport the apical foramen. However, the current technology for mechanical preparation - rotary NiTi files - have failed in debriding oval-shaped canals, leaving untouched fins or recesses on the buccal and/or lingual extensions. This untouched recesses may harbor unaffected residual bacterial biofilms and serve as a potential cause of persistent infection and poor treatment outcome. Besides, as these techniques also require the use of numerous instruments to enlarge the canal to an adequate size and taper, they are relatively time and cost consuming. The newly developed rec...

"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...
