§16§"Less is More"- Recent advances for endodontic canal preparations have focused on this concept of Single File Systems. According to the single file concept one single file is able to transition a secured canal to a well-shaped canal. Single file endodontic concept is said to require only one file for complete instrumentation for majority of root canals. The technique is supposed to reduce the working time and lower cross contamination between patients, a common problem associated with the use of multiple files. Use of a single file will be very attractive both in terms of time and cost saving.
