Rotary instrumentation with NiTi has proven to be a valid and science-based modality, with many dental schools already incorporating the concept, into their predoctoral curriculum. Instrumentation is a highly significant aspect to root canal therapy whose importance has been stressed by many workers. Improved understanding of the mechanisms involved and greater appreciation of limitations of rotary instrument design currently available indicate that there is a continuing need for meticulous care and thoroughness in this stage of treatment. This explosive development of new technology in endodontic therapy, establishing its presence in the clinical domains of some of dentistry''s harshest skeptics, as well as innovative solutions to previously unanswered questions, will continue at an exponential rate well into the next millennium.The latest rotary instrumentations for performing endodontics have elevated the specialty to a level of sophistication never before attain. The future of endodontics looks bright, promising and exciting.
