Every dentist/endodontist strives to consistently and completely remove bacteria from infected root canal systems, without causing too much damage to the tooth when doing an endodontic therapy. However numerous studies have shown that current chemo-mechanical methods of root canal preparation are not capable of completely cleansing the whole root canal system, whether by hand instrumentation or by motorized instruments. And many of those approaches do affect the remaining tooth structures, primarily by excessive removal of crown/root dentin.
It could be argued that the best way forward would be to have a system that does not require any instrumentation at all, but yet consistently leaves the canal system free of tissue, debris and bacteria. This idea is not new, thirty years ago a system was suggested that had the potential to achieve this and then more recently another system has been introduced.
This lecture will review the history of these two machines, critically review the available literature and reported outcome.
Describe the most recent attempts to achieve non-instrumentation disinfection of root canal systems.
Explain the technology that has been suggested with non-instrumentation approaches.
Describe the current literature that has investigated non-instrumentation approaches.
