Endodontic reboot: Adaptive core debridement and disinfective finishing
Fifty years ago, Dr Herbert B. Schilder introduced two legacy concepts to the science of endodontics: the constricted envelope of motion for instrumentation and the use of hydraulics to enhance the rheology of the obturation material used to seal the root canal space and optimize its gravitometrics. These were radical innovations for their time and despite technological and biological shortcomings of the armamentarium available, these innovations should have been technology iterated and shortcomings in material and manufacturing evolution obviated; however, until recently that has not proved to be the case in toto. In order to truly understand the inherent flaws, the clinician must recognise the totality of what is necessary to engender predictable clinical success in endodontics.
