Abstract:
Two units for root canal preparation operated in the sonic and ultrasonic range have been tested for their antibacterial action The Cavi-Endo-Unit (DeTrey/Dentsply) rendered the root canal absolutely sterile in less than 60s, while the Endo MM 3000 Sonic Air (Micro Mega) left the root canal with evident germs after as much as 5 min.
