Purpose: to compare the debridement efficacy of EndoVac irrigation versus conventional needle irrigation.

N= 44 single canaled vital teeth set in 22 matched pairs

Inclusion criteria: vital teeth with single canal and completely formed apices planned for extraction Excluded:  Teeth with severe periodontitis or gross caries


  • One tooth from each matched pair received irrigation by using the EndoVac irrigation system (EndoVac group) and the other tooth received conventional needle irrigation by using a 30- gauge needle (conventional needle irrigation group).
  • The irrigation performed with 5.25% NaOCl and 15% (EDTA). Each tooth in each pair received an equal amount of time for irrigation. Five additional teeth were used for control.
  • The teeth in both groups were prepared using Profile rotary instruments in a crown down technique.
  • In the EndoVac group, suction tubing attached to the syringe tip removed the excess irrigant.
  • The teeth were extracted, fixed, and decalcified. Six histologic slides each 6 μm thick were made from sections at 1 and 3 mm from WL and stained.

Most highlighted Results:



Clinical significance:

 EndoVac group resulted in significantly less debris at 1 mm from WL level compared with the conventional needle irrigation group.
