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