Purpose: to compare the efficacy of the EndoVac system and needle irrigation to debride the apical 3 mm of a root canal.
N= 21 matched pairs of root canals.
Inclusion criteria: intact, extracted human incisors, canines, and premolars ((with 1 canal or 2 distinct roots)
- The teeth were accessed and prepared using profile series 29 .04 taper rotary instruments in crown down technique.
- One tooth of each matched pair was irrigated by using the EndoVac system to working length. The other tooth of the matched pair was irrigated with a 30-gauge ProRinse irrigating needle.
- All teeth were irrigated with 5.25% NaOCl and 15% EDTA for the same amount of time, and total volume of irrigant used was recorded.
- Teeth were then fixed, decalcified, and sectioned at 1 mm and 3 mm from working length.
- Serial sections were made and digitally photographed. The amount of remaining debris was determined
Most highlighted Results:
- At the 1-mm level, significantly less debris was found in the EndoVac group (p 0.0347).
- At the 3-mm level, there was no significant difference between groups.
- Significantly more volume of irrigant was delivered with the EndoVac (p 0001).
Significantly better debridement can be achieved at 1 mm from working length by using the EndoVac compared with needle irrigation..
