The aim of the study was to evaluate the effectiveness of the Endovac irrigation system
regarding 1) debris removal and 2) the control of apically extruded irrigating solution.
Materials and Methods:
Fifty extracted human single-rooted teeth were used in this study. Teeth were then randomly
divided into three experimental groups according to the type of irrigation technique used and
one control group. In group 1 (n=15), irrigation was performed with Endovac irrigation system.
In group 2 (n=15), irrigation was performed with a 30 gauge tip-vented irrigation needle. In
group 3 (n=15), irrigation was performed with a 30 gauge side-vented irrigation needle. The
control group (n=5) received instrumentation with no irrigation serving as controls for the
cleaning efficiency. Root canal instrumentation was performed by using the Profile NiTi rotary
system in a crown-down technique. All experimental teeth were irrigated with the same amount
of 5.25% sodium hypochlorite. The amount of extruded irrigating solution was then measured
by subtracting the post-instrumentation weight from the pre-instrumentation weight using the
electronic balance (Precisa 180A- Swiss made). The cleanliness of debris removal was
evaluated using the scanning electron microscopy.
Extrusion results showed that the group that resulted in more irrigation extrusion was as follows
from highest to lowest: tip-vented > side-vented > Endovac. The difference between all the
groups is highly significant (P = 0.000 < 0.05). As for the cleaning results, debris collection in
the both the EndoVac and tip-vented groups was least in the apical third. In both the control and
the side-vented groups, debris was most in the apical third. But this difference was not
significant between the three experimental groups.
In conclusion, the EndoVac irrigation system extruded significantly less irrigant solution than
both the needle irrigation systems. Debris collection was least in the apical third regarding the
EndoVac irrigation system. No significant difference was found in the cleaning efficiency between the three irrigation systems used.|
