| 總結: | Aim: To determine and compare the cleaning efficacy of two contemporary irrigation
systems with conventional irrigation needles using two different rotary NiTi systems.
Methods: 144 single rooted extracted human permanent teeth were divided randomly
into four groups: EndoVac irrigation system, NaviTip FX irrigation needle,
Conventional 25G needle and control. The groups were compared using TF and RaCe
rotary systems. Four-micron-thick serial sections were prepared at 1.5 and 3.5mm from
the apical foramen and the images were captured using optical microscopy and analyzed
using Mirax software. The statistical analysis was performed using Kruskal-Wallis Test
(p < 0.05) followed by intergroup comparison using Mann-Whitney Test (p < 0.008).
Results: While the cleaning ability of EndoVac irrigation system was significantly
better than conventional needle irrigation using both TF and RaCe rotary systems at 3.5
and 1.5mm (p < 0.008), there is no significant difference between NaviTip FX needle
and conventional needle irrigation at both levels. With the exception of the cleaning
ability at 1.5mm using TF, there is no significant difference between EndoVac system
and NaviTip FX needle (p > 0.008). At both levels, the cleaning ability of TF and RaCe
rotary systems with all irrigation systems was not significantly different.
Conclusions: EndoVac irrigation system has better cleaning ability than NaviTip FX
and conventional needle with both TF and RaCe rotary NiTi systems, especially at
1.5mm from the apical foramen. TF and RaCe rotary systems have similar cleaning
ability with all irrigations systems. |
