A comparative SEM assessment for the ability of PIPS, XP-Finisher and PUI to eliminate smear layer and open dentinal tubules
Egyptian Dental Journal, 2022•edj.journals.ekb.eg
Aim: This study aimed to assess the removal of smear layer from the dentinal surfaces after
canal cleaning and irrigants activation with different systems (Conventional needle irrigation,
PUI, PIPS, XP-Finisher). Methodology: Seventy human single rooted maxillary incisors were
instrumented up to X5 (50/6) Protaper Next rotary system. The irrigation activation was
performed using either: PIPS, PUI, XP-Finisher, or conventional irrigation. Samples were cut
lengthwise, then examined under a scanning electron microscope. Data were analyzed with …

Aim
This study aimed to assess the removal of smear layer from the dentinal surfaces after canal cleaning and irrigants activation with different systems (Conventional needle irrigation, PUI, PIPS, XP-Finisher).
Methodology
Seventy human single rooted maxillary incisors were instrumented up to X5 (50/6) Protaper Next rotary system. The irrigation activation was performed using either: PIPS, PUI, XP-Finisher, or conventional irrigation. Samples were cut lengthwise, then examined under a scanning electron microscope. Data were analyzed with Kruskal- Wallis test. Significant difference between the groups was recorded statistically in the total scores of the smear layer on dentinal wall (P<0.05).
Results
PIPS and XP-Finisher groups showed more smear layer removal than the conventional and PUI groups and this was statistically significant (P<0.05). This was clearly presented by opened dentinal tubules in photomicrograph of SEM.
Conclusion
With the constraints of this in vitro study, PIPS and XP-Finisher are better in eliminating smear layer from dentinal walls.
