This study aimed to evaluate the effects of irrigation systems on
the bond strength of Biodentine, used as a pulp barrier in regenerative
endodontic treatment (RET), to the root canal dentin.
Following standardized preparation to obtain an immature tooth
model, a modified triple antibiotic paste (mTAP) consisting of
metronidazole, ciprofloxacin, and clindamycin was applied to the
root canals. Teeth were randomly divided into five groups according
to the irrigation system (n¼10): Group 1, Conventional
Syringe Irrigation (CSI); Group 2, Passive Ultrasonic Irrigation (PUI);
Group 3, EndoActivator (EA); Group 4, EndoVac (EV); and Group 5,
Nd:YAG laser (LSR). After removing the mTAP from the root
canals, parallel sections of 1mm thickness were obtained, with
three sections per tooth. Biodentine was applied to the obtained
sections, and a push-out test was performed. The data were
recorded in MPa, and images of the fracture types were examined.
There was no significant difference between the PUI and EV
groups (p>0.05), and their respective values, (4.43 ± 0.63) and
(4.37 ± 0.47), were greater than those of the other groups
(p<0.05). Although the push-out bond strength of the LSR group
was higher than those of the EA and CSI groups, there was no
difference between EA and CSI groups (p>0.05). The irrigation
system type had a significant effect on the push-out bond
strength of Biodentine to the root canal dentin in the RET. PUI
and EV groups had significantly higher bond strength values than
the other groups.
