Summary: | Objectives: The purposes of this in vitro study was to compare the bond strength of Biodentine® and Imicryl
MTA to a compomer material, and to examine the effect of the setting time on
the bond strength.
Materials
and Methods: A total of 100
acrylic blocks with a hole (4 mm in diameter and 2 mm in height) were prepared.
Acrylic blocks were randomly divided into two main groups according to cement
type to be applied, Biodontine® or Imicryl MTA (n = 50). The specimens of each main group were then divided into 5
subgroups, which were randomized relative to different setting times. (12
minutes, 24 hours, 48 hours, 72 hours, and 96 hours) (n = 10). The samples were filled completely with Biodentine® or Imicrly
MTA according to the manufacturer's instructions. Compomer was placed in this
transparent tube with the help of a hand plugger and light cured for 40 seconds
with the LED device (EliparTM, 3M ESPE, MN, USA) to polymerize the
compomer. The acrylic molds were fixed to a universal test machine and shear
bond strength (SBS) test was made under shear force at a cross-speed of 1
mm/min. Data were analyzed by a two-way ANOVA and Tukey’s post-hoc test
(p=0.05).
Results: While, Biodentine® had significantly higher SBS values than Imicrly MTA
at 12m setting time (p<0.05), there was no difference between Biodentine®
and Imicrly MTA among other setting periods (p>0.05). Regardless of cements
tested, there were similar SBS values among pairwise comparisons between
setting time groups (p>0.05).
Conclusions: There were higher SBS values of Biodentine® to compomer than Imicrly MTA
in all setting time groups, the only statistical significance existed in 12 min
group. Keywords:
