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.

Amaç: Bu in vitro çalışmanın
amacı, Biodentine® ve Imicrly
MTA'nın bir kompomer materyaline makaslama bağlanma dayanımını
karşılaştırmak ve farklı sertleşme sürelerinin bağlanma dayanımına olan etkisini
incelemektir.
Gereç
ve Yöntem:
Ortası delikli (4 mm çapında ve 2 mm yüksekliğinde) toplam 100 akrilik
blok hazırlandı. Akrilik bloklar uygulanacak siman tipine göre rastgele iki ana
gruba ayrıldı, Biodentine® veya Imicrly
MTA (n = 50). Daha
sonra, her bir ana grubun numuneleri, farklı sertleşme sürelerine göre rastgele
seçilen 5 alt gruba ayrıldı. (12 dakika, 24 saat, 48 saat, 72 saat ve 96 saat)
(n = 10). Numuneler, üreticinin
talimatlarına göre tamamen Biodentine® veya Imicrly MTA ile dolduruldu. Kompomer materyali
şeffaf tüp yardımıyla yerleştirildi ve kompomer LED cihazıyla (EliparTM, 3M
ESPE, MN, ABD) 40 saniye ışıkla polimerize edildi. Akrilik kalıplar universal
bir test makinesine sabitlendi ve kesme kuvveti 1 mm/dakika çapraz hızda olacak
şekilde makaslama bağlanma dayanım (MBD) testi yapıldı. Veriler iki yönlü ANOVA
ve Tukey's post-hoc testi ile analiz edildi (p = 0.05).
Bulgular: Biodentine®'in 12 dk sertleşme süresinde Imicrly MTA'ya göre MBD
değerlerinde anlamlı derecede yüksek iken (p
<0.05) diğer ayar dönemleri arasında Biodentine® ile MTA arasında anlamlı fark
yoktu (p> 0.05). Test edilen simanlardan
bağımsız olarak, sertleşme süreleri grupları arasındaki çift karşılaştırmalarda
benzer MBD değerleri vardı (p> 0.05).
Sonuçlar: Tüm sertleşme zamanı
gruplarında, Biodentine®'in kompomere olan bağlanma dayanım değerleri Imicrly MTA'ya göre daha
yüksek görülürken, yalnızca istatistiksel anlamlılık 12 dakika sertleşme süresi
grubunda mevcuttu.
