OBJECTIVE: The aim of this study was to examine the effect of bonding agents under fissure sealants on bond strength and microleakage.

MATERIALS AND METHOD: A total of 210 freshly extracted noncarious human third molar teeth were used (105 teeth for shear bond strength and 105 teeth for microleakage assessment). The teeth were randomly assigned to 14 groups, with 15 teeth in each group. Fissurit FX was applied to the etched enamel in the control groups. In the experimental groups, the self-etch adhesives: Clearfil SE Bond, G Bond, Clearfil DC Bond and the total-etch adhesives: Prelude, Adper Single Bond and Optibond S were applied and light-cured followed by the subsequent application and light-curing of Fissurit FX. Shear bond strength was tested to failure in a universal testing machine with a 1 mm/min crosshead speed. The shear bond strength data was analyzed by using One Way ANOVA and Tukey HSD tests. Microleakage was evaluated by using a dye penetration method after mechanical loading and thermocycling. The microleakage data was analyzed by using the Kruskal-Wallis and Tamhane tests.

RESULTS: The microleakage of the Adper Single Bond Plus group was significantly less than that of the control group (p<0.05). However, the shear bond strength value of the Adper Single Bond Plus group was significantly less than that of the control group, again. The shear bond strength value of Clearfil SE Bond was significantly greater than that of the control group (p<0.05).

CONCLUSION: Clearfil SE Bond improved the shear bond strength, and Adper Single Bond Plus decreased the microleakage of the fissure sealant. An inverse relationship was found between the microleakage and the shear bond strength performances of Adper Single Bond Plus.

Fissür örtücünün altına uygulanan adezivlerin makaslama bağlanma kuvveti ve mikrosızıntıya etkisi

Öz

AMAÇ: Bu çalışmanın amacı fissür örtücünün altına adeziv
uygulamanın makaslama bağlanma kuvveti ve mikrosızıntıya
olan etksinin incelenmesidir.
GEREÇ VE YÖNTEM: Çalışmada 210 adet yeni çekilmiş çürüksüz
insan üçüncü molar dişi kullanıldı (105 adet diş
bağlanma dayanım testi için ve 105 adet diş mikrosızıntı
için). Dişler rastgele 14 gruba ayrıldı (n=15). Kontrol gruplarında
asitlenmiş mine yüzeylerine Fissurit FX uygulandı.
Diğer gruplarda asitlenmiş mine yüzeylerine
kendinden pürüzlendirmeli (self-etch) adezivler Clearfil SE
Bond, G Bond ve Clearfil DC Bond ve tam pürüzlendirme
(total-etch) ardından uygulanan Prelude, Adper Single
Bond ve Optibond S adezivleri uygulandı. Daha sonra Fissurit
FX uygulanarak polimerize edildi. Bağlanma dayanım
kuvvetinin değerlendirilmesinde üniversal test cihazı kullanıldı.
İstatistiksel değerlendirmede tek yönlü varyans
analizi ve Tukey çoklu karşılaştırma testi kullanıldı.
Mekanik ve termal yaşlandırmadan sonra mikrosızıntı
değerlendirmesi için boya penetrasyon yöntemi kullanıldı.
Veriler, Kruskal-Wallis ve Tamhane testleri ile istatistiksel
analize tabi tutuldu.
BULGULAR: Adper Single Bond Plus grubunun mikrosızıntı
değeri istatistiksel olarak kontrol grubundan düşük bulundu
(p < 0.05). Adper Single Bond grubunun makaslama
bağlanma değeri kontrol grubundan istatistiksel olarak,
yine düşük bulundu. Buna karşın, Clearfil SE bond
grubunun makaslama bağlanma dayanım değeri kontrol
grubundan istatistiksel olarak daha yüksek bulundu
(p < 0.05).
SONUÇ: Clearfil SE Bond, fissür örtücünün makaslama
bağlanma dayanımını arttırdı; Adper Single Bond Plus, fissür
örtücünün mikrosızıntısını azalttı. Adper Single Bond
Plus için bağlanma dayanım kuvveti ve mikrosızıntı
arasında ters bir ilişki olduğu görüldü.
