Abstract

Aim: The aim of this study was to evaluate the bond strengths of two different self-etch adhesive systems and an etch-and-rinse adhesive system to cervical enamel and dentin. Materials and Method: Sixty extracted non-carious human mandibular molars were mounted in self-curing acrylic resin and the cervical enamel surfaces were ground with a mechanical grinder to obtain flat surfaces. The teeth were randomly divided into three groups; while the two groups were treated with one and two-step self-etch systems (Clearfil SE Bond, AQ Bond), the other group was treated with a two-step etch-and-rinse adhesive system (Single Bond). After the bonding procedure, a plastic tube (3mmx3mm) parallel to the occlusal surfaces was attached to the enamel. The tube was filled with a universal hybrid composite resin and polymerized. After storage of specimens in water at 37 o C for 24 hours, shear bond strengths were measured with a Universal Testing Machine at a crosshead speed of lmm/min and enamel shear bond strength values were obtained. Then the cervical enamel surfaces were removed to obtain cervical dentin surfaces of the same teeth and flattened with 600 grit carbide paper. The same procedure was repeated to obtain dentin shear bond strength values. Statistical analysis was conducted with one and two-way ANOVA .Significance level was set at 0.05. «• Results: There was a statistically significant differen¬ce between the enamel bond strengths of an etch-and-rinse adhesive and self-etch adhesive systems (p0.05). While the bond strength of Single Bond to cervical enamel was significantly higher than to cervical dentin (p

Özet

Amaç: Bu çalışmanın amacı iki farklı self etch adeziv sistemle etch-and-rinse sistemin servikal mine ve dentine olan bağlanma dayanıklılığının incelenmesidir. Gereç ve Yöntem: Bu çalışmada 60 adet çürüksüz insan molar dişi akrilik rezin bloklara gömüldü ve servikal mine yüzeyleri mekanik bir aşındırıcı yardımıyla düzleştirildi. Dişler rastgele üç gruba ayrıldı ve iki gruba tek ve iki aşamalı self etch adeziv sistemler (AQ Bond, Clearfil SE Bond), diğer gruba ise iki aşamalı etch-and-rinse adeziv sistem (Single Bond) uygulandı. Adeziv uygulanan mine yüzeylerine 3 mm çapında ve 3 mm yüksekliğinde hazırlanan plastik tüpler, dişin okluzal yüzeyine paralel olacak biçimde tutularak içerisine mikrohibrit kompozit rezin uygulandı ve ışıkla polimerize edildi. 37oC'de 24 saat süre ile distile suda bekletilen dişlerin kompozit rezin-diş birleşim bölgelerine Universal Test Cihazında lmm/dak kafa hızında yük uygulanarak, mineye olan bağlanmanın kesme tipi kuvvete karşı dayanıklılık değerleri saptandı. Daha sonra aynı dişlerin servikal mine yüzeyleri dentin dokusu açığa çıkıncaya kadar aşındırıldı ve dentin yüzeyi 600-gritlik zımparayla düzleştirildi. Adezivlerin servikal dentine olan bağlanma dayanıklılığı aynı yöntemle ölçüldü. Elde edilen bağlanma dayanıklılık değerleri tek ve iki yönlü varyans analizi (ANOVA) ileistatiktiksel olarak değerlendirildi . Önemlilik düzeyi 0.05 olarak alındı. Bulgular: Etch-and-rinse adeziv sistem (Single Bond) ile self-etch adeziv sistemlerin (Clearfil SE Bond ve AQ Bond) servikal mineye olan bağlanma dayanıklılık değerleri arasındaki fark istatistiksel olarak anlamlı bulunurken (p0.05). Single Bond'un servikal mineye olan bağlanma değerinin servikal dentine oranla daha yüksek olduğu (p0.05). Sonuç: Adeziv sistemlerin bağlanma dayanıklılığı adeziv sistemlerin farklılığı kadar bağlanma yüzeyindeki yapısal ve bölgesel farklılıklardan da etkilenmektedir.
