THE CHALLENGE OF MDP MONOMER CONTAINING ADHESIVE SYSTEMS: COMPARISON OF SHEAR BOND STRENGTHS

Abstract

Aim: The aim of this in vitro study was to evaluate the shear bond strengths’ of three MDP monomer containing self-etch adhesive systems. Material and method: Sixty human third molars were used for the study. The teeth were sectioned with a low-speed diamond disk saw under water coolant to expose mid-coronal dentin. The teeth were randomly divided into three groups( n=20). The restorations (2.30mm diameter and 3mm heigh) builded with using three different MDP containing adhesive systems by aid of Ultradent Bonding Jig. After that, the specimens were placed in a universal testing machine and the shear bond strength was measured at a crosshead speed of 1 mm/min. Result: Group 1 and 2 showed significantly higher bond strength than group 3(p<0.05). There were no significant difference in bond strength values between group 1 and 2(p>0.05) in spite of group 1 showed slightly higher bond strength values than group 2. Conclusion: Within the limitations of this in-vitro study, all groups showed optimal results but first and second adhesives showed significantly higher values than third group

MDP MONOMER ĠÇEREN ADEZĠV SĠSTEMLERĠN REKABETĠ: MAKASLAMA BAĞ DAYANIMLARININ KARŞILAŞTIRILMASI

Abstract

Amaç: Bu in-vitro çalışmanın amacı MDP monomeri içeren üç farklı self-etch adeziv sistemin makaslama bağ dayanımınlarını değerlendirmektir.

Materyal ve Metod: Bu çalışma için atmış adet çekilmiş insan üçüncü molar dişleri kullanlmıştır. Dişler bir elmas kesme diski yardımıyla ve su soğutması altında kron boylarının orta üçlülerine kadar kesilmiştir. Kesilen dişler rastgele üç gruba ayrılmıştır (n=20). Ultradent Bonding Jig yardımıyla ve üç farklı MDP içeren self-etch adeziv sistem kullanılarak restorasyonlar yapılmıştır (2,30 mm çap ve 3mm yükseklik). Sonrasında örnekler test cihazına alınmış ve makaslama bağlanma değerleri ölçülmüştür.

Bulgular: 1. Ve 2. Grup restorasyonlar, 3. Gruba göre anlamlı derecede daha yüksek makaslama bağ değeri gösterdi. (p>0.05). Bunun yanında 1. Grubun 2. Gruba göre nispeten daha yüksek bağ değeri gösterdiği saptandı.

Sonuç: Bu in-vitro çalışmanın sonuçlarına göre, bütün grupların optimal bağ değerlerigösterdiği saptandı. Ancak 1. ve 2. Gruplar 3. Gruba oranla anlamlı derecede daha iyi bağlanma değerleri gösterdi.
