Abstract (2. Language):
This study was carried out with the aim of exam¬ining bond strength of belonging to different produc¬tive firms acrylic teeth and different denture resins and it was also carried out with the purpose of evaluating the effect of monomer application.
For this purpose, two different acrylic resin cen¬tral teeth depending to different firms were two used routinely in our clinic, and three different denture resin materials used in restoration (heat- cured, light- cured and autopolymerizing acrylic resins) were used. Monomer was applied to the half of total 60 central teeth, in equal number from both groups and it wasn't applied to the other half. 30 teeth to which monomer was applied, and 30 teeth to which monomer was not applied were divided into three groups equally.
Autopolymerized acrylic with 5 monomers and without 5 monomers was applied to some of teeth, and heat cured acrylic was applied to some of teeth, and light-cured composite was applied to some of teeth by divided them into three groups; and breaking off-force was applied with 130o angle in Hounsfield-pulling and pressing equipment.
The values obtained were evaluated with vari¬ance analysis. It was concluded that the type of repair¬ing material used was statistically significant
(p<0.001).
It was observed that bond strength was the high¬est in heat-cured acrylic and it was the least in light-cured composite. It was seen that the most bonding resistance was in the group applied to monomer in two groups and these two group teeth showed different bonding strenght.

Abstract (Original Language):
Farklı marka akrilik dişlere farklı restoratif materyallerin bağlanma kuvvetlerini incelemek ve monomer uygulamanın etkisini değerlendirmek amacı ile bu çalışma yapıldı.
Bu amaçla, kliniğimizde rutin olarak kullanılan iki ayrı firmaya ait iki farklı akrilik rezin santral diş ve restorasyon için üç farklı protez rezin materyali (ısı ile polimerize akrilik, otopolimerizan akrilik ve ışıkla polimerize kompozit rezin) kullanıldı. Toplam 60 santral dişin yarısına (her grupta eşit sayıda olacak şek¬ilde) monomer uygulandı, diğer yarısına uygulan¬madı). Dişlerin bir kısmına (5 monomerli, 5 monomer-siz diş) otopolimerizan akrilik, bir kısmına ısı ile polimerize akrilik ve bir kısmına da ışıkla sertleşen kompozit uygulandı. Daha sonra bağlanma kuvvetini tespit edebilmek için Haunsfield çekme- sıkıştırma cihazında 130o açı ile kuvvet uygulandı.
Elde edilen veriler varyans analizi ile değerlendirildi. Kullanılan tamir materyalinin ve monomer uygulamanın çok önemli (p<0.001), farklı diş grubunun ise önemli (p< 0.05) olduğu istatistiksel olarak saptandı. Bağlanma direncinin en fazla ısı ile sertleşen akrilik rezinde en az ışıkla sertleşen kom-pozitte olduğu görüldü).
