Abstract (2. Language): 
The degree of stress development during the setting of the composite material can be controlled to some extent, by the flowable composite lining materials and by the cavity design. The purpose of the present work was to investigate a possible relationship between the thickness of a resin lining material and tensile bond strengths. Cavity configuration factor (C Factor) was also evaluated. Class II slot cavity praparations with two different cavity configurations were prepared on the proximal surfaces of caries free third molar teeth and restored with two different filling techniques. The thickness of lining cement was measured and the samples were tested under tensile stress loading. No relation was found between the thickness of lining material and tensile bond strengths. No statistical significant difference was also found between the groups due to cavity configuration and filling techniques (P>0.05). The elasticity of the resin lining material had an effect to get these results.

Abstract (Original Language): 
Kompozît materyallerin polimerizasyonları sırasında oluşabilecek polimerizasyon büzülme stresleri, ara rezin kompozit \bonding) materyaller ve kavite şeklinin değiştirilmesi ile azaltılabilir. B u çalışmada ara rezin kompozit materyal kalınlığı ve gerilim direnci arasındaki ilişki olasılığı araştırılmış ve ayrıca kavite şekli faktörü de değerlendirilmiştir. Molar dişlerin aproksimal yüzlerinde iki değişik derinlikte açılan Black II kaviteler, iki farklı teknikle restore edilmiş ve gerilim stresleri karşısında gingival duvarda bağlanma dayanımları değerlendirilmiştir. İstatistiksel a¬ nalizler sonucunda kavite şekli faktörünün bağlanma direncine etkisi olmadığı ve ara rezin örtücü materyal kalınlığının bağlanma dayanımı ile ilişkisi olmadığı gözlenmiştir. B u sonuçların alınmasında, ara rezin kavite örtücü materyalin elastik bariyer olarak etkisi olduğu sanılmaktadır. S E M sonuçlarına göre en fazla kırılmanın ara rezin kavite örtücü materyal içinde olmasının ise materyalin aşın kalınlıkta kullanımından kaçınılması gerektiği sonucunu vermektedir.
