Özet
Amaç: İn vitro araştırmalarda dişler deneylerde kullanılacağı ana kadar dehidrate olmaması ve mikroorganizmaların ürememesi amacıyla, çeşitli saklama solüsyonlarında saklanmaktadır. Bu çalışmanın amacı çekilmiş dişleri saklamak için kullanılan üç farklı solüsyonun, mine yüzeyine uygulanan bir kompozit rezin dolgu maddesinin bağlanma dayanımı üzerine etkilerini araştırmaktır. Gereç ve Yöntem: Çalışmada 60 adet çürüksüz daimi molar diş çekimden hemen sonra 3 gruba ayrılarak % 0.1'lik timol, %10'luk formol, distile su içine konuldu. Saklama ortamlarında 24 saat bekletilen dişlerin bukkal mine yüzeylerine kompozit rezin dolgular (%36 fosforik asit, Prime&BondNTSpectrumTPH) yapıldı. Daha sonra dişler yeniden aynı saklama ortamına taşınarak 37C deki etüvde 24 saat bekletildi. Su soğutması altında düşük devirdeki elmas separe ile kesilen dişlerden, yaklaşık 1 mm2 lik bağlanma yüzeyine sahip çubuk şeklinde örnekler elde edildi. Örneklere lmm/dk hızda makaslama kuvveti uygulandı. Bulgular ve sonuçlar: Kompozit rezin dolguların mikro-makaslama kuvvetlerine karşı bağlanma dayanımları timol grubunda 7.352.28 MPa, formol grubunda 8.482.38 MPa, distile su grubunda ise 9.242.57 MPa olarak belirlendi. İstatistiksel değerlendirme sonucunda; timolde bekletilen dişlerin bağlanma dayanımının distile suda bekletilen dişlerden daha düşük olduğu (p0.05) bulundu. Formol solüsyonunda bekletilen dişler ile distile suda bekletilen dişlerin ve timolde bekletilenler ile formol solüsyonunda bekletilen dişlerin bağlanma dayanımları arasında ise istatistiksel olarak anlamlı fark olmadığı (p0.05) belirlendi. Sonuç olarak, saklama solüsyonlarının kompozitin mineye bağlanma dayanımı üzerinde farklı etkilere neden olabileceği görüldü.
Aim-, Teeth are stored in in vitro studies to prevent both dehydration of teeth collected and growth microorganisms in the storage solutions until they are used. The aim of this study was to determine the effect of three different solutions used to storage extracted teeth on the bond strength of a resin composite to enamel. Material and Methods: Sixty human non-carious permanent molars were used in this study. Immediately after extraction, the teeth were divided into three groups for storage solutions (0,1 % thymol, 10% formalin, distilled water). After 24 h at room temperature in thymol, formalin, distilled water storage, enamel surfaces were covered by a hybrid composite (36% phosphoric acid, Prime&BondNT, TPH) according to the manufacture's instructions. The restored teeth were replaced in its respective storage solution at 37°C for 24 h. The bonded specimens were serially sectioned with a water cooled diamond saw. The bond area of the sticks was approximately 1 mm2. The specimens were subjected to the micro-shear bond strengths test at a cross head speed of 1mm/min. Results and conclusion: It was found that the micro-shear bond strengths of the resin composite to enamel were 7.35±2.28 MPa, 8.48 ±2.38 MPa, 9.24±2.57 MPa in thymol, formalin and distilled water group respectively. Statistical evaluation were indicated that the teeth stored in thymol had statistically lower shear bond strength than those distilled water (p<0.05). There was no statistically difference between teeth stored in formalin and distilled water, formalin and thymol(p>0.05). As a conclusion, it was seen that storage solutions may have different effects on the bond strenght to enamel tissue of the resin composite.
