Geçici ve Daimi Simanların Dentine Olan Bağlanma Dayanımı Üzerine Manyetik Rezonans Görüntüleme İşleminin Etkisinin Araştırılması
Özet
Amaç: Bu çalışmanın amacı, geçici ve daimi simanlar ile simante edilmiş Co-Cr metal örneklerin dentine bağlanma dayanımına manyetik rezonans görüntülemenin (MRG) etkisini araştırmaktır.
Gereç ve Yöntem: Bu çalışmada 40 adet çekilmiş çürüksüz insan molar dişi, kullanılan siman sistemine göre ve MRG işleminin uygulanması durumuna göre rastgele gruplara ayrıldı (n=10). Co-Cr metal örnekler 7 mm çapında ve 3 mm kalınlığında olacak şekilde lazer sinterleme yöntemi ile üretildi. Dişlerin okluzal yüzeyindeki mine dokusu elmas bıçak ile ayrıldıktan sonra, örnekler seçilen siman sistemine uygun şekilde simante edildi ve planlanan gruplara MRG işlemi uygulandı. Her iki siman sisteminin kontrol gruplarına ise MRG uygulanmadı. Örnekler 24 saat 37oC suda bekletilip, universal test cihazına yerleştirildi. MRG işleminin bağlanma dayanımı üzerine etkisi makaslama bağlanma dayanım testiyle ölçüldü. Veriler megapascal cinsinden kaydedildi.
Bulgular: Daimi siman sistemi kullanılan grup değerlendirildiğinde, MRG uygulanmış grubun (2.27±0.39) makaslama bağlanma dayanımı, MRG uygulanmamış gruba (2.62±0.44) göre daha düşük bulundu ancak bu fark istatistiksel olarak anlamlı değildi (p>0.05). Benzer şekilde, geçici siman sistemi kullanılan grup değerlendirildiğinde, MRG uygulanmış grubun (0.50±0.22) makaslama bağlanma dayanımı, MRG uygulanmamış gruba (0.85±0.30) göre daha düşük bulundu ancak bu fark istatistiksel olarak anlamlı değildi (p>0.05).
Sonuç: Co-Cr metal alaşımıyla üretilmiş restorasyon kullanan bireylerde, 15 dakika süreyle 1.5-T MRG uygulanması, restorasyonun dentine olan bağlanma dayanımını azaltır ancak bu durum klinik olarak anlamlı olabilecek düzeyde değildir.

The Effect of Magnetic Resonance Imaging on the Bond Strength of Temporary and Permanent Cements to Dentin Surface
Abstract
Aim: The aim of this in vitro study is to evaluate the effect of magnetic resonance imaging (MRI) on the adhesion of Co-Cr metal specimens cemented with permanent and temporary cements to dentin surface.
Material and Methods: In this study, forty extracted human molar teeth without caries were randomly divided into subsets (n = 10) based on application of MRI and dental cement system. Co-Cr metal specimens were fabricated using laser sintering system in the final dimensions of 7 mm in diameter and 3 mm in thickness. After separating the enamel tissue on the occlusal surface of the teeth with a diamond blade, the samples were cemented with selected cement system and MRI was applied to the planned groups. MRI was not applied to the control groups of both cement systems. The samples were kept in 37oC water for 24 hours and placed to the universal test device. Shear bond strength test was performed to assess the effect of MRI on the adhesion of metal specimens to dentin surface. Data were expressed in megapascals.
Results: In the permanent cement group, the shear bond strength values of the MRI group (2.27±0.39) was lower than that of the without MRI group (2.62±0.44), but this difference is not reached significance level (p>0.05). Similarly, in the temporary cement group, the shear bond strength values of the MRI group (0.50±0.22) was lower than that of the without MRI group (0.85±0.30), but this difference is not reached significance level (p>0.05).
Conclusion: In patients using prosthesis made of Co-Cr alloy, MRI for 15 minutes decreases the bond strength of the restoration to dentin surface, but this is negligible.
Keywords. Permanent cement, temporary cement, magnetic resonance imaging, shear bond strength
