TERMAL SİKLUSUN MİKROSIZINTIYA ETKİSİNİN SINIF V KAVİTELERDE KOMPOZİT RESTORASYONLARDA İN VİTRO İNCELENMESİ

Öz

Amaç: Bu çalışmanın amacı, termal siklusun sınıf V restorasyonlarda mikrosızıntısı üzerine etkisini in vitro koşullarda değerlendirmekti. Gereç ve Yöntem: Bu çalışmada 150 adet çürüksüz insan molar dişi kullanıldı. Dişlerin bukkal yüzeylerinde standardize sınıf V kaviteler hazırlandı. Her grupta 30 adet olacak şekilde dişler rastgele beş gruba ayrıldı. 1.grup: Clearfil S3 Bond, 2.grup: Xeno V, 3.grup: G Bond 4.grup: Optibond All In One 5.grup: iBond. Restorasyonlarda üretici firma tavsiyelerine uyuldu. Daha sonra dişler iki eşit (n=15) gruba ayrıldı. Birinci gruptaki dişlere (n=15) 55°C termal siklus işlemi 10.000 kez uygulandı. 2.gruba ise uygulanmadı. Tüm dişlerdeki dolguların 1 mm çevresi hariç dişler tamamen 2 kat tırnak cilası ile kaplandıktan sonra 24 saat 37 0C de % 0.5’lik metilen mavisinde bekletildi. Örneklerden alınan kesitlerin mikrosızıntı dereceleri stereomikroskop altında skorlandı. Elde edilen sonuçlar istatistiksel olarak Kruskal-Wallis ve Mann Whitney U testleri ile değerlendirildi. Bulgular: Gruplar arası mikrosızıntı skorlarında istatistiksel farklılık olduğu tespit edildi(p
