Abstract

Objective: The aim of this in vitro study was to evaluate and compare the effect of using different base materials on microleakage of class V restorations.Materials and Method: In this study 60 extracted non-cavitated human molar teeth were used. Class V cavities were prepared on the buccal surfaces in 4 mm mesio-distal, 3 mm gingivo-occlusal width and 3 mm depth. The teeth were randomly divided into five groups: Group 1: resin-modified calcium silicate material (TheraCal LC), Group 2: self-adhesive flowable composite resin (Fusio Liquid Dentin), Group 3: flowable composite resin liner (Tetric N Flow), Group 4: resin-modified glass ionomer liner (Ketac N100), Group 5: control group. Materials in the experimental groups were placed in 1 mm thickness as liner. Then, a nanohybrid composite resin (Grandio) was placed and restorations were completed. In the control group, no base material was applied. After finishing and polishing procedures, thermocycling was performed 5000 times between 5-55 °C. Microleakage of restorations was evaluated by using dye penetration method (basic fuchsin). Results were analyzed by Kruskal Wallis with Bonferroni correction and Mann-Whitney U tests.Results: Regarding occlusal microleakage, no statistically significant difference was found between the groups (p=0.267); however significant difference was found between the gingival microleakage scores (p=0.004). Compared to Fusio Liquid Dentin and control groups, significantly less dye penetration was found in Theracal LC, Tetric N-Flow and Ketac N-100 groups (p<0.01). No significant difference was found between the occlusal and gingival sides of the restorations in any of the test group (p>0.01).Conclusion: Within the limitation of this study, the conclusion was that the use of a liner (except Fusio Liquid Dentin) under composite resin in a class V cavity reduced the microleakage of the restoration.

Özet

Amaç: Bu çalışmanın amacı, sınıf V restorasyonların mikrosızıntısı üzerine farklı kaide materyallerinin kullanımının etkisini in vitro olarak incelemektir.Gereç ve Yöntem: Çalışmada 60 adet çekilmiş, çürüksüz büyük azı dişi kullanıldı. Dişlerin bukkal yüzeyinde mezio-distal genişliği 4 mm, okluzo-gingival genişliği 3 mm ve derinliği 3 mm olan sınıf V kaviteler hazırlandı. Daha sonra, dişler rastgele beş gruba ayrıldı: Grup 1: rezin modifiye kalsiyum silikat materyal (TheraCal LC), Grup 2: kendinden pürüzlendirmeli akışkan kompozit rezin (Fusio Liquid Dentin), Grup 3: akışkan kompozit rezin (Tetric N-Flow), Grup 4: nanodolduruculu rezin modifiye cam iyonomer siman (Ketac N100), Grup 5: kontrol grubu. Deney gruplarında, kaide materyalleri kavite tabanlarına 1 mm kalınlığında yerleştirildi. Üzerlerine A2 renginde nanohibrit dolduruculu kompozit rezin (Grandio) yerleştirilerek restorasyonlar tamamlandı. Kontrol grubunda ise herhangi bir kaide materyali kullanılmadı. Bitim ve polisaj işlemlerinden sonra, dişlere 5-55 °C’de 5000 defa ısısal döngü uygulandı. Dişlerin mikrosızıntı değerlendirmeleri boya sızıntı yöntemi (%0.5 bazik fuksin) kullanılarak gerçekleştirildi. Elde edilen skorlar, Bonferroni düzeltmeli Kruskal Wallis ve Mann-Whitney U testleri kullanılarak istatistiksel olarak incelendi.Bulgular: Çalışmadaki tüm deney gruplarında, restorasyonların okluzal bölgelerindeki mikrosızıntı skorları arasında istatistiksel olarak anlamlı fark bulunmazken (p=0.267), gingival bölgedeki mikrosızıntı skorları arasında istatistiksel olarak anlamlı farklılık olduğu görüldü (p=0.004). Buna göre, Fusio Liquid Dentin ve kontrol gruplarına göre sırasıyla, Theracal LC, Tetric N-Flow ve Ketac N-100 gruplarının sızdırmazlıklarının anlamlı olarak daha iyi olduğu görüldü (p<0.01). Tüm deney gruplarında okluzal ve gingival bölgelerde gözlenen mikrosızıntı skorları arasında istatistiksel olarak anlamlı farklılığın olmadığı tespit edildi (p>0.01).Sonuç: Bu çalışmanın sınırları dahilinde sınıf V restorasyonlarda kaide materyali kullanımının (Fusio Liquid Dentin hariç) gingival bölgedeki mikrosızıntıyı azalttığı görüldü.
