Amaç: Bu in vitro çalışmanın amacı, farklı çok modlu adezivlerin üç asitleme modunda Sınıf V kompozit restorasyonların oklüzal ve gingival mikrosızıntısı üzerindeki etkilerini değerlendirmektir. Materyal ve Yöntem: Yüz yirmi insan moları rastgele dört gruba (G2-Bond Universal [GBU], Clearfil Tri-S Bond Universal [CTU], OptiBond Universal [OBU] ve Tokuyama Universal Bond [TUB]) ve ardından üç asitleme alt grubuna (total asitleme, kendinden asitli ve selektif asitleme) (n = 10) ayrıldı. Standart Sınf V kaviteler hazırlandı ve mikrohibrit bir kompozit rezin ile restore edildi. Tüm dişler, 5–55°C'de 30 saniye boyunca 10,000 kez termal siklusa maruz bırakıldı ve ardından 24 saat boyunca % 0,5 bazik fuksin çözeltisinde bekletildi. Dişler bukkolingual olarak kesildikten sonra, boya penetrasyonu ışık mikroskobu altında değerlendirildi. Ayrıca taramalı elektron mikroskobu analizi yapıldı. İstatistiksel değerlendirme için Kruskal-Wallis ve Mann-Whitney U testleri kullanıldı (p = 0,05). Sonuçlar: GBU, CTU, OBU ve TUB, sırasıyla kendinden asitli, selektif asitleme, total asitleme ve kendinden asitli modlarında en az mikrosızıntı skorunu göstermiştir. Kendinden asitli modunda, oklüzal kenarda GBU anlamlı derecede en az, CTU en çok mikrosızıntı gösterirken (p < 0,05), gingival kenarda adezivler arasında fark yoktu. Total asitleme modunda, GBU gingival kenarda en çok mikrosızıntı gösterirken (p < 0,05), oklüzal kenarda adezivler arasında anlamlı bir fark çıkmadı. Sonuç: Sınıf V kompozit restorasyonların oklüzal veya gingival mikrosızıntıları, adezivler ve asitleme modlarına bağlı olarak değişiklik göstermektedir.

The Effect of Different Multimode Adhesives On Microleakage of Class V Composite Restorations in Three Etching Modes

Öz

Objective: The aim of this in vitro study was to evaluate the effects of different multimode adhesives in three etching modes on occlusal and gingival microleakage of Class V composite restorations. Materials & Methods: One hundred and twenty human molars were randomly assigned to four groups (G2-Bond Universal [GBU], Clearfil Tri-S Bond Universal [CTU], OptiBond Universal [OBU], and Tokuyama Universal Bond [TUB]), and then three etching subgroups (total etch, self etch, and selective etch) (n = 10). Standard Class V cavities were prepared and restored with a microhybrid resin composite. All teeth were exposed to a 30-second thermal cycle for 10000 times at 5–55°C and then kept in 0.5% basic fuchsine solution for 24 hours. After the teeth were buccolingually cut, dye penetration was evaluated under a light microscope. Scanning electron microscopy analysis were also performed. Kruskal–Wallis and Mann–Whitney U tests were used for statistical evaluation (p  0.05). Results: GBU, CTU, OBU, and TUB showed the least microleakage score with self etch, selective etch, total etch and self etch modes, respectively. In self etch mode, GBU had the least and CTU had the most microleakage on occlusal margin (p < 0.05), while there was no difference among adhesives on gingival margin. In total etch mode, GBU had the most microleakage on gingival margin (p < 0.05), while there was no difference on occlusal margin among adhesives. Conclusion: Occlusal or gingival microleakages of Class V composite restorations vary depending on the adhesives and etching modes.
