Objective: The aim of this in-vitro study was to compare the microleakage of self-adhesive flowable composites to their counterparts applied with three different adhesive systems (3-step etch & rinse adhesive, 2-step self-etch adhesive, and 1-step self-etch adhesive) in Class V cavities.Materials and Methods: Seventy-five standardized Class V cavities were prepared on both buccal and lingual/palatinal surfaces of extracted non-carious human molar teeth. The occlusal margins were located on the enamel where the gingival margins were extended 1 mm below the cemento-enamel junction. Following preparation, all specimens were randomly divided into five groups: (1) self-adhesive flowable composite (Fusio Liquid Dentin, FLD), (2) selfadhesive flowable composite (Vertise Flow, VF), (3) 3-step etch & rinse adhesive/Flowable c omposite (Optibond FL/Clearfil Majesty Flowable, 3ER-AK), (4) 2-step self-etch adhesive/Flowable composite (Clearfil SE Bond/Clearfil Majesty Flowable, 2SE-AK), (5) 1-step self-etch adhesive/Flowable composite (Clearfil S3 Bond Plus/Clearfil Majesty Flowable, 1SE-AK). After thermocycling and immersion in a 0.5% basic fuchsin, the restorations were sectioned and dye penetration was evaluated under a stereomicroscope (n=30). The data were statistically analyzed with Kruskal-Wallis, Mann-Whitney U and Wilcoxon Signed Ranks tests (α=0.05).Results: At the enamel interface, no significant differences were observed between the microleakage scores of VF, FLD and 3ER-AK, while they showed significantly lower leakage scores than 2SE-AK and 1SE-AK (p < 0.05). At the dentin interface, 3ER-AK and 2SE-AK exhibited lower leakage scores than VF, FLD and 1SE-AK (p < 0.05). VF, FLD, 1SE-AK had higher leakage scores at the gingival margins (p < 0.05), while higher scores were detected at the enamel margins in 2SE-AK (p<0.05).Conclusions: Both self-adhesive flowable composites showed similar microleakage scores to the 3-step etch & rinse adhesive/flowable composite in enamel, whereas their performance in dentin was worse than 3-step etch & rinse adhesive/flowable composite and 2-step self-etch adhesive/flowable composite
Amaç: Bu in vitro çalışmanın amacı; sınıf V kavitelere uygulanan kendinden bağlanabilen akışkan kompozitler ile üç farklı adeziv sistemle (etch & rinse, iki aşamalı self-etch ve tek aşamalı self-etch) birlikte uygulanan akışkan kompozitlerin mikrosızıntı değerlerinin karşılaştırılmasıdır.
Gereç-Yöntem: Çürüksüz insan molar dişlerinin bukkal ve lingual/palatinal yüzeylerinde yetmiş beş adet standart sınıf V kavite hazırlandı. Kavitelerin oklüzal kenarları minede gingival kenarları dişeti kenarından mine-sement birleşiminin 1 mm altında olacak şekilde yer aldı. Preperasyonu tamamlanan örnekler, rastgele 5 alt gruba ayrıldı: (1) self-adeziv [Fusio Liquid Dentin (FLD)], (2) self-adeziv [Vertise Flow (VF)], (3) adeziv (etch & rinse) [Gel Etchant/Optibond FL/Clearfil Majesty Flowable] (3ER-AK), (4) adeziv (iki aşamalı self-etch) [Clearfil SE Bond/Clearfil Majesty Flowable] (2SE-AK), (5) adeziv (tek aşama self-etch) [Clearfil S3 Bond Plus/Clearfil Majesty Flowable] (1SE-AK). Termal siklüs ve %0.5’lik bazik fuksin boya uygulamasından sonra, örneklerden kesitler alındı ve stereomikroskop altında boya penetrasyon dereceleri skorlandı (n=30). Sonuçlar istatiksel olarak Kruskal-Wallis, Mann-Whitney U ve Wilcoxon Signed Ranks testleri uygulanarak değerlendirildi.
Bulgular: Kavitelerin mine yüzeyinde; VF, FLD, 3ER-AK grupları arasında istatistiksel olarak anlamlı bir fark göstermezken, 2SE-AK ve 1SE-AK grupları istatistiksel olarak anlamlı derecede daha yüksek mikrosızıntı değerleri gösterdi (p < 0.05). Kavitelerin dentin yüzeyinde ise 3ER-AK ve 2SE-AK grupları, VF, FLD ve 1SE-AK gruplarından istatistiksel olarak anlamlı derecede düşük mikrosızıntı değerleri gösterdi (p< 0.05). 2SE-AK ve 1SE-AK grupları mine yüzeyinde daha yüksek mikrosızıntı değerleri gösterirken, VF ve FLD grupları dentin yüzeyinde daha fazla mikrosızıntı değeri gösterdi (p<0.05).
Sonuç: Kendiden bağlanabilen akışkan kompozitlerin her ikisi de mine yüzeyinde etch & rinse adeziv/akışkan kompozitle benzer mikrosızıntı değerleri göstermiştir. Dentin yüzeyinde ise kendiden bağlanabilen akışkan kompozitler, etch & rinse adeziv/akışkan kompozit ve iki aşamalı self-etch adeziv/akışkan kompozit gruplarına göre daha fazla mikrosızıntı oluşturmuştur.
