The Effect of Silane Content on Microleakage of the Adhesive Systems

OpenAlex İngilizce

Aim: The aim of this study is to compare to microleakage levels of two silane based adhesive systems and one silane free adhesive system.Material and Method: Thirty standardized freshly extracted sound premolar teeth were used in study. Teeth were randomly and divided into three groups of 10 teeth each, according to the adhesive systems n=20 . Class V cavities were prepared mesio-distal 4 mm, and occluso-gingival 3 mm, and 2 mm depth . After the adhesive systems were applied Clearfil Universal Bond- silane based, Single Bond Universal-silane based and Adper Single Bond 2-silane free composite resins Filtek Z 250 were built up to the cavities. The specimens were aged with 5,000 thermocycles and immersed in 0.5% basic fuchsine solution during 24 hours. Then the samples were sectioned longitudinally in bucco-lingual and mesiodistal directions. The slices were observed under a stereomicroscope X40 magnification . The scores were statistically analyzed using the Kruskal-Wallis and the Mann Whitney U tests.Results: Significant differences were found in microleakage values among the adhesive systems p
