Abstract
Aims: Effect of composition of hybrid composites on their microleakage behavior was evaluated. Study Design: An invitro microleakage study. Place and Duration of Study: Department of Conservative Dentistry, Faculty of Dentistry, The University of Jordan, Amman, Jordan, between May 2012 and July 2013. Methodology: 160 Class V cavities were divided into four equal parts each restored with either “Spectrum”,“Admira”, “FilteckP90” or “Smart dentine replacement SDR”. Teeth were thermocycled, immersed in 1% methylene blue for four hours and sectioned buccolingually. AutoCAD software was used in delineating cavity outlines and depth of dye penetration. Data was treated using ANOVA, Turkey and t-tests at 95% confidence. Results: Spectrum displayed more intact interface at enamel margins than Filteck, P90 and Admira, similarly SDR interface to enamel was better than that of Admira® (p<0.05). Original Research Article AArticle Article British Journal of Medicine & Medical Research, 4(9) 1908-1922, 2014 1909 The materials’ interface at the gingival wall was of comparable nature. Conclusion: Variations of materials’ type or location of Class V cavity, buccal or lingual, does not affect the tooth/restoration bond interface. AutoCAD software proved to be a powerful measurement tool and is recommended for microleakage studies.
