statement of the problem: enamel and dentin marginal sealing ability of the new adhesive materials could play an important role in successful restoration on fluorosed teeth. purpose: the aim of this in vitro study was to evaluate the marginal microleakage of low-shrinkage silorane-based composite, nano-ionomer, and methacrylate-based composite through self-etching approach or with enamel acid e...

introduction: although composite resins have improved greatly since their introduction, microleakage is one of the most frequently encountered problems. this study compared the effects of different monomer systems and layering techniques on the bacterial leakage of cl i composite resin restorations. methods: eighty-two sound human third molars were used. the teeth were randomly divided into six...

The surface roughness of dental restorative materials has a crucial effect on the health of dental and periodontal tissues as well as for the longevity of restorations. In this study we tested a glass ionomer restorative cement, two nanohybrid resin composites, a flowable resin composite and a silorane-based composite. Twenty cylindrical specimens of each material were prepared, cured, polished...
