“…This is because the cervical margin has less thickness of enamel layer than occlusal margin. Also, there are other reasons such as the difference of the organic nature of dentine substrate between occlusal and cervical margins, different histological structure between occlusal and cervical margins and less hydroxyapatite crystals at the cervical margins (18).…”

INTRODUCTION:Advances in flowable composites including self-adhesive and bulk fill flowable composite resin have been introduced for time saving and better adaptation. OBJECTIVES: was to compare the microleakage and shear bond strength of Self-adhesive& Bulk fill flowable composite resins. MATERIAL AND METHODS: A total of forty non carious extracted human molars were selected for this study. For microleakage test, twenty Class V cavities were prepared on labial surface. Teeth were divided into 2 groups (n=10), Group I: was treated with self-adhesive flowable composite, Group II: was treated with one step self-etch adhesive system with bulk fill flowable composite. Microleakage scores were evaluated on the occlusal and cervical walls and data was analyzed statistically. For Shear bond strength test, twenty molars were embedded in acrylic resin inside plastic molds; the occlusal portion of each tooth was removed. To standardize the bonding area, cylindrical shaped plastic matrices with 4mm internal diameter and 3mm height were used. Specimens were divided into 2 groups (n=10), Group I: was treated with selfadhesive flowable composite, Group II: was treated with one step self-etch adhesive system with bulk fill flowable composite. Shear bond strength was measured using universal testing machine. RESULTS:The cervical margins showed a non-significant higher mean of microleakage scores than the occlusal margins in the two studied restorative materials. Filtek flowable bulk fill composite showed significantly higher mean of microleakage scores than Vertise flow at both the cervical and occlusal margins. Filtek flowable bulk fill composite showed a significantly higher mean of shear bond strength than Vertise flow. CONCLUSIONS: All of the restorative materials used were unable to prevent microleakage. Filtek flowable bulk fill composite showed more microleakage but higher shear bond strength than Vertise flow.

“…9 Microleakage in restorative materials is a big problem in clinical dentistry. 10 Composite may exhibit reduced properties along time, which increases it susceptibility to wear and marginal microleakage when in contact with liquids.…”

Aim:The purpose of this study was to determine the effect of different solutions cola soft drink (CSD) and coffee on roughness and microleakage of composite resin restorations. Materials and methods:Sixty bovine incisors were prepared and restored using Filtek Z350 XT (3M/ESPE) nanoparticulate resin. The samples were divided into three groups (n = 20): A (control)-Immersion in artificial saliva (14 days); B: Immersion in coffee (14 days), for 15 minutes (3x/day) and C: Immersion in CSD for 14 days (3x/day). Then the samples were analyzed for microleakage (dye penetration) and surface roughness (atomic force microscope). The one-way analysis of variance (ANOVA) was applied to assess the surface roughness and microleakage. The Tukey's test was set at 0.05. Results:Group A (roughness-GA R ) presented significantly the lowest average surface roughness. Group C (microleakage-GC M ) showed significantly the highest average microleakage. Conclusion:It was concluded that CSD and coffee change the surface roughness and increase the microleakage of restorations.
