objectives: the aim of this study was to evaluate the effect of six herbal teas on the color stability of two types of nanohybrid and one microhybrid resin composite.  materials and methods: 70 disc-shaped specimens, 210 in total (7*2mm), were fabricated from each of the following materials in metal mould : tetric n ceram, grandio, gradia direct anterior. specimens were stored in distilled wate...

AIM – The aim of this study was to evaluate marginal sealing ability of newly introduced Dyad Flow with total etch & self-etch adhesive system at the coronal and apical margins of class V resin composite restorations. MethodsA standard class V cavity (3 mm mesiodistal width, 3 mm occlusogingival height, and 1.5 mm axial depth) was prepared on the buccal surface of freshly extracted sound human ...

BACKGROUND Microleakage is still one of the defects of resin composites that can lead to treatment failure; and re-bonding technique is one of the effective ways to reduce it. This study evaluated the effect of re-bonding with a surface sealant or a dentin adhesive on microleakage in class V microhybrid, nanohybrid, and packable composite restorations. MATERIALS AND METHODS In this in vitro s...
