OBJECTIVE The purpose of this study was to evaluate the dynamic (storage) shear modulus and the static shear modulus of elasticity of packable and flowable composite resins and to investigate their development after initial photo-curing. METHODS Three pairs of a packable versus a flowable composite and a microfill composite resin were tested (Alert/Flow It, Filtek P60/Filtek Flow, Admira/Admi...

The newly introduced self-adhering flowable resin-composites Background: decrease the required time for application by incorporation of an acidic adhesive monomer, thus reducing the number of the steps, but its bonding is still uncertain. The aim of this study was to evaluate the interfacial microscopic examination and chemical analysis at the resin-dentin interface of a self-adhering flowable ...

OBJECTIVE To compare wear performance and resistance to crack propagation (K1C) of commercial restorative materials and their flowable variations. A potential correlation between three-body wear and fracture toughness, modulus of elasticity, fracture work, Vickers hardness, and filler content was investigated. METHOD AND MATERIALS Seven restoratives (five composites, one ormocer, and one comp...

Purpose: This study aimed to investigate if the hardness ratio of bulk-fill-type resin composite is higher than that hybrid-type composite, determine when radiant exposure was same, and polymerization composites at top bottom surfaces affected by differences in irradiance light sources. Methods: The light-curing unit used LED G-Light Prima-II Plus (blue + violet LED) unit. light-cured were Clea...

Introduction: One of the main disadvantages of composites is marginal microleakage using flowable composites as a liner beneath composite restorations has been recommended to reduce microleakage. The aim of this study was to assess the microleakage of class II restorations with different flowable composites liners. Materials & Methods :45 extracted premolars teeth with class II cavity prepar...

Improving the adaptation of resin composites during placement is necessary to increase durability and reduce microleakage. Flowable resin liners have been introduced to improve adaptation in composite restorations. In addition, a device that lowers the viscosity of regular dental composites has been introduced (Calset, AdDent Inc, Danbury, CT, USA). This device lowers the viscosity of composite...
