This study evaluated the effect of flowable composite resin application on the microtensile bond strength (microTBS) of adhesive systems to dentin. Occlusal surfaces of human third molars were ground to obtain flat dentin surfaces. The crown of each tooth was sectioned occluso-gingivally into four quarters with a water-cooled diamond saw. One of the following adhesive systems was applied to den...

PURPOSE The aim of this work is to study and compare the retention rate, caries-preventing and antibacterial effects of resin-modified glass ionomer and flowable composite in comparison to conventional fissure sealant. METHODS Forty-five children aged 7-10 years with newly erupted lower first permanent molars were randomly divided into three equal treatment groups. Group I: sealed by a conven...

The purpose of this study was to evaluate the influence of power density on contraction stress of resin composite restorative materials during photo-polymerization. Six flowable resin composites, and a hybrid resin composite for comparison, were used. The composites were polymerized with the power density adjusted to either 100 or 600 mW/cm(2). Stress development was determined with a custom-ma...

Objectives: The aim of this investigation was to assess the influence of different surface treatments and repair material on the repair shear bond strength (SBS) of GC Fuji IX GP Packable Posterior Restorative, Filtek Bulk Fill, and Filtek Supreme Ultra Flowable. Methods: Thirty cylindrical specimens were prepared from each material and randomly allocated into 3 groups/10 each. Group 1: no surf...

The purpose of this investigation was to measure and compare both the surface roughness and gloss of flowable composites polished with standardized silicone carbide (SiC) papers. Four flowable and two conventional composites were used in this study. Polymerized specimens were subjected to a polishing procedure comprising 12 sequential steps from coarser to finer grits of SiC paper. At the initi...

abstract: introduction: ditching and marginal defects of amalgam restorations can cause microleakage, recurrent carries, pulp hypersensitivity and finally loss of the tooth. the complete replacement of large restoration is time consuming, difficult and may potentially damage the pulp. therefore in cases were there is no sings of recurrent caries, composite repair can be chosen as an alternative...

BACKGROUND/AIM The main drawback of flowable dental composite resin is low strength compared to conventional composite resin, due to a low amount of filler, neccessary for achieving low viscosity and ease of handling. The aim of this study was to improve mechanical properties of flowable dental composite resin by adding small amount of nanoparticles, which would not compromise handling properti...

AIM The aim of this study was to assess the effect of repeated (twice) applications of two fluoride varnishes (Duraflor and CavityShield) on the surface micromorphology of a high-viscosity glass ionomer (Fuji IX GP), a compomer (F2000), and a flowable composite (Filtek Flow) using a profilometer and scanning electron microscope (SEM). METHODS AND MATERIALS Fifteen specimens were prepared from...
