BACKGROUND This study aimed to evaluate the microleakage, when flowable composite is used as a restorative material and a liner. MATERIALS AND METHODS Forty, non-carious, extracted human premolar teeth were used and they were divided into five groups according to the type of composite material used. Group I: Hybrid composite was inserted and cured for 40 s. Group II: Flowable resin composite ...

This study was designed to test the hypothesis that the flowable/dentin interface has the weakest bond and highest frequency of failure when a resin-based composite is repaired using a flowable composite. Comparing three specific groups--dentin, flowable composite, and hybrid composite-under the Kruskal-Wallis test showed that the mean bond strength values at the flowable/dentin interface and w...

Background and purpose: Antibacterial properties of restorative materials are of great advantage as they control the progression of tooth decay. The use of self-adhesive composite materials has some benefits such as easier application and reduced treatment time. Because the antibacterial properties of restorative materials can play an important role in preventing secondary decay, especially in ...

objective: long-term retention of pit and fissure sealants is crucial for their success. this clinical study evaluated the retention rate of a flowable composite resin (filtek supreme xt flowable restorative) compared to a conventional resin-based sealant (concise light cure white sealant) over 12 months. materials and methods: forty subjects aged 6 to 9 years were included in the study. using ...

OBJECTIVE Monomer development for a reduced shrinkage of composite materials still challenges the modern research. The purpose of this study was to analyse the shrinkage behavior of an innovative composite material for dental restorations based on a resin system that is claimed to control polymerization kinetics having incorporated a photoactive group within the resin. METHODS Shrinkage stres...

The purpose of this in vitro study was to evaluate marginal integrity and wall adaptation in 1- and 2-mm-deep cavities restored with a high filler-loaded flowable composite in comparison to a flowable composite with lower filler content and a conventional hybrid composite. 1-mm-deep dentin and 2-mm-deep enamel-dentin Class I cavities were prepared and restored with a self-etch adhesive and with...

This in vivo study evaluated the clinical performance and appearance of a flowable resin composite and a hybrid resin composite over two years. Twenty-eight (28) pairs of restorations of a flowable resin composite and a conventional hybrid resin composite were placed in non-carious, asymptomatic facial Class V lesions. The restorations were evaluated at baseline, six, twelve, eighteen and twent...

OBJECTIVES The aim of this study was to investigate the effect of layering methods, flowable composite liner and use of low shrinkage silorane-based composite on the polymerization shrinkage stress of light cured composites. METHODS Aluminum blocks were used to prepare MOD cavities and divided into four groups. A universal hybrid methacrylate-based composite (Z250), a flowable composite (Z350...

OBJECTIVES The aims of this investigation were to clarify the effects of 24h water-storage and finishing time on mechanical properties and marginal adaptation to a Class V cavity of eight modern flowable resin-composites. METHODS Eight flowable composites, plus two controls (one microfilled and one hybrid composite), were investigated with specimen sub-groups (n = 10) for each property measur...
