This study evaluated the impact of extended etching and bonding strategies on the microshear bond strength of three sealant materials. Two pit-and-fissure sealants [FluroShield, Dentsply (light-cured) and AlphaSeal, DFL (self-cured)] and one light-cured flowable composite resin (Permaflo, Ultradent) were evaluated according to different enamel etching times (15 s or 30 s) and bonding procedures...

Introduction: Composite resins have excellent mechanical properties, including fast polymerization,aesthetic quality, easy handling, and the ability to adhere enamel surfaces. However, there are alsosome disadvantages from this material, one of them is residual monomers. Bulk-fill composite areavailable in sculptable (solid) flowable (liquid) form. Most resin matrix aromatic oraliphatic acrylat...

The purpose of this study was to examine three- and two-body wear values of flowable resin composites for posterior restorations, using a mechanical loading device. The cavities prepared on flattened extracted molars were restored with flowable resin composites (Clearfil Majesty LV: MLV, Estelite Flow Quick: EFQ, Beautifil Flow Plus F00: BFP, and MI Fill: MIF) using accompanying adhesive system...

The aim of this research was to study the impact using a short fiber-reinforced composite (SFRC) core on fatigue performance and fracture behavior direct large posterior restorations. Moreover, influence consistency (flowable or packable) occlusal coverage assessed. A total 100 intact molars were collected randomly distributed into five groups (n = 20). Deep mesio-occlusal-distal (MOD) cavities...

OBJECTIVE To assess microleakage of enamel-composite and wire-composite interfaces when retainer wires were bonded with two orthodontic and a flowable composites. MATERIALS AND METHODS Forty-five freshly extracted human mandibular canine teeth were used in this study. Teeth were separated into three groups of 15 teeth each. Round stainless-steel wire of 0.36-in. diameter in three groups was b...
