OBJECTIVES The purpose of this in vitro study was to evaluate shear bond strengths and microleakage of seven current-generation dentin adhesive systems. METHODS Standard box-type Class V cavity preparations were made at the cemento-enamel junction on the buccal surfaces of eighty extracted human molars. These preparations were restored using a microfill(More)
OBJECTIVES The cure of all resin-modified glass ionomer materials depends to some degree on light activation. However, the materials have chemical-cure mechanisms that could increase depth of cure. Thus, this study was conducted to evaluate the depth of cure of five resin-modified glass ionomer restorative materials. METHODS Five specimens of Fuji II LC(More)
A new tool was developed and validated on an X-ray dummy to allow personalized design and adjustment of spinal braces. The 3D visualization of the external trunk surface registered with the underlying 3D bone structures permits the clinicians to select pressure areas on the trunk surface for proper positioning of correcting pads inside the brace according(More)
BACKGROUND During the past 25 years, advances in adhesive technology and composite-based resins have provided dentists and patients with new treatment options. This technology provides patients with more tooth-conserving and highly esthetic restorations. CLINICAL IMPLICATIONS This article reviews advances in composite-based resin materials. It discusses(More)
PURPOSE The purpose of this in vitro study was to investigate and compare the microleakage-occurring after the placement of a light-curing sealant-to unground permanent enamel which had been previously conditioned using 3 different application protocols. METHODS Sixty-three molars were randomly distributed in 3 different groups according to the(More)
PURPOSE The purpose of this study was to compare sealant-enamel bond strengths of 3 application protocols. METHODS Sixty extracted third molars were randomly distributed into 3 groups according to the sealant's application protocol. The enamel was conditioned with: phosphoric acid in group 1; phosphoric acid and a single-bottle dentin bonding agent in(More)
PURPOSE To evaluate the bonding between resin composites and resin-modified glass ionomer restorative materials. MATERIALS AND METHODS Bar-shaped specimens of Fuji II LC, Photac-Fil, and Vitremer were fabricated in a mold. After application of unfilled resin, resin composite (either Silux Plus or Restorative Z100) was condensed into the mold against the(More)
PURPOSE To determine the effect of All-Bond 2 adhesive on the shear bond strengths to dentin of Fuji II LC, Photac-Fil, and Vitremer. MATERIALS AND METHODS The occlusal surfaces of 60 extracted human third molars were ground flat to expose dentin and were polished to 600 grit. The teeth were randomly assigned to six groups (n = 10). In three groups,(More)
