PURPOSE To evaluate the shear bond strength (SBS), adhesive remnant index (ARI), and microleakage of low-shrinking and conventional composites used as an orthodontic bracket bonding adhesive. MATERIALS AND METHODS A hundred twenty non-caries human premolars, extracted for orthodontic purposes, were used in this study. Sixty of them were separated into two groups. Brackets were bonded to the t...

The present investigation observed the sealing ability of low shrinkage composite resins in large and deep cavities, placed and photocured in one increment. Large, deep cavities (5.0 mm diameter and 2.5 mm deep) surrounded by enamel were prepared in bovine teeth, which were then divided into five groups. Groups 1, 2, 3 and 4: acid conditioning + Adper Single Bond (3M/ESPE, St Paul, MN, USA) and...

After the establishment of composite as a restorative material, there was an attempt to categorise the different composite types according to filler size (Lutz & Philips 1983). This classification does not do justice to today’s composites, since most of the composite materials belong to the nanocomposites, nano-filled composites, nano-filled hybrid composites or micro-hybrid composites. Althoug...
