Are the low-shrinking composites suitable for orthodontic bracket bonding?
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...
متن کاملIn vitro orthodontic bracket bonding to porcelain.
This in vitro study investigated the influence of using different combinations of bracket, adhesive, and light-curing source on the tensile bond strength to porcelain and on failure patterns at debonding. Tensile tests were performed using: one ceramic bracket versus one metal bracket, two orthodontic composites; type bisphenol A-glycidyldimethacrylate and urethane dimethacrylate (UDMA), and fo...
متن کاملOrthodontic adhesives versus anterior restorative materials for bracket bonding.
Two hundred and forty Begg orthodontic brackets prewelded to a Dyna-Bond pad were bonded to bovine incisors using four orthodontic adhesives and four anterior restorative materials. Then samples of each material were tested after one day, three months, and six months immersion in lactic acid utilizing the Instron Universal Testing Instrument. The mean bond strength of each material at each time...
متن کاملEvaluation of a New Nano-filled Bonding Agent for Bonding Orthodontic Brackets as Compared to a Conventional Bonding Agent
Introduction: Recent advances in the field of material sciences have opened up a new horizon of options for bonding agents that can be used efficiently in orthodontics. The purpose of this study was evaluate and compare the shear bond strength (SBS) of the traditionally used Transbond XT and a newer nano-filled material Prime and Bond NT. Materials and methods: Sixty freshly extracted maxillary...
متن کاملAlginate Based Nano Composites for the Removal
Heavy metals discharged from various industries like electroplating, leather tanning, paint, textile and dying units are the primary cause of water pollution [1]. They pose serious threats to public health and environment due to their high toxicity, bio accumulative and non-biodegradable behavior [1,2]. Therefore, Water purification is emerging as a critical need for the researchers owing to th...
