متن کاملIn vitro evaluation of microleakage under ceramic and metal brackets bonded with LED and plasma arc curing.
AIM The aim of the present study was to evaluate these two high intensity light curing units regarding microleakage beneath metal and ceramic brackets. MATERIALS AND METHODS A total of 60 freshly extracted human premolar teeth were randomly divided into four groups of 15 samples; group I: Metal bracket + LED cured, group II: Ceramic bracket + LED cured, group III: Metal bracket + plasma arc c...
متن کاملColor Stability of a Microhybrid Resin Composite Polymerized with LED and QTH Light Curing Units
Introduction: Discoloration of resin composites is a common reason for replacement of these restorations. The aim of this study was to eva-luate the influence of different light curing de-vices on color stability of a microhybrid resin composite. Materials and Methods: 80 disc-shaped speci-mens (8 mm in diameter, 2-mm height) were fabricated from filtek Z250 resin composite. Specimens wer...
متن کاملLED vs halogen light-curing of adhesive-precoated brackets.
OBJECTIVE To test the hypothesis that bonding with a blue light-emitting diode (LED) curing unit produces no more failures in adhesive-precoated (APC) orthodontic brackets than bonding carried out by a conventional halogen lamp. MATERIALS AND METHODS Sixty-five patients were selected for this randomized clinical trial, in which a total of 1152 stainless steel APC brackets were employed. In or...
