Curing efficiency of high-intensity light-emitting diode (LED) devices.
We evaluated the curing efficiency of 4 high-intensity light-emitting diode (LED) devices by assessing percentage of residual C=C (%RDB), surface microhardness (SM), depth of cure (DC), percentage of linear shrinkage-strain (%LS), and percentage of wall-to-wall contraction (%WWC). The light-curing units tested were a QTH light, the Elipar TriLight (3M/ESPE), and 4 LED devices - the Allegro (Den...
متن کاملa comparison of the shear bond strength of orthodontic brackets bonded with light-emitting diode and halogen light-curing units
statement of the problem: various methods such as light emitting diode (led) have been used to enhance the polymerization of resin-based orthodontic adhesives. there is a lack of information on the advantages and disadvantages of different light curing systems. purpose: the aim of this study was to compare the effect of led and halogen light curing systems on the shear bond strength of orthodon...
متن کاملcomparison of shear bond strength of orthodontic brackets bonded with halogen and plasma arc light curing
background: reduced time and appropriate bond strength of brackets is one of the most important aspects of orthodontic treatments. prolonged halogen light curing for bonding of brackets is undesirable, so the purpose of this study was to compare the shear bond strength of brackets bonded with halogen light and plasma arc system. materials and mehods: this was an experimental in vitro study. a t...
متن کاملShear bond strength of orthodontic brackets bonded using halogen light and light-emitting diode at different debond times.
The aim of this in vitro study was to compare the photoactivation effects of QTH (Quartz-Tungsten-Halogen) and LED (Light-Emitting Diode) on the SBS (Shear Bond Strength) of orthodontic brackets at different debond times. Seventy-two bovine lower incisors were randomly divided into two groups according to the photoactivation system used (QTH or LED). The enamel surfaces were conditioned with Tr...
متن کاملThe effect of a light-emitting diode on shear bond strength of ceramic brackets bonded to feldspathic porcelain with different curing times.
The aim of this study was to evaluate different curing times of a light-emitting diode (LED) unit on shear bond strength (SBS) of ceramic brackets bonded to feldspathic porcelain. Ceramic brackets were bonded with a light-cured adhesive to 96 feldspathic porcelain facets. Air-borne particle abrasion was performed using 25 mum aluminium trioxide (Al(2)O(3)) with an air abrasion device from a dis...
