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 کاملEffect of reduced exposure times on the microhardness of 10 resin composites cured by high-power LED and QTH curing lights.
PURPOSE To compare the effect of reduced exposure times on the microhardness of resin composites cured with a "second-generation" light-emitting diode (LED) curing light and a quartz-tungsten-halogen (QTH) curing light. METHODS Ten composites were cured with a LED curing light for 50% of the manufacturers" recommended exposure time or a QTH light at the high power setting for 50% of the recom...
متن کاملModern high powered led curing lights and their effect on pulp chamber temperature of bulk and incrementally cured composite resin.
Pulpal temperature changes induced by modern high powered light emitting diodes (LEDs) are of concern when used to cure composite resins. This study showed an increase in pulp chamber temperature with an increase in power density for all light cure units (LCU) when used to bulk cure composite resin. Amongst the three LEDs tested, the Elipar Freelight-2 recorded the highest temperature changes. ...
متن کاملThe effect of distance from light source on light intensity from curing lights.
PURPOSE To investigate how light intensity changes as the distance increases from the tip of the light guide. MATERIALS AND METHODS Ten different curing light/light guide combinations were used. Light intensity was measured at 0, 3, 6, and 10 mm from the tip of the light guide with a radiometer. Measurements were repeated in five separate trials and the mean light intensity +/- standard devia...
متن کاملDentin bond strength of composites with self-etching adhesives using LED curing lights.
AIM The purpose of this study was to investigate the effect of light-emitting diode (LED) light curing units (LCUs) compared with halogen LCUs on the shear bond strength (SBS) of one nanofill composite (Filtek Supreme) and one microhibrid composite (Artemis) with self-etch adhesives. METHODS AND MATERIALS The buccal surfaces of 60 non-carious extracted human molars were flattened to expose de...
