Dentin 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...
متن کاملLight curing of resin-based composites in the LED era.
This review thoroughly accumulated information regarding new technologies for state-of-the-art light curing of resin composite materials. Visible light cured resin-based composites allow the dentist to navigate the initiation of the polymerization step for each layer being applied. Curing technology was regularly subjected to changes during the last decades, but meanwhile the LED era is fully e...
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 کاملCuring effectiveness of resin composites at different exposure times using LED and halogen units.
OBJECTIVE To compare the polymerization effectiveness of two resin composites cured with a quartz tungsten halogen (QTH) lamp or a light emitting diodes (LED) unit. STUDY DESIGN Filtek Z250 (3M ESPE) and Spectrum TPH (Dentsply DeTrey) resin composites were placed in 9 mm deep and 4 mm wide metallic molds and cured using the QTH light Hilux 200 (Benlioglu) or the LED unit Smartlite IQ (Dentspl...
متن کاملstudying room temperature curing of phenolic resin and their composites
phenolic resins are synthetic low molecular weight thermoset resins which are polymerized and cured to higher molecular weights by condensation method. these resins have high weathering resistance, high oxidative thermal properties and good chemical resistance. phenolic resins can be cured thermally or by acid curing. the most common method of curing phenolic resin is by thermal curing that tak...
