  • The Global ETD Search service is a free service for researchers to find electronic theses and dissertations. This service is provided by the Networked Digital Library of Theses and Dissertations.
    Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Surface hardness of different shades and types of resin composite cured with a high power led light curing unit.

Lodhi, Tariq Abbas January 2006 (has links)
<p>Light-emitting diode (LED) curing lights were introduced to the dental market promising a higher curing efficiency than halogen-based lights. The earlier generation curing lights, however, proved not to be as effective as halogen lights. As a result 3M ESPE introduced a new high-powered LED curing light, the Elipar FreeLight 2, that delivers a greater irradiance. and threfore greater energy density than its precursor. Due to these changes, the light's manufacturer claims that the FreeLight 2 can cure resin composites at half of their recommended curing time. The aim of this study was to compare the effectiveness of cure when a FreeLight 2 was used to sure composite samples at 100% and at 50% of the recommended curing time.</p>

The effect of storage time on dimensional accuracy of elastomeric impression materials.

Osio, Mary A. January 2008 (has links)
<p>&quot / Several factors play a role in stability of impressions made from elastomeric impression materials. These include / polymerization shrinkage, loss of by-products during condensation, thermal contraction from oral temperature to room temperature, imbibition when exposed to water, disinfectant or high humidity and incomplete recovery from deformation due to viscoelastic behavior. An ideal impression material should be dimensionally stable over time to allow for pour at the convenience of the operator. Several studies evaluated the dimensional accuracy of elastomeric impression materials based on various factors including effects of repeat pour, temperature, humidity, disinfectants, impression techniques, and filler loading amongst others. Most of the previous studies did not use the standardized method described by the ADA specification for elastomeric impression materials...&quot / </p>
