Light-curing units used in dentistry: factors associated with heat development – potential risk for patients
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-01)
Objectives:<br>To investigate how heat development in the pulp chamber and coronal surface of natural teeth with and without cusps subjected to irradiance using light-emitting diode (LED)–light-curing units (LCUs) is associated with (i) irradiance, (ii) time, (iii) distance, and (iv) radiant exposure.<br>
Materials and methods:<br>Three different LED-LCUs were used. Their irradiance was measured ...
Effect of cements on fracture resistance of monolithic zirconia crowns
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-26)
Objectives - The present study investigated the effect of cements on fracture resistance of monolithic zirconia crowns in relation to their compressive strength.<p>
<p>Materials and methods - Four different cements were tested: zinc phosphate cement (ZPC), glass-ionomer cement (GIC), self-adhesive resin-based cement (SRC) and resin-based cement (RC). RC was used in both dual cure mode (RC-D) and ...
