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 ...
Heat Development in the Pulp Chamber During Curing Process of Resin-Based Composite Using Multi-Wave LED Light Curing Unit
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-08)
<i>Objective</i>: The study aimed to investigate factors contributing to heat development during light curing of a flowable bulk-fill resin-based composite (SDR<sup>TM</sup>, Lot # 602000876, Dentsply Sirona, Konstanz, Germany) (RBC).<p><p> <i>Materials and Methods</i>: Temperatures were measured with calibrated thermocouples. A multi-wave light-emitting diode (LED) light curing unit (LCU) was ...
Quantification of porosity in composite resins delivered by injectable syringes using X-ray microtomography
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-06)
<i>Objective</i>: To assess whether composite polymer resin delivered in compules include pores and the possible effect on the amount of porosity in dental restorations.<p> <p><i>Method and materials</i>: Original compules containing unpolymerised composite polymer resin (CPR) were scanned in a micro-CT. Four products were examined, which comprised universal composites (Herculite XRV Ultra, Ceram.X ...
In vitro Candida albicans biofilm formation on different titanium surface topographies
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-09)
<i>Objectives</i> - To investigate if differences in titanium implant surface topography influence <i>Candida albicans</i> biofilm formation.<p> <p><i>Materials and Methods</i> - Titanium discs were prepared and characterized using a profilometer: Group A (<i>R</i><sub>a</sub> 0.15 µm, smooth), Group B (<i>R</i> <sub>a</sub> 0.64 µm, minimally rough) and Group C (<i>R</i> <sub>a</sub> 1.3 µm, ...
