Light-curing units used in dentistry: Effect of their characteristics on temperature development in teeth Open
This study aimed to investigate pulp chamber and surface temperature development using different LED light curing units (LCUs). Eight brands of LED-LCUs were tested in a laboratory bench model. The pulp chamber and surface temperature were…

Heat Development in the Pulp Chamber During Curing Process of Resin-Based Composite Using Multi-Wave LED Light Curing Unit Open
The irradiance of the LCU seemed to be a more important factor than exothermic reaction of RBCs for pulp chamber heat development. Flowable bulk-fill RBCs can act as a pulpal insulator against LCU irradiation, despite their exothermic curi…

<i>In vitro Candida albicans</i> biofilm formation on different titanium surface topographies Open
To investigate if differences in titanium implant surface topography influence Candida albicans biofilm formation. Titanium discs were prepared and characterized using a profilometer: Group A (Ra 0.15 µm, smooth), Group B (Ra 0.64 µm, mini…

Quantification of porosity in composite resins delivered by injectable syringes using X-ray microtomography Open
All the composite polymer resin compules contained unpolymerised material that included pores. The universal composite compules included pores predominantly in the sub-100 µm sizes. In contrast, the flowable bulk-fill compules included a f…

Light-curing units used in dentistry: factors associated with heat development—potential risk for patients Open
Risk of superficial tissue damage at irradiances >1200 mW/cm2 is evident. There is a risk of pulp damage when only thin dentin is left at higher irradiances (>1200 mW/cm2). Clinicians should be aware of LED-LCU settings and possible high t…
