Fracture resistance of computer-aided design/computer-aided manufacturing-generated composite resin-based molar crowns
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-16)
The aim of this study was to investigate whether different fabrication processes, such as the computer-aided design/computer-aided manufacturing (CAD/CAM) system or the manual build-up technique, affect the fracture resistance of composite resin-based crowns. Lava Ultimate (LU), Estenia C&B (EC&B), and lithium disilicate glass-ceramic IPS e.max press (EMP) were used. Four types of molar crowns were ...
Fracture resistance of monolithic zirconia molar crowns with reduced thickness
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-30)
Objectives. The purpose of the present study was to analyze the relationship between fracture load of monolithic zirconia crowns and axial/occlusal thickness, and to evaluate the fracture resistance of monolithic zirconia crowns with reduced thickness in comparison with that of monolithic lithium disilicate crowns with regular thickness. Materials and methods. Monolithic zirconia crowns (Lava ...
Photo-irradiated caffeic acid exhibits antimicrobial activity against Streptococcus mutans biofilms via hydroxyl radical formation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-25)
An antimicrobial technique based on photo-oxidation of caffeic acid (CA) has recently been developed, but its effect on biofilm-forming bacteria is unknown. The present study aimed to evaluate the effect of photo-irradiated CA against Streptococcus mutans (cariogenic bacteria) biofilm as it relates to hydroxyl radical formation. S. mutans biofilms grown on hydroxyapatite disks were immersed in CA ...
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 ...
