To determine the degree of conversion (DC) and Knoop microhardness (KHN) of resin-based composites (RBCs) containing trimethylbenzoyl-diphenylphosphine oxide (TPO) cured by polywave or monowave LED light-curing units (LCUs). Three groups (each n = 5) of Tetric EvoCeram (Ivoclar Vivadent), Vit-l-escence
F H F Loureiro et al.
Minerva stomatologica, 60(10), 501-508 (2011-11-16)
This study evaluated the temperature change into the pulp chamber during the light curing of composite resin by direct (bovine tooth) and indirect (matrix) methods. Direct method: fifty standardized cavities (2x2x2 mm) were prepared in bovine incisors, which were randomly
Vesna Miletic et al.
Journal of dentistry, 40(2), 106-113 (2011-11-19)
To determine the degree of conversion (DC) over 48 h post-curing of resin mixtures containing trimethylbenzoyl-diphenylphosphine oxide (TPO) initiator cured by a polywave or a monowave LED light-curing unit (LCU). In resin mixtures based on equal weight percent (wt%) of
Dong-Hee Shin et al.
Photomedicine and laser surgery, 29(8), 545-550 (2011-03-23)
This study evaluated the effectiveness of the diode-pumped solid state (DPSS) laser as a light source for light-curing dental resin composites. A DPSS laser of 473  nm may be useful because of its match with the absorption peak of camphorquinone

The journal of physical chemistry. A, 113(34), 9424-9433 (2009-08-07)
In this article, we report a study on the singlet and triplet excited-state properties of a spirooxazine (1,3-dihydro-3,3-dimethyl-1-isobutyl-6'-(2,3-dihydro-1H-indol-1-yl)spiro[2H-indole-2,3'-3H-naphtho[2,1-b][1,4]oxazine]). The singlet state of this molecule is photoreactive: upon UV light stimulation, it produces a colored merocyanine that thermally reverts to the
