Degree of conversion and hardness of an orthodontic resin cured with a light-emitting-diode and a quartz-tungsten-halogen light
(OxfordPorto Alegre, 2010)
The purpose of this study was to assess the influence of two light units, a quartz-tungsten-halogen (QTH) and a light-emitting-diode (LED) on the hardness and degree of conversion of an orthodontic composite resin.Sixty ...
Influence of the curing mode on the degree of conversion of a dual-cured self-adhesive resin luting cement beneath ceramic

Contraction stress determinants in dimethacrylate composites
(INT AMER ASSOC DENTAL RESEARCHI A D R/A A D R, 2008)
The influence of composite organic content on polymerization stress development remains unclear. It was hypothesized that stress was directly related to differences in degree of conversion, volumetric shrinkage, elastic ...
Composite pre-heating: Effects on marginal adaptation, degree of conversion and mechanical properties
(ELSEVIER SCI LTD, 2010)
Objectives. This study evaluated the effect of composite pre-polymerization temperature and energy density on the marginal adaptation (MA), degree of conversion (DC), flexural strength (FS), and polymer cross-linking (PCL) ...
Monomer conversion of composite dental resins photoactivated by a halogen lamp and a LED: a FT-Raman spectroscopy study
(2005)
Eighteen circular blocks of resins cured either by a LED or a halogen lamp (20, 40 and 60 s), had their top (T) and bottom (B) surfaces studied using a FT-Raman spectrometer. Systematic changes in the intensity of the ...
Contraction stress related to composite inorganic content
(ELSEVIER SCI LTD, 2010)
Objectives. The role of inorganic content on physical properties of resin composites is well known. However, its influence on polymerization stress development has not been established. The aim of this investigation was ...
Influence of hemostatic solution on bond strength and physicochemical properties of resin cement
(2017-09-01)
The aim of this study was to evaluate the degree of conversion, color stability, chemical composition, and bond strength of a light-cured resin cement contaminated with three different hemostatic solutions. Specimens were ...
The effect of curing light and chemical catalyst on the degree of conversion of two dual cured resin luting cements
(SPRINGER LONDON LTDLONDON, 2012)
The aim of this study was to evaluate the influence of different curing lights and chemical catalysts on the degree of conversion of resin luting cements. A total of 60 disk-shaped specimens of RelyX ARC or Panavia F of ...
