Changes in irradiance and energy density in relation to different curing distances
(Sociedade Brasileira de Pesquisa Odontológica - SBPqO, 2015)
The present study aimed to assess the influence of curing distance on the loss of irradiance and power density of four curing light devices. The behavior in terms of power density of four different dental curing devices ...
Could light-curing time, post-space region and cyclic fatigue affect the nanomechanical behavior of a dual-curing cement for fiber post luting?
(2022-01-01)
Objective: To evaluate the effects of curing time, post-space region and cyclic fatigue on the micromechanical properties of a fiber-post luting cement. The null hypotheses were that (1) curing time, (2) fatigue and (3) ...
Biaxial Flexural Strenght of high-viscosity glass-ionomer cements heat-cured with an LED lamp during setting
(Hindawi Pub. Co., 2013)
Adding heat to glass ionomers during setting might improve mechanical properties. The aim was to compare the biaxial flexural strength (BFS) between and within four glass ionomers, by time of exposure to a high-intensity ...
